About this calculator

Is it really free? What's the catch?

Yes, and there's no catch. No account, no report limits, no paywall. Popular alternatives now lock rental analysis or saved reports behind a paid plan; this one keeps everything client-side in your browser, so unlimited use costs nothing to run.

How do shareable reports work?

Every input is encoded into the page URL as you type. Hit Copy share link and send it to a partner, lender, or agent — they'll see the exact same analysis, no login needed. Bookmark the link to "save" a deal.

What do the numbers mean?

NOI is income minus operating expenses (before the mortgage). Cap rate is NOI ÷ purchase price. Cash-on-cash is annual cash flow ÷ total cash invested. DSCR is NOI ÷ annual debt service — lenders typically want ≥ 1.2. The 1% rule flags whether monthly rent is at least 1% of the purchase price — a quick screen, not gospel.

Is this financial advice?

No. It's arithmetic on your assumptions. Verify taxes, insurance, and rents locally before you buy anything.
