How To Use It

Four fields. Four answers.

Each input maps to something a lender will actually ask. Get all four right before you submit.

01

Price and loan

Purchase price and loan amount drive everything downstream. Move the LTV slider to see what 60% vs 75% does to the rest of the deal.

02

Rate and structure

Rate, maturity, amortization. Flip on interest-only if the deal calls for it — the calc handles IO-then-amortize without you doing extra math.

03

Coverage

Drop in first-year NOI. DSCR is the line that decides if lenders quote. Below 1.20x is a no. Above 1.25x and you’re in business.

04

Print and send

Open the amortization schedule under the chart and print it. Drop it into the memo or send it with the term sheet request.

Key Terms

CRE, plainly defined.

Definitions written the way you'd hear them on a deal call — not the way they're written in a textbook.

Debt-Service Coverage Ratio. NOI divided by annual debt service. Most stabilized deals need 1.20–1.30x to attract real quotes. Below 1.0 and the property doesn’t cover the loan.
