Can I write off the costs of seller financing when selling property to family?
I'm in the process of selling my beach condo to my son using seller financing since he probably wouldn't qualify for a traditional mortgage right now. After doing some research, I decided to use a third-party service that creates all the legal paperwork and handles the mortgage payments to make sure this qualifies as a legitimate installment sale at "arm's length" and keeps everything above board. The problem is, this third-party service isn't cheap - there's a pretty significant upfront fee and then monthly servicing charges. I'm familiar with how mortgage costs work from the borrower side (my son's position), but I have no idea how to handle these expenses from my end as the lender. Since I'll be receiving interest income from this arrangement, I'm thinking these fees might count as some kind of investment expense? Or maybe they're business expenses? Could they be considered part of the closing costs for the property sale? Or is the IRS just going to view this as a personal expense that doesn't qualify for any deduction? Has anyone dealt with seller financing before and know how to handle these third-party service costs on taxes? I want to make sure I'm accounting for everything correctly on my 2025 filing.

The good news is that you can generally deduct these expenses, but how you do it depends on how you're reporting the income from the seller financing. If you're treating this as an investment activity (which is most common for one-off seller financing), the fees paid to the third-party service would typically be considered investment expenses. The upfront fee would likely be capitalized and deducted over the life of the loan (similar to points on a mortgage), while the ongoing monthly servicing fees can be deducted as investment expenses in the year you pay them. On Schedule B where you'll report the interest income from your son, you can deduct the related expenses that are directly connected to that income. Just make sure you're keeping detailed records of all these fees. If you're doing this regularly enough to be considered a business activity, you'd report it differently on Schedule C, but for a one-time transaction with a family member, the investment approach is usually appropriate.

•Thanks for the detailed response! So if I understand correctly, the upfront fee gets spread out over the life of the loan (which is 30 years in our case), while the monthly fees can be deducted each year as they occur? Also, does it matter that the property was my primary residence for 15 years before becoming a rental property for the last 3 years? I'm wondering if that affects how these expenses are treated.

•The upfront fee would indeed be spread over the 30-year term of the loan. This works much like points on a mortgage - you don't get to deduct the entire amount in year one, but instead amortize it over the loan term. The property's history as your primary residence and then as a rental does add some complexity. Since it was most recently a rental property, you'll need to consider the impact on depreciation recapture and capital gains. The seller financing aspect doesn't change how you report the actual sale of the property - you'll still need to file Form 4797 for the business portion of the property sale. However, the loan itself is considered a separate financial arrangement, and the expenses related to setting up and servicing that loan would still be deducted against the interest income you receive.

After spending hours trying to figure out a similar situation with my investment property, I discovered taxr.ai and it saved me so much stress! I was confused about how to handle seller financing costs just like you, and their system analyzed all my documents and gave me clear guidance. Their AI actually found some deductions related to my third-party servicing fees that I didn't even know I could claim. I uploaded my third-party service contract at https://taxr.ai and it highlighted exactly which portions of my fees were immediately deductible versus what needed to be amortized. It even generated the proper schedule for amortizing the upfront costs over the loan term. Super helpful when you're dealing with something complicated like seller financing!

•Can this service handle complicated family transactions? I'm helping my parents sell their lake house to my brother with owner financing and the tax implications seem really confusing.

•Is it really worth paying for another service? I've already spent so much on the third-party company handling the financing paperwork. Couldn't I just ask my CPA to figure this out?

•It absolutely handles family transactions - that's actually where it shines because those related-party rules can get super complex. It specifically identified the "arm's length" requirements I needed to document for my family transaction and explained exactly how to maintain the proper legal separation. As for whether it's worth it compared to just asking your CPA - I initially thought the same thing, but my CPA was actually the one who recommended it. Many CPAs use it themselves because it helps them analyze documents more quickly. My CPA charges $250/hour, and this saved him at least 2-3 hours of research time, so it was definitely cost-effective in my situation. Plus, I now have documentation backing up my tax position if there's ever a question.

I just wanted to follow up about my experience with taxr.ai for my parents' seller financing situation. After seeing the recommendation here, I decided to give it a try since our situation was pretty complex - my parents selling their lake house to my brother using seller financing with some unique conditions. I uploaded our financing agreement and the third-party servicing contract, and the system immediately identified which expenses could be deducted immediately versus amortized. It even flagged a potential issue with our interest rate being below market rate, which could have caused gift tax complications! We were able to adjust our agreement before finalizing everything. The detailed explanation of how to handle the servicing fees on Schedule B versus what needed to be capitalized saved me hours of research. I'm actually kind of amazed at how well it worked for such a specific tax situation. Definitely worth checking out if you're dealing with seller financing.

If you're struggling to get clear answers from the IRS about how to handle these seller financing costs (I certainly did), I'd strongly recommend Claimyr. I kept calling the IRS for clarification on some specific points about seller financing deductions and couldn't get through for weeks. After wasting hours on hold, I tried https://claimyr.com and was honestly shocked at how well it worked. They got me connected to an IRS representative in about 20 minutes when I'd previously been waiting on hold for hours. The rep gave me specific guidance on how to report the third-party servicing fees and how to properly amortize the upfront costs. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c It was such a relief to get official clarification rather than just guessing or relying on internet advice for something as specific as seller financing to a family member.

•How does this actually work? I thought it was impossible to get through to the IRS right now. Are they somehow jumping the queue?

•Sounds too good to be true. I've tried calling the IRS dozens of times about my rental property issues and never got through. How would some random service be able to get you to the front of the line when millions of people are calling?

•It's not jumping the queue in an improper way - they use an automated system that continually calls and navigates the IRS phone tree until it reaches a live person. When it does, it automatically connects you. Basically it does the waiting for you, and you only get notified when there's actually a human ready to talk. The IRS is definitely overwhelmed right now, especially with tax season approaching. What this service does is handle the repetitive calling and waiting process so you don't have to keep your phone tied up all day. It's similar to how restaurants use those buzzers - you go about your day, and they notify you when your table (or in this case, an IRS agent) is ready.

I need to eat my words about Claimyr. After seeing it mentioned here, I was extremely skeptical since I've tried everything to reach the IRS about some questions on rental property sales and seller financing. Decided to try it anyway out of desperation - I had a deadline coming up for finalizing a seller financing agreement with my tenant who's buying my duplex, and I needed clarification on how to treat the origination fees I was paying. It actually worked! Got connected to an IRS rep in about 30 minutes when I'd been trying unsuccessfully for weeks. The agent confirmed that I should treat the upfront fees as points (amortized over the loan term) and the monthly servicing fees as investment expenses deductible against the interest income I'll receive. For anyone dealing with seller financing questions that aren't clearly addressed in IRS publications, this is definitely worth trying. Saved me from making some potentially costly assumptions.

Have you considered setting this up as an actual business? If you're doing this transaction and might do others in the future, you could potentially set up as a lending business and deduct all these expenses on Schedule C instead. The benefit would be immediate deduction of expenses rather than amortizing some of them over the loan term. There are specific requirements for being considered a business rather than just an investor, but if you meet them, it might be more tax advantageous. You'd need to show that you're engaged in the activity with continuity and regularity with the primary purpose of income or profit.

•That's an interesting angle I hadn't considered. This is my first time doing seller financing, but I do have two other rental properties that I might sell in the next few years. Would doing just 2-3 of these transactions be enough to qualify as a business? Or would I need to do this more regularly?

•Just 2-3 transactions over several years would probably not be enough to qualify as being in the lending business. The IRS would likely view that as investment activity rather than a business. To be considered a business, you'd typically need to show more regular activity and perhaps even advertise your services or create a formal business structure. Most people who do occasional seller financing end up treating it as investment activity and reporting it on Schedule B with the associated expenses offsetting the interest income. If you were doing multiple loans per year and actively seeking out opportunities to provide seller financing, that might cross the threshold into business territory.

Quick question for anyone who's handled seller financing before - which tax software best handles reporting these kinds of transactions? I used TurboTax last year but I'm not sure if it will properly guide me through the amortization of the upfront fees and the correct placement of the monthly servicing costs.

•I've done seller financing for several properties and found that H&R Block's premium version handled it better than TurboTax. It specifically asked about loan origination costs and gave clear guidance on amortizing them over the loan term. It also had a specific section for investment expenses related to interest income.
