Selected commercial properties are also available, subject to scope review.

What’s Included

We prepare the study. Your firm advises the client.

You keep the professional relationship; we support the study, deliverable, and methodology.

Your brand on the report

White-label partners deliver the study under their own firm name, on the intake page their client sees and on the report itself.

Study support

We answer questions about the report, supporting documentation, asset classifications, and methodology. Your firm retains responsibility for tax and filing advice.

CPA-ready schedules

Reports include asset-classification and depreciation schedules plus methodology documentation for your firm’s independent review.

2-business-day delivery

Turnaround built around extension season and estimated-payment deadlines, not engineering-firm queues. Five-minute client intake, fully remote.

Revisions and audit support

One round of revisions included with every partner study. If a study is ever examined, we provide the documentation and respond to inquiries.

Property Focus

Built for the properties in your clients’ portfolios

Most cost segregation providers are built for office towers and treat residential as an afterthought. Residential rentals, condos, small multifamily, short-term rentals, and manufactured housing are our core practice, with selected commercial work available after scope review.

That focus is why the economics work at residential scale: a five-minute intake, no site visit, and a study back in 2 business days at a price point your clients say yes to.

Partner program FAQ

Can a CPA firm offer cost segregation without hiring an engineer?

Yes. Through the RentalWriteOff partner programs, your firm offers cost segregation while our team performs the analysis. In the white-label program the report is delivered under your firm’s brand at a price you set; in the referral program you share a tracked link.

What is the difference between the white-label and referral programs?

White-label partners access partner pricing, set their own retail price, deliver under their own brand, and own the client relationship. Referral partners share a tracked link and RentalWriteOff delivers the study.

What property types do you cover?

Residential rental property up to 4 units: single-family rentals, condos, townhouses, duplexes, triplexes, fourplexes, short-term rentals, and manufactured housing. That focus is why the turnaround and economics work at residential scale.

What does the report include for my tax team?

Reports include asset-classification schedules, depreciation schedules, methodology documentation, and supporting detail for your firm’s independent review. Your firm remains responsible for return preparation and filing decisions.

How long does setup take?

About 20 minutes. Your partner code, branded intake link, and portal access are created in one step, and our support desk is behind your clients from the first study.

Who answers my client’s technical questions?

RentalWriteOff supports questions about the report, supporting documentation, asset classifications, and methodology. Your firm handles tax advice and filing questions.

How fast are studies delivered?

2 business days from complete submission, a turnaround built for extension season and estimated-payment deadlines.

Are the studies defensible in an audit?

Every study is prepared with an engineering-based approach aligned with the IRS Cost Segregation Audit Techniques Guide, passes an expert review before delivery, and includes one round of revisions and audit support: if a study is examined, we provide the documentation and respond to the taxing authority’s inquiries.

What does the white-label program cost?

Partner pricing for standard studies is confirmed during onboarding. Selected commercial or non-standard work is scoped separately. Qualified new partners may receive a complimentary first standard residential study.
