Tanner Dean Real Estate

A good deal and a bad deal can look identical from the curb. The difference is in the numbers — and the numbers are only as good as the assumptions behind them. Before you write an offer on a rental or a commercial building, you want to know what it actually returns once vacancy, expenses, and debt service are accounted for.

This analyzer runs the core metrics investors live by. Toggle between two modes:

  • Residential (1–4 unit rentals) — purchase price, financing terms, rent, and operating assumptions in, and out comes your monthly cash flow, cap rate, cash-on-cash return, the 1% rule check, and debt-service coverage ratio.
  • Commercial (5+ unit, retail, office, mixed-use) — gross scheduled income, vacancy, and operating expenses drive NOI, cap rate, DSCR, cash-on-cash return, and annual cash flow.

Plug in real numbers and you'll see in seconds whether a deal pencils or whether it's leaning on optimistic assumptions. Use it to screen properties fast and focus your time on the ones worth a closer look.

When a deal looks promising, the next step is financing — and Tanner Dean works with ALLIANCE Credit Union on both the residential and commercial sides. Run your analysis below, and we'll connect you with the right lender to pressure-test it.
