About DealGauge

DealGauge builds honest, no-nonsense analysis tools for everyday real estate investors. Many quick calculators leave out the costs that decide whether a rental actually pays. DealGauge is built to include them, and to tell you plainly when a deal does not work, including when to walk away.

What we make

A free calculator that grades any rental deal, and a paid toolkit of spreadsheets, guides, and research prompts that help buy-and-hold and short-term investors underwrite a property before they offer. Everything is a one-time download you own, built for Excel and Google Sheets. No subscriptions, no logins, no advice, just clear math you can audit yourself.

How the grade is calculated

The DealGauge grade is a transparent 0-to-100 score built from four things that actually decide whether a rental makes money:

Cash flow after every real expense, including vacancy, maintenance, capital expenditures, and management
Cash-on-cash return on the total cash you invest, reserves included
Debt coverage, both after all costs and on the gross-rent basis lenders actually use
Cap rate against your target

In the paid model every threshold is yours to edit, so the grade reflects your buy box, not ours. Nothing is hidden: every formula is visible and every assumption is a labeled cell you can change.

Our one bias: toward caution. We use full reserves by default, we do not assume rents rise, and we show the after-tax picture without pretending you can always use paper losses. If a deal only works on optimism, our tools will say so.

Where our market data comes from

Our market reports summarize published, freely available third-party data, with the source and date shown on every figure. We draw on public releases such as the U.S. Census Bureau, HUD, the Federal Reserve (FRED), Freddie Mac's mortgage-rate survey, and public research indexes. We report figures as of a stated date and refresh them each quarter. We do not resell anyone's proprietary data.

The limits of these tools

DealGauge is educational software, not advice. Every number it produces is an estimate based on the assumptions you enter, and estimates can be wrong. Real estate is local, cyclical, and full of details a spreadsheet cannot see. Always verify rents, expenses, taxes, and rules against primary local sources, and consult a qualified professional, an accountant, attorney, lender, or licensed agent, before you buy, sell, or finance any property.
