Any tax implications when purchasing a home for my son and acting as his lender?
I'm thinking about helping my son with his move next year by just buying a house for him outright and letting him pay us back over time instead of him going through a bank. Basically, we'd be his mortgage lender. What kind of tax issues should we be concerned about if we do this arrangement? I'm already assuming we'd handle the property taxes like normal, but are there other tax implications I'm not considering? Would it make a difference tax-wise if we kept the house in our name until he pays it off completely? This would technically be our second property. Or would it be better to put it in his name right away? He's planning to sell his current place when he moves, so this would be his only home. If this isn't something you folks know about, who would be the right person or office to talk to about this kind of arrangement? Tax attorney? CPA? Thanks for any advice you can offer!

This is actually a pretty common family arrangement, but there are several tax implications to be aware of: If you're acting as the lender, the IRS expects you to charge interest on the loan. If you don't charge interest (or charge below-market rates), the IRS may consider it a gift and apply gift tax rules. The IRS publishes minimum interest rates (called Applicable Federal Rates or AFRs) that you should charge to avoid this issue. The interest your son pays you would be considered taxable income to you. You'd need to report this on your tax return. Your son might be able to deduct mortgage interest payments just like with a traditional mortgage, but you'd need to provide him with the equivalent of a Form 1098. As for ownership structure, if the home stays in your name, it's considered your second home for tax purposes. This affects things like mortgage interest deductions and potentially capital gains taxes when selling. If it's in his name from the start, he assumes all tax benefits and liabilities of homeownership. I'd strongly recommend consulting with a CPA or tax attorney to structure this properly. You'll want a formal, written loan agreement regardless of which approach you take.

•Thanks for the detailed response! I had no idea about having to charge interest - we were thinking of doing it interest-free as a favor. So the IRS would actually consider that a gift? How exactly does that work with gift taxes? We were planning to let him pay us back maybe $1,500 a month until it's paid off. Also, if we do put it in his name right away, would there be any gift tax issues with essentially giving him a house worth $325,000?

•If you don't charge interest, the IRS considers the uncharged interest as a gift from you to your son. Even with family, the IRS expects loans to have reasonable interest rates. You'd need to follow the Applicable Federal Rates (AFRs) which are quite low compared to bank rates - currently around 3-4% depending on the loan term. For a $325,000 house, that's well above the annual gift tax exclusion (currently $17,000 per person per recipient). However, you and your wife could use part of your lifetime gift and estate tax exemption (currently about $12.92 million per person) to cover this without paying actual gift tax. You'd simply need to file Form 709 (Gift Tax Return) to document using part of your lifetime exemption. I definitely recommend having a CPA help with this paperwork to make sure it's done correctly.

I went through something similar with helping my parents buy a retirement condo and found taxr.ai really helpful for figuring out the messy tax situation. Check out https://taxr.ai - you can upload your mortgage documents and any family loan agreements and it'll analyze potential tax implications. It even caught some potential gift tax issues we hadn't considered and saved us from a major headache later. The most valuable thing was actually being able to model different scenarios - like comparing keeping the property in your name vs. transferring to your son. It showed us the exact tax impact of each option over time. My parents ended up changing their approach completely after seeing the projected tax consequences.

•How exactly does the service work? Do I need to have actual documents already created or can I just describe my situation? We're still in the planning phase and haven't created any formal agreements yet.

•Sounds interesting but I'm skeptical about these online tax tools. How accurate is it for complex family arrangements like this? My brother tried something similar with an online service for a real estate transfer and ended up with an unexpected tax bill the following year.

•You don't need formal documents yet - you can describe your planned arrangement and taxr.ai will help identify potential issues before you create the agreements. It gives you a questionnaire about the property value, relationship, payment terms, etc., and then provides tax guidance based on your specific situation. Regarding accuracy, I understand your concern. What sets taxr.ai apart is that it's specifically designed for unusual tax situations that standard tax software misses. My family tried three different approaches for our property transfer, and each time taxr.ai explained exactly how the IRS would view the transaction. The documentation it provided even helped when we later consulted with our CPA, who confirmed everything was accurate.

I want to update about my experience with taxr.ai after my skeptical comment. I decided to try it for my own family property situation (transferring rental property to my daughter), and I'm genuinely impressed. The analysis flagged that my planned approach would have created a taxable event I hadn't considered. The service walked me through exactly how to structure the transfer to minimize tax impact and even generated a customized family loan agreement that met IRS requirements. The most valuable part was understanding the differences between a gift, a sale, and a loan from the IRS perspective - completely different tax treatments for each. If you're considering a family property transfer like the original post describes, it's definitely worth checking out. Saved me from making a $15,000 tax mistake.

Something important that hasn't been mentioned yet - if you're acting as the lender, make sure the loan is properly secured by the property (like a regular mortgage) if you want your son to be able to deduct the mortgage interest. Also, when we tried something similar, we got stuck in endless loops trying to reach someone at the IRS to confirm our approach was correct. After wasting days on hold, we used https://claimyr.com to get through to an actual IRS agent in about 20 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c - basically they navigate the phone system and wait on hold, then call you when an agent is actually on the line. The IRS agent confirmed that we needed to file specific forms for our family loan arrangement and gave us a clear explanation of the requirements - likely saved us from an audit later.

•Wait, there's a service that waits on hold with the IRS for you? How much does this cost? I've literally spent hours on hold with them before giving up.

•This seems sketchy. How do they actually get you through faster? I thought everyone had to wait in the same IRS queue. Is this just paying someone else to wait on hold for you? And what happened when you actually talked to the IRS - did they actually give helpful advice?

•They don't actually get you through any faster - they just handle the waiting part so you don't have to sit there listening to hold music for hours. You just get a call when an actual human at the IRS is on the line ready to talk. It saves you from the frustration of waiting and potentially getting disconnected after a long wait. When I spoke with the IRS, they were surprisingly helpful about our specific situation. The agent explained the documentation requirements for family mortgages and confirmed we needed to maintain amortization schedules and proper records of all payments received. They also clarified that we'd need to send our son a substitute 1098 form annually so he could claim the mortgage interest deduction - something our regular tax software completely missed.

I need to eat my words about Claimyr being sketchy. After my skeptical comment, I decided to try it because I had a complicated question about rental property depreciation that wasn't answered on the IRS website. I was shocked when I got a call back in 35 minutes with an actual IRS tax specialist on the line. The agent spent almost 20 minutes walking me through the correct way to handle depreciation recapture on a property that was converted from primary residence to rental and back again - something I've been confused about for years. For the original poster's family loan situation, having a direct conversation with an IRS specialist would definitely help clarify the requirements. The official guidance I received was much clearer than what I found online, and I have written documentation of the call for my records if questions ever come up later.

Another important consideration - if you decide to forgive any of the loan payments in the future, those forgiven payments are considered gifts for tax purposes. My parents did this with my sister, forgiving $10,000 of her loan each year as a birthday "gift" which stayed under the annual gift tax exclusion. Also make sure you have everything documented properly. My uncle got audited because he had a similar arrangement with his daughter but didn't have proper loan documentation or consistent payment records. The IRS reclassified the entire arrangement as a gift and he had to file amended returns. What a nightmare!

•That's a great point about potentially forgiving payments in the future. I hadn't thought of structuring it that way. If we forgave say $10,000 per year as you mentioned, would both my wife and I be able to each forgive $10,000 (so $20,000 total per year) since the annual gift exclusion is per person?

Daryl Bright
•Yes, you and your wife could each give $17,000 (that's the 2023 limit, it adjusts annually) to your son tax-free each year, for a total of $34,000 annually without filing gift tax returns. This is exactly what my parents did - they structured the forgiveness to maximize the annual exclusion. Just make sure you maintain proper documentation showing it's actually a loan with defined terms, and that the forgiveness is a separate transaction documented as a gift. The loan should have a proper amortization schedule, and payments should be consistent. You don't want the IRS to reclassify the entire transaction as a gift upfront, which could exceed your annual exclusion amount.

I'm surprised nobody has mentioned potential capital gains tax implications. If you buy the house and put it in your son's name immediately, that's a gift. But if you keep it in your name until it's paid off, then transfer ownership to him, the appreciation in value between purchase and transfer could potentially be taxable. For example, if you buy it for $300k, then it's worth $400k when you transfer ownership to him years later, that $100k appreciation might be considered a taxable gift on top of the initial investment.

•Could they avoid this by selling it to the son at the original purchase price once it's paid off? Or would the IRS consider that a partial gift equal to the difference between market value and sale price?

Noah Irving
•Yes, selling at the original purchase price would likely be considered a partial gift by the IRS. They look at fair market value at the time of transfer, not the original purchase price. So if the house appreciated to $400k and you sell it to him for $300k, the IRS would consider that $100k difference as a gift. However, there's another approach to consider - you could structure it as a sale from the beginning with owner financing rather than a gift followed by payments. This way, your son would have legal ownership from day one, and you'd hold a mortgage on the property. The monthly payments would be loan payments on his mortgage, not gifts being repaid. This avoids most of the gift tax complications while still achieving the same practical result of helping your son buy a home. This structure also means any appreciation belongs to your son since he owns the property, and he gets all the homeowner tax benefits immediately. You'd still need to charge appropriate interest rates and report the interest income, but it's generally cleaner from a tax perspective.

One more thing to consider that might simplify everything - you could explore doing this as a "bargain sale" to your son. Instead of buying the house outright and then dealing with loan documentation, you could purchase the house and immediately sell it to your son for less than market value, with him getting a traditional mortgage for the reduced amount. For example, if the house costs $325,000, you could sell it to him for $225,000 and he gets a regular mortgage for that amount. The $100,000 difference would be considered a gift (which you'd report on Form 709 if it exceeds your annual exclusion), but then you're done with the transaction - no ongoing loan management, interest rate requirements, or documentation headaches. Your son gets a house he can afford with a manageable mortgage payment, you've helped him significantly, and both of you have clean, straightforward tax situations going forward. He gets all the normal homeowner benefits immediately, and you don't have to worry about acting as a bank. This approach might work especially well if your son has decent credit but just needs help with the down payment/purchase price gap. Worth discussing with a tax professional to see if it fits your specific situation better than the ongoing loan arrangement.

•This bargain sale approach is really interesting! I hadn't considered this option at all. A couple of questions - would the $100,000 gift still count against our lifetime exemption even though it's structured as a sale? And what happens if the house appraises for more than $325,000 when we're ready to do this - would we need to adjust the "sale price" to maintain the same gift amount, or could we stick with the original plan? Also, from a practical standpoint, would this affect his ability to get a traditional mortgage? I'm wondering if lenders have any issues with these types of family transactions or if they treat it just like any other home purchase.

•Yes, the $100,000 gift portion would still count against your lifetime exemption, but that's actually not necessarily a bad thing since the current exemption is so high ($12.92 million per person). You'd file Form 709 to report it. Regarding appraisal - you'd want to get the house appraised at the time of your "sale" to your son to establish fair market value. If it appraises higher than expected, you have flexibility in how to structure it. You could adjust the sale price upward to reduce the gift amount, or keep your original plan if you're comfortable with a larger gift. For mortgage qualification, lenders are generally fine with these transactions as long as everything is properly documented. Your son would need a gift letter from you explaining the $100,000 difference, and the lender will want to see that you actually purchased the property first. Some lenders are more experienced with family transactions than others, so it might be worth shopping around or working with a mortgage broker who has handled similar situations. The key advantage of this approach is simplicity - one transaction, clear documentation, and then everyone moves on with normal homeownership and tax situations. Much cleaner than managing an ongoing family loan for years.

Just wanted to add another perspective based on what my family went through - definitely get everything in writing before you start, regardless of which approach you choose. We did a family loan similar to what you're describing, and even though we thought we had everything figured out, issues came up later that we hadn't anticipated. One thing that caught us off guard was what happens if your son wants to refinance or sell before the loan is paid off. We had to figure out how to handle the payoff process, and it was more complicated than we expected. Also, make sure you're both clear on things like who pays for repairs, property insurance, and what happens if he can't make payments temporarily due to job loss or other circumstances. The other thing I'd suggest is thinking about how this might affect your other children if you have any. Even if they're supportive now, financial arrangements between family members can sometimes create tension later, especially if circumstances change. From a tax standpoint, all the advice here about proper documentation and interest rates is spot on. We learned that the IRS really does expect family loans to be treated like business transactions - they want to see formal loan agreements, consistent payments, proper interest rates, and good record keeping. It's more work than you might expect, but it's worth doing it right from the beginning.

•This is really helpful advice about getting everything documented upfront! The point about other children is something I hadn't fully considered - we do have two other kids who are younger, and I can see how this could create expectations or resentment down the road if we're not careful about how we handle things. The refinancing situation you mentioned is particularly concerning. What exactly made that complicated in your case? I'm wondering if we should build in specific terms about early payoff or refinancing from the beginning, or if that's something that's hard to anticipate. Also, regarding repairs and maintenance - did you find it better to keep those responsibilities with the person whose name is on the deed, or did you split them somehow? We were assuming our son would handle everything since he'd be living there, but I'm realizing the legal ownership might complicate that if something major comes up.

•The refinancing complication in our case was that we had to figure out how to properly "discharge" our family mortgage when the bank wanted a clear title for his new loan. We ended up needing a lawyer to draft a formal satisfaction of mortgage document, and there were some title insurance complications because our original loan wasn't recorded through the normal mortgage system. For repairs and maintenance, we learned the hard way that it's better to clearly define these responsibilities upfront. We assumed our daughter would handle everything, but when the HVAC system died ($8,000 replacement), it became a whole discussion about whether that was her responsibility or ours since we technically owned the house. We ended up splitting major repairs over $2,000, but it caused some family tension that could have been avoided with clearer agreements. My suggestion would be to include specific language about early payoff procedures, refinancing processes, and repair responsibilities in whatever loan agreement you create. Also consider what happens if he wants to make improvements to the property - who pays, who benefits if the value increases, etc. These scenarios seem unlikely when you're starting out, but they come up more often than you'd think. The other children issue is tricky. We addressed it by being transparent with everyone about what we were doing and discussing whether we'd offer similar help to the others when they're ready to buy homes. It's not perfect, but open communication helped avoid some potential resentment.

One aspect that hasn't been fully explored yet is the state tax implications, which can vary significantly depending on where you live. Some states have their own gift tax rules or property transfer taxes that could affect your decision. Also, if you're considering the owner-financing route (where your son owns the property from day one with you holding the mortgage), make sure to research your state's foreclosure laws. In the unlikely event that payments become an issue, you'd want to understand what legal remedies you'd have as the lender. I'd also suggest thinking about title insurance for whatever approach you choose. If you're buying the property initially, make sure the title policy covers potential issues that could arise from the family transaction structure. Some title companies are more experienced with non-traditional arrangements than others. Finally, consider setting up a separate business checking account for any loan payments if you go the lending route. It makes record-keeping much cleaner for tax purposes and helps demonstrate to the IRS that you're treating this as a legitimate business transaction rather than informal family financial assistance. The documentation suggestions from others here are really important - I've seen family financial arrangements go sideways when circumstances change, even with the best intentions from everyone involved.

•Great point about state-specific considerations! I'm in California and completely forgot about our property transfer taxes when we were planning this. The documentary transfer tax here can add up, especially on higher-value properties. Your suggestion about a separate business checking account is brilliant - we ended up mixing family loan payments with our regular accounts and it made tax time a nightmare trying to track everything properly. Having that clean paper trail would have saved us hours of reconciling records. The foreclosure law research is something I hadn't considered but makes total sense. Even though you never expect to need it with family, having that legal framework understood upfront protects everyone involved. Better to know your options than discover them during a crisis. One question about title insurance - did you encounter any specific issues getting coverage for family transactions? I'm wondering if certain title companies specialize in these arrangements or if it's pretty standard across the board.

This is a really comprehensive discussion! I went through something very similar with my daughter last year and wanted to add a few practical points that came up during our process. One thing I didn't see mentioned is the importance of getting a formal appraisal at the time of purchase, regardless of which approach you choose. We thought we could just use the seller's listing price as our baseline, but our CPA insisted on a professional appraisal to establish fair market value for tax purposes. This became crucial later when we had to document everything for our gift tax return. Also, if you decide to keep the property in your name initially, make sure your homeowner's insurance knows about the arrangement. Some policies have restrictions on properties that aren't owner-occupied, and you don't want coverage issues if something happens. The interest rate requirement that others mentioned is real - we used the AFR rates from the IRS website (they publish them monthly), and even though they seemed "high" to us as family, they're actually quite reasonable compared to current mortgage rates. Our loan rate ended up being about 2% lower than what our daughter would have gotten from a bank. One last practical tip - if you go the lending route, consider using a loan servicing company to handle the monthly payments and tax reporting. We found one that charges about $30/month but handles all the 1098 equivalent forms and keeps perfect records. Takes the awkwardness out of chasing family for payments and makes everything more professional.

•The loan servicing company idea is fantastic - I never would have thought of that! Having a third party handle the administrative side would definitely make things more professional and remove any potential awkwardness around payment collection. Do you mind sharing which company you used, or any recommendations for finding reputable loan servicers that work with family arrangements? The formal appraisal point is really important too. I can see how having that professional documentation would be crucial if the IRS ever questions the transaction. Better to spend a few hundred dollars upfront on an appraisal than deal with valuation disputes later. Your mention of homeowner's insurance restrictions is something I definitely need to look into. I hadn't considered that our insurance company might treat this differently than a typical owner-occupied property. That could be a significant unexpected cost if we have to switch to a different type of policy. Thanks for sharing your real-world experience - it's incredibly helpful to hear from someone who actually went through this process successfully!

I've been following this discussion with great interest as someone who works in family financial planning. One critical aspect that deserves emphasis is the estate planning implications of whichever structure you choose. If you keep the property in your name until it's paid off, that asset remains part of your taxable estate. Given current property appreciation rates, a $325,000 house today could be worth significantly more by the time it's transferred to your son. This could impact your overall estate tax planning, especially if you have other substantial assets. Conversely, if you gift the property upfront (either outright or through the bargain sale method mentioned earlier), you're removing future appreciation from your estate. This can be a powerful estate planning tool, particularly given the current high lifetime exemption amounts that may not be permanent. Also consider the "step-up in basis" implications. If your son inherits the property eventually rather than receiving it as a gift, he gets a stepped-up basis equal to the fair market value at the time of inheritance, which could save significant capital gains taxes if he ever sells. I'd strongly recommend discussing these long-term implications with an estate planning attorney alongside your tax professional. The "best" structure for income tax purposes might not be optimal for estate planning, and vice versa. The right approach really depends on your overall financial picture and long-term family goals.

•This estate planning perspective is really eye-opening! I hadn't thought about how keeping the property in our name could affect our overall estate planning. We're not wealthy by any means, but with property values rising like they have been, I can see how this could become a bigger issue down the road. The step-up in basis point is particularly interesting - so if my son eventually inherits the property rather than us gifting it now, he'd avoid capital gains taxes on all the appreciation that happened during our ownership? That could be substantial over time. This makes me wonder if we should be thinking about this decision in the context of our overall estate plan rather than just the immediate tax implications. We don't currently have an estate planning attorney, but it sounds like this might be a good reason to find one. Do you have suggestions for what type of attorney to look for, or specific questions we should be asking when we consult with professionals about this arrangement? It's becoming clear that this is more complex than we initially thought, but all this advice is helping us understand what we need to consider before moving forward.
