I · On Our Practice
A firm, narrowly devoted.
Pinnacle exists for a single purpose: to produce cost segregation studies that withstand scrutiny, accelerate depreciation lawfully, and return capital to the owners of commercial and income-producing real estate.
We are not a marketplace. We are not software alone. We are a small firm of licensed cost segregation engineers and tax specialists who have prepared IRS-compliant studies for more than a decade, and who now offer the first mile of that analysis free, instantly, to any owner who asks.
When a study is not warranted, we say so. When one is, we do the work ourselves — the modeling approach for smaller assets, the fully engineered approach for larger and more complex ones. Both are IRS-recognized. Neither is fragile.
II · Recent Studies
Recent studies.
A selection of recent engagements. Names of principals are withheld; figures are approximate and represent identified depreciation acceleration, not cash paid.

Candor, quietly returned.
We'd closed on a $24M multifamily acquisition and our CPA told us we'd be leaving money on the table without a cost segregation study. Pinnacle produced a clean, CPA-ready engineered report on time and we claimed every dollar we were entitled to in the first year.
Their free analysis told us, honestly, that our small rental didn't need a $6,000 engineered study. We ordered the $500 modeling report instead, the CPA accepted it, and the refund arrived without friction. You don't forget being told what you actually need.
The engineered study identified an additional $3.6M of accelerated depreciation on our Phoenix industrial portfolio. Under OBBBA that was substantial cash back the first year. Pinnacle managed the 3115 filing and the IRS correspondence without drama.
