Great to work with, I did 5 cost segregations with them and they all went smoothly. Once I gave them the information on the properties it was completely hands off for me and the turnaround time was very quick.

CSSI agent David Smith struck up a conversation a few years prior about what he did with the company and I’ll be honest I was half listening and half working. Luckily the half listening part stuck. He had discussed cost seg with me based on knowing that we had some commercial real estate. He recommended that if we had any large buildings we should look at doing it. Well fast forward we ended up with a 22,500 sq foot building with lots of equipment and CSSI came out and help us and it has been amazing at the amount of money it has saved us. Thank you David for knowing your trade and sharing with us.

Todd Strumpfer and the team at CSSI were dedicated and went the extra mile to ensure my cost segregation was completed in time and done correctly. Despite how challenging the project was, they were always patient and professional. This is the second time that I used CSSI for a cost segregation. I was impressed both times. I highly recommend Todd and CSSI for their knowledge, experience, and the level of commitment they put into client projects.

I needed CSSI Services for cost segregation of my short-term rentals and found their free analysis really good. The company was introduced to me by Kamilla, who explained the benefits very well. CSSI Services gave me the most thorough work with the highest tax advantages compared to two other companies. I appreciate their timely responses to emails and the availability to call Kamila when needed. They matched the promised numbers on the quote, delivered on time, and helped maximize my tax benefits. I also like that they have engineers run the study. The company is easy to deal with, professional, and offers IRS support if needed, giving me peace of mind. I also appreciate that I can always speak to one person who knows my situation, rather than a bot or chat.

As a CPA, I know the value that cost segregation can bring to a commercial building owner. In fact, it’s one of the many tax strategies I discuss with my clients.

Tom is professional, thorough, and has helped my clients collectively uncover millions of dollars in accelerated depreciation!

I had just bought two vacation rental properties, and had heard about cost segregation, but didn’t know who to use, so I asked around and got Tom Brodie’s name. We talked on the phone, and I told him about the two new properties and Tom explained how the process worked. Then he asked me if I had any other commercial properties. I said yes, but since I had owned some of them for several years, I didn’t think we could study those properties. He then told me about the Change of Accounting form and the fact that it wasn’t too late to study ALL my commercial properties! The combined result from studying all 13 of my properties was amazing, much better than I could have hoped for! When I mentioned to Tom that I needed a new CPA to handle all my real estate investments, he gave me a great recommendation! I couldn’t be happier with the total results, both the study and the new CPA that was VERY familiar with cost segregation and handling real estate investments!

Amazing service and super quick turnaround. We reached out to CSSI to perform a cost seg studies for our 3 multifamily properties. Received a call back within 10 minutes and initial estimate of high and low range of additional depreciation expenses within 48 hours. We also got a quote from other 3 local companies and not a single one came even close in terms of pricing, turnaround time or detailed outcome. One firm sent me 30 pages questionnaire and requested one million reports to even give me a quote and demanded a non-refundable deposit. We were able the schedule the inspection within days and my reports came in within 2 weeks just as promised. Thank you, Aaron, and CSSI Services.
