I worked with CSSI through Aaron Stratman. Aaron was gold. I’ve already recommended him to other investors!

Pretty darn amazing team that pull through when you need them. By the way the 1 star review above was given by a former star player for that same company caught red-handed with less than ethical … canned. And started a competing company. So please consider the source. And if “you” take your bitter and retaliatory review down I may consider amending mine.

Incredible team. Chris and team have helped me save so much on taxes! they go above and beyond, communicate effectively with my tax professionals, and know what they are doing more than anyone I’ve come across in the field. I have used their services on multiple occasions and know a handful of people who also utilized them through my recommendation!
I highly recommend giving them a dial and at the very least, speaking to them about what they can do to help you

I used the firm for a cost segregation study of a townhouse rental. The professionalism and finished report were great. I highly recommend using them. Dr. Dan Boyd is key to helping explain how things are done.

I recently utilized CSSI for a cost segregation study on my property in California, and I couldn’t be more pleased with the experience, particularly thanks to Daniel. Daniel was exceptionally knowledgeable throughout the entire process. He clearly understood the intricacies of cost segregation and was able to explain complex tax concepts in a way that was easy to understand. This made me feel very confident in the work being done. Beyond his expertise, Daniel was incredibly responsive. He consistently provided timely updates and promptly answered all my questions, which made the entire process smooth and stress-free. Thanks to Daniel’s expertise and efficiency, the cost segregation study was a great success, providing valuable insights for my property. I highly recommend Daniel and CSSI to anyone in California seeking a professional and effective cost segregation service.

CSSI and specifically Dan Boyd have had a major impact on my business. The Cost Segregation study we engaged with CSSI yielded significant savings to our company. Having limited accounting/tax experience I felt very confident with sharing my information with Dan. Dan was very thorough and always available for additional questions. Dan’s follow thru and professionalism were greatly appreciated.
The results of the study were more than acceptable. I would recommend Dan Boyd and CSSI to anyone searching for a competent, knowledgeable Cost Segregation company.

Financial Advisor

As a financial advisor, I appreciate working with professionals who combine technical expertise with outstanding client service, and Josh Jacobs and CSSI exceeded my expectations. The cost segregation study was thorough, well-documented, and completed on time. Communication throughout the engagement was excellent, and they made the entire process seamless. They clearly know their field and delivered tremendous value, and in fact, gave me information about a Grouping Election I was unaware of that helped even more than just the Cost Seg study would have on it’s own. They worked well with my CPA, and I wouldn’t hesitate to recommend them to anyone considering a cost segregation study.

Property Owner

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.
