About this tool
1% & 2% Rule Rental Screener is a free, in-browser tool that runs a rental property through the two best-known quick screens investors use to judge cash-flow potential. Enter the purchase price, an optional rehab cost and the monthly rent, and it reports the rent-to-price ratio plus a pass or fail against both the 1% and 2% rules. Everything is calculated on your device — nothing is uploaded.
The total cost is purchase price + rehab, and the ratio is monthly rent ÷ total cost × 100. The 1% rule passes when monthly rent is at least 1% of the total cost; the 2% rule (a much tougher bar) passes at 2% or more. The tool also shows the exact rent you would need to hit each threshold: 1% of cost and 2% of cost.
Use it as a first-pass filter, not a verdict: a property that clears the 1% rule is more likely to cash flow, but the rules ignore taxes, insurance, interest rates and vacancy. The 2% rule is rare in most markets today. Treat a pass as a reason to run a full analysis, and a fail as a reason to negotiate the price or move on.
