Calculations used to determine if a borrower can qualify for a mortgage. They consist of two separate calculations: a housing expense as a percent of income ratio and total debt obligations as a percent of income ratio.
Qualifying ratios
Guidelines applied by lenders to determine how large a loan to grant the homebuyer. The debt-to-income ratio is your current monthly debt on loans and credit cards divided by your gross income. The housing-to-income ratio is your new housing payment divided by your gross income.
