Calculators
Run the numbers before you commit
Free, no sign-up, nothing saved. These include vacancy, capital reserves and management by default — which is why the returns look lower than the listing pro forma, and closer to what you will actually experience.
Rental property calculator
Pencil out a rental purchase: cap rate, cash-on-cash return, DSCR, monthly cash flow, and the 1% rule — with vacancy and reserves included.
OpenRenovation ROI calculator
Will this renovation pay for itself? Payback period, rent lift, equity added, and five-year return on a rental improvement.
OpenRefinance calculator
Rate-and-term refinance analysis: monthly savings, break-even on closing costs, and lifetime interest difference.
OpenCash-out refinance calculator
How much equity can you pull out? Maximum cash available at your LTV limit, the new payment, and the effective rate on the cash you take.
