DSCR planning: vacancy, reserves, and property expenses

Considering a rental property and hearing the term DSCR? Start with the property’s cash-flow plan—not just the projected rent.

First, model vacancy. A tenant may move out, a lease may start later than expected, or a unit may need repairs between occupants. Treat that gap as a real cash need instead of assuming every month is fully collected.

Next, list the property expenses. Depending on the property, that can include principal and interest, property taxes, insurance, HOA dues, utilities, management, routine maintenance, and larger replacement items. Separate recurring bills from occasional repairs so the monthly picture does not look better than the annual one.

Then build reserves. Keep funds for vacancies, deductibles, repairs, and other surprises after closing. Reserves are not the same as projected profit, and a lender’s reserve or rental-income rules may differ from your personal safety margin.

Important notes

• This is general education, not tax, legal, investment, or individualized mortgage advice. DSCR terminology, calculations, eligible properties, documentation, reserves, and rental-income treatment vary by lender, program, transaction, jurisdiction, and borrower profile.
• The cited agency guides are not a promise that any particular lender or product will use the same method. A lender must review the complete application and property; no approval, rate, terms, closing speed, or product availability is represented.
