What is CRE underwriting?

Underwriting in commercial real estate means testing whether a deal works under your assumptions — purchase price, rent, vacancy, OpEx, and debt — before you write an LOI. The goal is clear returns: NOI, cap rate, DSCR, cash-on-cash, and IRR. CREflow’s free underwriting calculator replaces fragile spreadsheets for office, retail, industrial, multifamily, and mixed-use screening.

Why use a commercial real estate underwriting calculator?

Brokers and investors need a fast way to underwrite an offering before diligence. A CRE underwriting calculator turns asking price, rent per square foot, vacancy, OpEx, and loan terms into clear returns — so you can pass, pursue, or renegotiate with confidence.

CREflow’s free underwriting tool is built for office, retail, industrial, multifamily, and mixed-use acquisitions. Enter deal setup once, then iterate interest rate, down payment, rehab, and exit assumptions without rebuilding a spreadsheet.

Core CRE underwriting metrics explained

NOI (net operating income) is effective revenue minus operating expenses — the foundation of cap rate and DSCR. Cap rate divides NOI by purchase price (or all-in basis) to screen yield. DSCR compares NOI to annual debt service for lender risk. Cash-on-cash shows annual cash flow versus cash invested. IRR folds hold-period cash flows and sale proceeds into a single return.
