How to read this tool: Construction loans size against TWO constraints: LTC (loan-to-cost, max 65-70% typical) AND LTV (loan-to-stabilized-value, max 55-65% typical). The lender takes the LOWER of the two. The construction-period interest is capitalized into the loan principal (interest reserve), funded from the same loan. The sponsor often must personally guarantee completion.

What this tool is for

Construction lending is structurally different from acquisition lending. The lender is funding draws against work-in-place, with monthly inspection draws by an independent monitor. Sponsor recourse for completion is standard. The HVCRE regulatory category amplifies capital requirements on construction loans with insufficient sponsor equity. This tool sizes the maximum loan.
