Glossary Terms

NOI
Net operating income. Annual property income after vacancy, credit loss, operating expenses, and reserves, before debt service and taxes.
DSCR
Debt service coverage ratio. NOI divided by annual debt service, used to test whether property income covers the mortgage payment.
LTV
Loan-to-value. Loan amount divided by property value, used to measure collateral leverage.
CLTV
Combined loan-to-value. Total debt from all loan layers divided by property value.
Debt Yield
NOI divided by loan amount. A lender income-cushion metric that ignores interest rate, amortization, and appraised value.
Cap Rate
Capitalization rate. NOI divided by property value or purchase price, used to compare unlevered asset yield.
Loan Constant
Annual debt service divided by loan amount. It converts loan proceeds into annual payment burden.
Amortization
The schedule over which principal is repaid. Longer amortization usually lowers annual debt service and improves DSCR.
Balloon Payment
The remaining loan balance due at maturity when the loan term is shorter than the amortization schedule.
Replacement Reserves
Funds set aside for future capital replacements. Lenders may deduct reserves when calculating underwritten NOI.
Binding Constraint
The loan sizing test that produces the lowest maximum loan amount. It controls final proceeds.
Annual Debt Service
