Why I built DealQuanta

I'm the founder of DealQuanta. I built it because I kept underwriting rental deals the same slow way everyone does — a tangle of spreadsheet tabs I'd copied from someone else, never quite sure the formulas were right, and nothing I'd want to put in front of a client or a lender.

DealQuanta is the tool I wanted: type in a property's numbers and get a complete, correctly-calculated model — NOI, cap rate, cash-on-cash, DSCR, a 10-year pro forma with IRR — plus a clean PDF you can actually hand to an investor. The math is the part I cared about most, so the underwriting engine is covered by an automated test suite and the scoring methodology is written out in plain language. No black box.

I want to be straight about what this is and isn't. DealQuanta is a software analysis tool, not financial advice. It computes the numbers from the assumptions you give it. It doesn't know your market, your financing, or your risk tolerance, and it never moves money or touches your bank. The outputs are estimates to help you think — the decision is always yours, ideally with your own professionals in the loop.

It's also early. If something is wrong, confusing, or missing, I genuinely want to hear it — that feedback is how the product gets better.
