How it works
rental property mortgage analysis takes your inputs and produces monthly payment, monthly cash flow. Analyze mortgage options for rental properties including DSCR and cash flow impact. You provide 4 inputs: Property Price (currency, in dollars) (default: 350000 dollars); Down Payment % (percent, in percent) (default: 25 percent); Mortgage Rate % (percent, in percent) (default: 7.5 percent); Monthly Rent (currency, in dollars) (default: 3000 dollars). The calculator returns 2 outputs: Monthly Payment (the primary result); Monthly Cash Flow (a secondary output). Investment calculations rest on a few variables — principal, return rate, time, and compounding — but their interaction is non-linear enough that intuition alone gets the answer wrong more often than not. This tool runs the real formula with your inputs and shows the numbers that matter, not the rounded approximations from a textbook. With the default values, monthly payment is computed from the interaction of every input field — change any one of them and the result updates immediately, so you can stress-test different scenarios without re-entering the whole form. Adjust the inputs to match your real financial situation. The defaults are realistic starting points, but every person's circumstances differ — your actual income, expenses, rates, and timelines will produce a different answer. Use the tool iteratively: start with the defaults, then change one variable at a time to see which factor has the largest impact on your outcome.Tips
- Start with the default values to see a baseline result, then change one input at a time to understand which factor matters most for your outcome.
- Replace every default with your actual number — estimates and rules of thumb produce estimates, not answers. Pull your real figures from pay stubs, statements, or account dashboards.
- Use a conservative return rate (5-6% rather than the historical 10%) for planning purposes. Markets have long flat stretches, and planning on the average sets you up for a shortfall.
Frequently asked questions
Can I qualify for a rental mortgage?
$350K, 25% down: $262K loan at 7.5% = $2,195/mo. DSCR: $36K/$26.3K = 1.37. Qualifies (need 1.25+). Cash flow: +$300/mo.
What does the rental property mortgage analysis calculate?
It takes property price, down payment %, mortgage rate %, monthly rent as inputs and computes monthly payment, monthly cash flow. The primary output is monthly payment. Analyze mortgage options for rental properties including DSCR and cash flow impact.
How accurate are the calculator results?
The math is exact — the same formulas a financial professional would use by hand. The precision of the output depends entirely on how realistic your inputs are. Use your actual numbers rather than estimates when possible. The defaults are reasonable starting points, but your real income, rates, and timeline will produce a different result.
