RV Park & MHP After-Tax Estimator

By Kasing Ng, CPA, former Big 4 auditor

Every cost-seg calculator shows you the first-year deduction. Almost none show the two things that decide whether it is actually worth anything: whether you can use the loss this year, and what it costs you back at sale. This one does both. Thirty seconds, no signup.

Property type?

Purchase price?

Year placed in service?

Your marginal tax bracket?

How do you hold this deal??

Do you already own this property??

Advanced assumptions

Land portion of price (%)?

Short-life reclass override (%)?

State marginal income-tax rate (%)?

Want this run on your actual deal? This is the 30-second screen. The full read models the real lease-up, the passive-loss timing across the whole hold, the exit recapture net of a 1031, and a §481(a) catch-up if you already own the park — built and reviewed by a former Big 4 auditor, not a study salesperson.

Estimate only, not tax advice, and not a cost-segregation study. Figures use the property-type and §168(k) placed-in-service assumptions shown above; a real allocation requires an engineering cost-segregation study, and your actual result depends on your full return. State income tax is added only if you enter a rate under Advanced, and only as a flat add-on to the federal rate; several states decouple from federal bonus depreciation, which can change the deduction itself, and that state-by-state decoupling is not modeled here. Passive-activity treatment (IRC §469) depends on your facts, including real-estate-professional status. No engagement is created by using this tool. Kasing Ng, CPA — California License 139270.
