The financial results come from deterministic formulas — never a black box and never a guess. Every estimate shows its source, defaults are clearly flagged, and you can override anything. The verdict is a documented rule, so you always know why.
Why a verdict, not just numbers?
A page full of metrics still leaves you asking "so… should I buy it?" RentalRundown compares the results against your targets and a conservative stress case, then makes the call — buy, negotiate, investigate, or pass — with the reasons in plain language.

Is RentalRundown really free?
Yes. The complete analysis — cash flow, returns, the verdict, and the maximum offer price — is free with no account, no download, and no paywall. Most full-featured analysis software charges a subscription; this doesn't.
Do I need to create an account?
No. You can analyze as many properties as you like without signing up. Nothing you enter is required to leave your browser.
How accurate is the analysis?
The math is exact and deterministic — the same inputs always produce the same results, using standard real-estate formulas. Accuracy then depends on your inputs: realistic rent, taxes, insurance, and vacancy. Every assumption is visible and editable so you can match your local reality, and estimated defaults are flagged.
Can I use it on a property I found on a listing site?
Yes. Grab the asking price and rent estimate from any listing, enter them along with your financing, and you'll have a full analysis and a verdict in under a minute.
Is this financial advice?
No. RentalRundown provides educational estimates to help you think through a decision. Verify every figure and consult licensed professionals before making an offer.
