The SubTo community has figured out how to acquire real estate in ways most investors never consider. But once you own the property, the next question matters just as much. How much of what you earn are you actually keeping?
That is where CSSI comes in. The properties SubTo members hold are very likely sitting on tax savings that have never been captured. Cost segregation is one of the most powerful and underutilized strategies in real estate investing, and it works just as well on a creatively financed deal as it does on a conventional one. We are here to make sure SubTo members have access to the same tax strategies that institutional investors have been using for decades.
What is Cost Segregation?
Most property owners are depreciating their buildings on the default IRS schedule and leaving significant tax savings on the table. Instead of spreading your entire building over 27.5 or 39 years, a cost segregation study identifies items like flooring, cabinetry, specialty electrical, and site improvements that qualify for 5, 7, or 15-year schedules. Pair that with bonus depreciation, now restored to 100% in 2025, and eligible assets can be fully deducted in the year they’re placed in service.
On average, our studies deliver $50K to $100K in tax savings for every $1M in building costs.
Bigger Deductions, Sooner
By reclassifying building components into shorter depreciation schedules, cost segregation front-loads your deductions and puts more cash back in your hands.
Creative Finance Deals Qualify
The strategy is based on the property itself, not how it was acquired. Subject-to, seller finance, or traditional purchase, cost segregation applies the same way.

Who Qualifies for Cost Segregation?
Eligibility
A cost segregation study can benefit property owners with buildings or improvements placed in service after 1986 that have a remaining depreciable basis. Properties should have a cost basis of at least $200,000. The study works for both newly constructed buildings and properties owned for many years.
