Answer for investors
What is the debt service coverage ratio?
The debt service coverage ratio (DSCR) compares a rental property's net operating income with the mortgage payment on that property. Real estate investors use it to see whether the rent covers the debt before a broker reviews a business-purpose loan. The ratio is an estimate, not a loan approval.
How do you calculate DSCR?
DSCR equals net operating income divided by debt service. Net operating income is gross rent minus operating expenses such as taxes, insurance, HOA dues, management, and maintenance. Debt service is the principal-and-interest payment used in the scenario. Count taxes and insurance only once, either in expenses or inside the payment.
DSCR = net operating income / debt service
What is an example of a 1.08 DSCR?
A property with $3,500 gross monthly rent and $800 of operating expenses has $2,700 of net operating income. Divided by $2,500 of monthly debt service, the DSCR is 1.08, which is $200 of monthly cushion. Many investor programs look for about 1.25. Ratios under 1.00 usually have fewer options, and every lender sets its own minimum.
