Frequently Asked Questions
Common questions from CPAs evaluating the program.
What is the RentalWriteOff CPA Program?
The CPA Program is how RentalWriteOff works with accountants and tax professionals whose clients own residential rental properties. We deliver fast, IRS-compliant cost segregation studies so your clients can accelerate depreciation without you having to add cost segregation expertise to your practice.
How fast is turnaround?
Two business days from complete submission. Every report is built from a standardized engineering-based methodology with a final quality review before delivery.
What property types do you support?
Residential rental properties up to 4 units: single-family rentals, condos, townhouses, duplexes, triplexes, fourplexes, short-term rentals (Airbnb/VRBO), and manufactured housing.
What does the report include?
Every report includes reclassified asset schedules broken out by 5-, 7-, 15-, and 27.5-year recovery periods, cost basis allocations, photo documentation, methodology notes, and the supporting detail your CPA or tax software needs for Form 4562 or Form 3115.
Do look-back studies work for prior-year properties?
Yes. For properties placed in service in a prior year, a look-back study provides everything your CPA or tax software needs to file Form 3115 and claim missed depreciation as a Section 481(a) catch-up deduction on the current return. RentalWriteOff does not file Form 3115; we provide the supporting engineering-based report.
What is included with audit support?
If a client is audited, we provide the supporting documentation for the study and respond to reasonable inquiries from the taxing authority about our methodology and calculations. Audit support is included with every report.
