About QuickPropertyCalc

QuickPropertyCalc is a free suite of real estate financing calculators built for people who structure deals — homebuyers comparing terms, investors underwriting rentals, and sellers putting together owner-financed and wraparound transactions.

Everything runs client-side in your browser: no accounts, no uploads, no tracking of your deal numbers. Each calculator produces a complete amortization schedule you can expand, export to CSV, and print as a clean summary.

The flagship tool is the Wraparound Mortgage Calculator, which models both the existing underlying loan and the new wrap note side by side — monthly spread, equity spread, seller IRR, dual amortization, and timeline warnings for mismatched balloons.
