Why these sheets
Most free calculators quietly flatter the deal: vacancy at 0%, no repairs, no CapEx reserve. Ours do the opposite — the sample deal pre-loaded in the rental analyzer actually fails its own test (cash flow −$294.60/mo, DSCR 0.78), because that is what an honest screening tool is for. Read the method in our cap rate guide: formulas, a fully worked example, and the mistakes that make deals look better than they are.
Both tools are spreadsheets — no subscription, no account, works offline in Excel or Google Sheets. Edit only the yellow cells; everything else is formulas, and the flip workbook even verifies its own math on 8 built-in checks.
