Clear math for considered decisions.

RentDealCheck exists to make the financial side of a rental property decision easier to inspect. The calculators show their assumptions, keep operating performance separate from financing, and explain what each output does and does not mean.

How we work

We favor plain language, visible formulas and conservative defaults over sales pressure. The guides explain the mechanism behind a metric, so you can understand it instead of memorizing a benchmark. The formulas are standard, and the math is checked against hand-computed examples.

How the site is funded

The tools are free to use with no account. The site is supported by advertising and by links to services we think are relevant, some of which pay us a commission if you sign up. Compensation never changes a calculator’s result. Read the affiliate disclosure for details.

What this is not

The tools provide educational estimates, not investment, tax, legal, lending or insurance advice. A real purchase requires local research, a property inspection, verified costs and professional judgment.
