Understanding DTI Ratios

Lenders use DTI ratios to assess your ability to manage monthly payments and repay debts. Understanding these ratios helps you prepare for mortgage qualification.

Front-End DTI

Housing costs (rental/mortgage, property tax, HOA fees, insurance) divided by monthly gross income. This measures how much of your income goes toward housing (also called PITI - Principal, Interest, Taxes, Insurance).

28% or less recommended for conventional loans (up to 47% for FHA)

Back-End DTI

All monthly debt payments (housing + credit cards + loans) divided by monthly gross income. This is the primary qualification metric used by lenders.

43% or less recommended (up to 50% for conventional, up to 57% for FHA). VA doesn't set a maximum limit but suggests additional financial scrutiny on borrowers with a ratio greater than 41%.

Tips to Improve Your DTI

• Pay down existing debts before applying for a mortgage

• Increase your income through raises, bonuses, or side income

• Avoid taking on new debt before applying for a mortgage

• Consider a larger down payment to reduce loan amount

• Look for properties with lower property taxes or HOA fees
