Rental deal analyzer · full underwrite, in the open
Run the deal like a lender,
not like a listing agent.
Cash flow, cap rate, cash-on-cash, DSCR, the 1% test, break-even occupancy, and what amortization alone earns you in five years. Every reserve is in the math and every assumption is editable. One more thing, because it matters: this page does no analysis on a server. Your numbers never leave your browser.

How to read the verdict
Strong
Positive cash flow with cash-on-cash at 8%+ and DSCR at 1.2+, the coverage bar lenders underwrite to. A deal that pays you and would survive a refinance conversation.
Workable
Pays you something after real reserves but misses a strong bar. Usually fixable: price, down payment, or rent is doing too little work. Negotiate before you settle.
Thin or negative
Under $100 a month of margin, or below zero. The market is full of these at asking price. The tool will not rescue them with an appreciation guess.
What we never count
Appreciation, rent growth, and tax effects. They can help, but a tool that bakes them in is guessing on your behalf. Reserves and amortization are the honest floor.
