The short-term-rental tax rules — material participation, bonus depreciation, the so-called STR loophole — reward getting the details right. These are the CPAs and cost-segregation firms investors actually name.
Two kinds of firm live here: CPAs who plan and file around STR-specific strategy, and engineering-based cost-segregation firms that accelerate depreciation on a property so more of it can be written off sooner. Plenty of investors use one of each. None of this is advice you should act on from a directory — it is a shortlist of who to call.
A CPA firm and education brand focused on real-estate investors, well known for teaching the short-term-rental tax strategy.
Cavmir take: An investor-focused firm with a heavy education arm — expect a structured planning engagement, not a quick one-off return.
Visit Hall CPA (The Real Estate CPA) →A proactive tax-planning firm for real-estate investors, run by the CPAs who wrote BiggerPockets' best-selling tax-strategy books.
Cavmir take: Their reputation is built on high-touch strategic planning, which usually means a premium engagement — not the cheapest place to just file a return.
Visit Keystone CPA →A large, engineering-based tax firm providing cost-segregation studies and related incentives, working alongside your existing CPA.
Cavmir take: A services and incentives firm that partners with your CPA rather than replacing it — it does the study and hands the numbers back to your preparer.
Visit KBKG →A cost-segregation firm popular with the STR and BiggerPockets investor crowd, offering both fast and fully engineered studies.
Cavmir take: The low-cost Rapid Report is questionnaire-based, not a full engineered study — fine for smaller homes, but confirm which tier you need for audit defense on larger properties.
Visit R.E. Cost Seg →A long-running, nationwide engineering-based cost-segregation firm serving both commercial and residential property owners.
Cavmir take: Because they often reach you through your accountant, get the scope and pricing in writing directly before you commit.
Visit CSSI — Cost Segregation Services →Cavmir is a marketing agency, not an accounting or tax-advisory firm, and nothing here is tax advice. The short-term-rental tax rules are fact-specific and change — talk to a licensed CPA about your own situation before making any decision.
We will leave the depreciation schedules to the firms above. If the other side of the ledger — bookings and revenue — is what needs work, that part is us.
