Loan-to-Value Ratio
The loan-to-value ratio (LTV) expresses the mortgage loan amount as a percentage of the appraised property value. It is a primary risk metric used by lenders to determine maximum loan proceeds and pricing.
LTV is one of the three main constraints that lenders use to size commercial real estate loans, alongside DSCR and debt yield. A lower LTV means the borrower has more equity at risk, which provides a larger cushion for the lender in the event of default. Most conventional commercial lenders cap LTV at 65-75% for stabilized properties, though some bridge and construction lenders may go higher for qualified borrowers.
The relationship between LTV and interest rates is direct: higher leverage means higher risk, which means higher borrowing costs. A loan at 55% LTV might carry a rate 50-75 basis points lower than the same loan at 75% LTV. This creates a tradeoff for investors between maximizing leverage to boost equity returns and minimizing borrowing costs. The optimal leverage point depends on the investor's return targets, risk tolerance, and the interest rate environment.
LTV also determines recourse requirements. Many lenders offer non-recourse financing (where the loan is secured only by the property) at lower LTVs, but require personal guarantees or partial recourse at higher leverage levels. Understanding these thresholds is critical during deal structuring because recourse obligations can significantly affect the risk profile of an investment for the individual sponsor.
Formula
Worked Example
A lender appraises a medical office building at $4,200,000 and offers a loan at 70% LTV. Maximum loan amount = $4,200,000 x 0.70 = $2,940,000. The borrower must contribute at least $1,260,000 in equity plus closing costs.

Debt Service Coverage Ratio
The debt service coverage ratio (DSCR) measures a property's ability to cover its annual debt obligations from its net operating income. Lenders use DSCR as a primary underwriting metric to assess loan risk.
Debt Yield
Debt yield is the ratio of a property's net operating income to the total loan amount, expressed as a percentage. It measures a lender's return on investment in a worst-case scenario and is independent of interest rate or amortization terms.
Underwriting
Underwriting in commercial real estate is the analytical process of evaluating a property's financial viability, risk profile, and return potential to determine an appropriate acquisition price or loan amount.
