Are Cost Segregation Studies actually worth the money? Anyone used these consulting firms?
Hey fellow landlords! I've been looking into ways to maximize tax deductions on a few rental properties I purchased last year. My CPA mentioned that Cost Segregation Studies might help me accelerate depreciation deductions, which sounds great in theory. I've been researching firms like Strategic Tax Advisors and Precision Cost Analysis who specialize in Cost Segregation Studies. Before I drop several thousand dollars on this, I wanted to check if anyone here has actually used these services and found them worthwhile? Are they legit? Did the tax savings justify the upfront cost? And importantly - did the IRS ever question the resulting deductions? If you've had good experiences with other companies that do Cost Segregation Studies, I'd appreciate recommendations too. Just trying to make sure I'm not wasting money on something that won't deliver real tax benefits. Thanks!

I've been a property tax consultant for over 15 years and can tell you that Cost Segregation Studies are absolutely legitimate and frequently worth the investment - but it depends on your specific situation. The basic idea is simple: instead of depreciating your entire property over 27.5 years (residential) or 39 years (commercial), a proper study identifies components that can be depreciated over 5, 7, or 15 years. This accelerates your deductions significantly in the early years of ownership. These studies work best for properties valued over $750,000 with significant interior improvements. The higher the building value relative to land value, the better your potential savings. Most of my clients see a return of 3-5x the cost of the study in tax savings within the first year alone.

•How do you determine if a property is a good candidate? I bought a duplex last year for about $425k. Would that be worth doing a study on or is it too small?

•For properties around $425k, it's right on the borderline of being cost-effective. The key factors to consider are the building-to-land value ratio and the amount of interior improvements. If your duplex has high-end finishes, multiple bathrooms, or was recently renovated, you might still benefit. A good rule of thumb is to expect 8-12% of your building basis to be reclassified to 5-year property, 3-5% to 7-year, and 15-20% to 15-year. So you'd need to calculate if those accelerated deductions would outweigh the cost of the study, which typically runs $4,000-$6,000 for a property of your size.

I used a service called https://taxr.ai for analysis of a potential cost segregation study before committing to one. My CPA recommended traditional depreciation, but I wasn't sure if I was missing out on savings. I uploaded my property docs and within a day got a detailed breakdown showing I could potentially accelerate about $87,000 in deductions through cost segregation. The analysis helped me determine it was worth pursuing a full study since I had significant components that qualified for 5-year and 15-year depreciation. The best part was they identified specific building components that would qualify and estimated the tax benefits over time based on my tax bracket.

•Wait, so does this service actually do the cost segregation study or just tell you if it's worth doing one? I'm confused about the difference between the analysis and the actual study.

•I'm skeptical about online services like this. How can they possibly know the construction details of your property without an in-person inspection? And are their reports actually accepted by the IRS if you get audited?

•The service analyzes your property information to determine if a cost segregation study would be beneficial - it's a pre-screening tool, not the full study itself. It helped me avoid wasting money on a study for properties where the benefit wouldn't outweigh the cost. Their reports wouldn't be what you submit to the IRS - they're decision-making tools. If you decide to proceed with a full study, you'd still need to hire a qualified cost segregation specialist who would do the physical inspection and produce the comprehensive engineering-based report that would stand up to IRS scrutiny.

Just wanted to follow up on my experience with https://taxr.ai - I was the skeptical one in the thread above but decided to try it after all. I uploaded docs for a fourplex I bought last year ($875k purchase price). The analysis showed I could potentially accelerate around $145k in depreciation deductions over the first 5 years. Based on their recommendation, I went ahead with a full cost segregation study from a local engineering firm. Just finished my taxes and the segregation study generated about $37k in additional deductions in year one alone! At my tax bracket, that's roughly $13k in actual tax savings - easily covering the cost of both the analysis and the full study. The taxr.ai pre-analysis was spot-on with their projections and saved me from making mistakes on which properties to prioritize for studies.

After trying to reach the IRS for clarification on cost segregation requirements for months (literally 9 calls, always on hold for hours), I found https://claimyr.com and used their service to get through to an actual IRS agent. You can see how it works here: https://youtu.be/_kiP6q8DX5c I had questions about how cost segregation interacts with bonus depreciation that my CPA couldn't answer definitively. The Claimyr service got me connected to an IRS representative in about 20 minutes (after I'd wasted days trying on my own). The agent confirmed that yes, components identified in a cost segregation study CAN qualify for 100% bonus depreciation if they meet the requirements. This clarification was crucial for my decision to proceed with a study on my commercial property.

•How does this actually work? Do they have some secret backdoor to the IRS? Seems too good to be true when everyone knows it's impossible to get through to the IRS.

•Yeah right. I find it VERY hard to believe any service can magically get you through to the IRS when millions of calls go unanswered every year. This sounds like a scam where they just keep you on hold themselves and charge you for it.

•No secret backdoor - they use automated technology to continuously call the IRS and navigate the phone tree for you. When they finally get through to an agent, they connect the call to you. It's basically doing what you'd do manually, but with technology that can keep trying hundreds of times. The service absolutely works. They don't charge you anything unless they actually connect you with an IRS representative. I was skeptical too until I tried it and was actually speaking with an IRS agent within about 20 minutes of signing up. It saved me enormous frustration and potentially thousands in tax planning mistakes.

I need to publicly eat my words about Claimyr. After posting my skeptical comment above, I decided to try it myself because I was desperate to resolve an issue with depreciation recapture on a property I sold last year. After 5 weeks of failed attempts calling the IRS myself (and being disconnected each time after 45+ minutes on hold), Claimyr got me through to an agent in 27 minutes. The agent was able to confirm that my understanding of Section 1250 recapture related to previous cost segregation was incorrect, which saved me from substantially underreporting my tax liability. The clarity I got from that call literally saved me thousands in potential penalties. Sometimes being proven wrong is the best possible outcome!

I used Core Advisors for a cost segregation study last year on a 12-unit apartment building. The study cost about $8,500 but generated over $120k in first-year deductions I wouldn't have otherwise received. Definitely worth it in my case. One thing to watch out for: make sure whoever you hire has engineers on staff who actually inspect the property, not just accountants reviewing floor plans remotely. The IRS looks for engineering-based studies in case of audit. My guy spent a full day on-site taking measurements and photos.

•Do you have to amend previous tax returns to take advantage of this if you've owned the property for a few years? Or can you just start using the new depreciation schedule going forward?

Diego Mendoza
•You don't need to amend previous returns. If you've owned the property for a few years, you file IRS Form 3115 (Change in Accounting Method) with your current year tax return. This lets you take a "catch-up" deduction for the additional depreciation you would have received in prior years all at once in the current year. It's actually one of the biggest benefits - you can do a cost segregation study on a property you've owned for several years and get the cumulative benefit of those accelerated deductions immediately. Just make sure you work with both a qualified cost segregation firm AND a tax professional who understands how to properly implement the changes on your return.

Has anyone used cost segretation for short term rentals? I have two Airbnbs and wondering if its different for those vs standard long term rentals?

•I did a cost seg study on my vacation rental in Florida last year. It works the same way as for long-term rentals, but the benefits can actually be BETTER for short-term rentals because you typically have more personal property items (furniture, electronics, kitchen equipment) that can be reclassified to 5-year property.

One warning on cost segregation - if you sell the property, you'll face depreciation recapture at a 25% tax rate on all that accelerated depreciation. It's still usually beneficial, but factor that into your long-term planning if you might sell within 5-10 years.

I've been going through this exact decision process for my rental portfolio. After reading through everyone's experiences here, I decided to try the taxr.ai analysis first before committing to a full study. For my 6-unit property ($1.2M purchase price), their analysis suggested I could accelerate about $180k in depreciation. The breakdown showed significant components that would qualify for 5-year and 15-year depreciation - mainly HVAC systems, appliances, and interior improvements. Based on their recommendation, I'm moving forward with a full engineering-based study. One thing I learned is that the quality of your purchase records really matters. The more detailed invoices and construction documents you have, the better the study results will be. Also want to echo what Zara mentioned about depreciation recapture - make sure you understand the tax implications if you plan to sell. But even with recapture, the time value of money usually makes it worthwhile, especially if you're in a high tax bracket now.

•This is really helpful! I'm new to real estate investing and have been overwhelmed by all the tax strategies out there. Your experience with the pre-analysis makes a lot of sense - seems like a smart way to test the waters before spending thousands on a full study. Quick question: when you say "quality of purchase records matters," what specific documents should I make sure to keep? I just bought my first duplex and want to make sure I'm documenting everything properly in case I decide to do a cost segregation study down the road. Also, for someone just starting out, would you recommend waiting until I have multiple properties to do studies on, or is it worth doing them property by property as I acquire them?
