Most people have heard the terms GDS and TDS, but very few actually know what they mean or how they affect what you can qualify for.
Think of it this way:
GDS (Gross Debt Service) looks at your housing costs onlyāyour mortgage payment, property taxes, heating and, if applicable, condo fees.
TDS (Total Debt Service) takes it a step further by adding your other monthly obligations like car loans, credit cards, lines of credit and student loans.
These ratios are one of the biggest factors lenders use when deciding how much theyāll approve you for. The good news? Different lenders have different guidelines, and sometimes thereās more flexibility than people realize.
Thatās why it pays to understand your options before assuming you wonāt qualify.
