Meet Tami Simko
Cost Segregation Expert
Since 2008, I’ve helped more than 1,000 commercial property owners across the United States unlock hundreds of millions of dollars in additional cash flow through cost segregation. I work directly with property owners and their tax professionals to deliver accurate, engineering-based studies that fully comply with all IRS guidelines.
Cost segregation is ultimately about the time value of money. While buildings are typically depreciated over 27.5 or 39 years, many components such as cabinetry, carpeting, and lighting, can be reclassified into shorter 5, 7, and 15-year lives using this IRS-approved strategy. Accelerating depreciation increases deductions today, reduces taxable income, and significantly improves cash flow.
My approach is straightforward and transparent, with a focus on helping property owners keep more of their money working for them. Many of my clients use their tax savings to reinvest in their business, acquire additional properties, or pay down principal.
Whether you’re buying your first property or managing a multi-state portfolio, I understand that navigating complex tax regulations can be overwhelming. That’s why I simplify the process, providing clear guidance and personalized solutions tailored to your unique goals. From providing a free upfront estimate to ensuring full IRS compliance, I’m with you every step of the way.

What Clients Say
Tom S.
Commercial Real Estate Investor
Working with Tami was one of the best tax decisions we’ve made. She was incredibly thorough and clearly focused on helping us maximize legitimate tax savings. The cost segregation study significantly reduced our taxable income in the first year, and the documentation was clean and easy for our CPA to use.
Megan T.
Multi-Family Property Owner
We have done several properties with Tami because she took the time to understand and explain exactly how the tax savings would work. Her dedication to making sure we captured every available depreciation benefit really stood out. The first-year tax savings exceeded our expectations and improved our cash flow immediately.
