Real estate calculators
Underwriting helpers for rental yield, hosts, and active investors. More property math on the way.
These calculators model real estate investment decisions from initial underwriting through hold-period analysis. The Airbnb short-term rental profit calculator factors in seasonal occupancy, platform fees, cleaning fees, and fixed operating costs to produce net profit and annual yield. The house flipping calculator models rehab line items, interest carry on a hard money loan, purchase closing costs, and sale-side frictions against an ARV to show gross margin and return on invested capital.
The BRRRR strategy simulator steps through all five phases — buy, rehab, rent, refinance, repeat — to show how much capital you recover from a cash-out refi, the resulting DSCR, and post-refi cash flow. The 1031 exchange calculator models boot, the 25% depreciation recapture rate, and like-kind swap requirements to estimate how much capital gains tax is deferred. Cap rate and rental yield tools cover the standard income-property metrics. All inputs stay in your browser.
