BRRRR Calculator

What you pay to acquire the property, before rehab.

Total renovation budget: materials, labor, permits, surprises.

Appraised value once the rehab is done — drives the refinance loan amount.

Gross rent before expenses. Compare to the 1 % rule (rent ≥ 1 % of all-in).

Conventional investment-property cash-out refis usually cap at 70–75 % of ARV.

Quote from your lender. Investment property rates typically run 0.5–1 % above primary.

30-year fixed is the default. Shorter terms lower total interest but raise the monthly.

Property tax + insurance + HOA + maintenance + PM + vacancy reserve. Not the mortgage payment.

Utilities, insurance, interest on short-term financing during the rehab window. Adds to all-in cost.
