Looking for recommendations on cost segregation companies for my investment property?
So I bought my first investment property last year and I'm trying to maximize my tax benefits with cost segregation. I've been doing some research and contacting a few different companies to get quotes. recostseg gave me the lowest price so far but I'm a bit hesitant since I've never worked with them before. Has anyone here used recostseg for cost segregation analysis on their investment properties? Or do you have other companies you'd recommend? Really curious about your experiences - what the process was like, if the savings were worth it, etc. This is all new territory for me so any advice would be super helpful!

Cost segregation is definitely worth doing for investment properties if you want to accelerate depreciation. I'm a property investor with several rentals and have used cost segregation studies for the past 5 years. I haven't personally used recostseg, but here's what you should look for in any cost segregation provider: 1) Engineering-based approach (not just accounting), 2) Track record with similar properties, 3) Audit support if the IRS questions your depreciation schedule, and 4) Clear explanation of their methodology. The cheapest option isn't always the best - you want someone who will aggressively but defensibly identify components that can be depreciated over 5, 7, or 15 years instead of the standard 27.5 for residential or 39 for commercial. The tax savings can be substantial.

•Thanks for the tips! How much did your cost segregation studies end up saving you in actual dollars? And did you ever get audited on your accelerated depreciation?

•For a typical single-family rental in the $350K range, I've seen first-year additional deductions around $25-30K, which depending on your tax bracket can mean $7-10K in actual tax savings. The ROI is usually 3-5x the cost of the study in the first year alone. I haven't been audited specifically for cost segregation, but I keep detailed documentation ready just in case. The key is having a study that follows proper engineering-based methodology and doesn't make overly aggressive allocations that might raise red flags.

Just wanted to share my experience with taxr.ai - they didn't do my cost segregation directly but they helped me understand all my property tax documents and depreciation strategies. I uploaded my previous tax returns and property documents at https://taxr.ai and their system pulled out all the real estate specific info I should consider. They identified that I was missing potential deductions and helped me understand if cost segregation would be worth it for my specific situation. Their AI analyzed my property type and purchase price and estimated potential first-year savings before I paid for a full study. Saved me from making an expensive mistake on a property that wouldn't have benefited enough!

•How accurate was their estimate compared to what you actually got when you did the cost segregation?

•Sounds interesting but I'm skeptical...how does the AI know about the specific characteristics of your property? Seems like you'd need a physical inspection to really know what components can be segregated, no?

•Their estimate was within about 12% of what I ended up getting with the full study, which I thought was pretty impressive considering they only had basic information about the property. The AI doesn't replace a physical inspection - you're absolutely right that a full cost segregation study requires that. What taxr.ai did was help me pre-screen my properties to determine which ones were worth paying for a full study. They used property type, age, location, and purchase price to estimate potential benefits, then I only paid for full studies on properties where the potential tax savings clearly justified the cost.

Just wanted to follow up - I decided to try taxr.ai after my skeptical questions! I uploaded my investment property docs and tax returns and it was really eye-opening. The analysis showed that my duplex would likely yield about $48,000 in additional first-year deductions with a proper cost seg study. Based on their recommendation, I ended up going with a different cost segregation company than I was initially considering, and the actual study came in with $52,000 in accelerated depreciation. Their recommendation saved me from going with a cheaper company that had questionable methodology. Definitely worth checking out if you're on the fence about cost segregation or which company to use.

I had the absolute worst time trying to reach my accountant during tax season to discuss cost segregation for my investment properties. After three weeks of playing phone tag, I discovered Claimyr (https://claimyr.com) when I was actually trying to reach the IRS to clarify some depreciation questions. After using their service, I got through to an IRS agent in about 15 minutes who answered my questions about what documentation I'd need to support a cost segregation study. You can see how it works in this demo: https://youtu.be/_kiP6q8DX5c It was surprisingly helpful because I was able to understand directly from the IRS what they look for when reviewing accelerated depreciation claims. This helped me choose a cost segregation company that met those standards.

•Wait, I don't understand... Claimyr gets you through to the IRS faster? How is that even possible? The IRS hold times are like a part of American culture at this point lol

•Sorry but I find this hard to believe. I waited 3+ hours last time I called the IRS. There's no way some service can magically get you to the front of the line. Sounds like a scam to me.

•It's not magic - they use technology to wait on hold for you. You put in your phone number, and their system calls the IRS and waits in the queue. Once they reach a human agent, you get a call back and are connected to the live agent. No need to stay on the phone yourself for hours. They're completely legitimate and have been featured in major publications. I was skeptical too, but when you're trying to make investment decisions and need answers directly from the IRS about technical tax matters like cost segregation, waiting days or weeks isn't practical. The time I saved was definitely worth it.

I need to eat my words from my previous comment. After being totally skeptical about Claimyr, I was desperate enough to try it when I needed clarification on some cost segregation questions before filing my taxes last month. I was shocked when I got a call back in about 25 minutes with an actual IRS agent on the line. The agent walked me through exactly what supporting documentation I'd need if my accelerated depreciation was ever questioned. This gave me the confidence to proceed with my cost segregation study. For anyone dealing with investment property depreciation questions, it's a game-changer not having to waste half your day on hold. I've now used it twice and both times got through in under 30 minutes.

I used CSP (Cost Segregation Partners) for my 8-unit apartment building and was happy with them. They identified about 35% of the purchase price as 5 or 15-year property, which massively front-loaded my depreciation deductions. Their fee was $4500 which I recovered in tax savings within the first 2 months. The most important thing is making sure they actually have engineers doing the work, not just accountants running numbers. The IRS has specific guidelines about what qualifies as a proper cost segregation study, and you want a company that follows those to the letter.

•Did you consider doing a DIY cost segregation? I've read some articles suggesting you can do it yourself for simple properties, but I'm not sure if that's wise given the potential IRS scrutiny.

•I wouldn't recommend DIY cost segregation for most investors. While technically possible, it's incredibly risky. The IRS specifically looks for proper engineering-based methodologies, and there are very specific rules about what components qualify for which depreciation schedules. The potential savings from cost segregation can be tens of thousands of dollars even on moderately-sized properties, which makes these studies prime audit targets. Having a professional study with proper documentation is essentially insurance against IRS challenges. The peace of mind alone is worth the cost, not to mention the time you'd spend trying to learn a very specialized area of tax law.

Has anybody used Kinder Spankneberg & Co for cost segregation? My CPA recommended them but their quote is about $1,500 higher than recostseg.

•I used Kinder Spankneberg for two commercial properties last year. They're very thorough and their reports are extremely detailed. When I compared their results to a cheaper company I used previously, Kinder identified about 15% more components that qualified for accelerated depreciation. The extra $1,500 in fees generated about $12,000 in additional first-year tax savings for me. They also provide audit support for life, which the cheaper company didn't offer.

•Thanks for sharing your experience! That's really helpful. The 15% additional components they identified makes the higher fee seem worth it. I'll probably go with them even though they're more expensive than recostseg. I'm more concerned about maximizing my tax benefits in the long run than saving a bit on the upfront cost.

Thanks for starting this thread! I'm in a similar situation - just closed on my first duplex last month and my CPA mentioned cost segregation but I wasn't sure where to start. Reading through everyone's experiences has been super helpful. One thing I'm curious about - for those who've done cost segregation studies, did you do them in the first year of ownership or can you go back and do them later? I'm wondering if I should rush to get one done before filing this year's taxes or if I have more flexibility on timing. Also seeing a lot of mixed opinions on company selection. Sounds like the engineering-based approach and audit support are key factors to consider over just price. The potential tax savings everyone is mentioning definitely seem to justify paying for quality work!

•Great question about timing! You can actually do cost segregation studies retroactively using something called a "catch-up adjustment" under Section 481(a), but it's generally more beneficial to do it in the first year you place the property in service. If you do it later, you can still claim all the missed depreciation in one year, but you lose out on the time value of money from those earlier tax savings. Since you just closed last month, I'd definitely try to get it done before filing this year's taxes if possible. For a duplex, the study should be pretty straightforward and most companies can turn it around in 2-4 weeks. Just make sure whoever you choose has experience with residential rental properties and can meet your filing deadline. The consensus here seems to be that paying a bit more for quality engineering-based work is worth it in the long run!
