Frequently asked questions

Gross (before-tax) monthly income from all sources: salary, overtime, bonuses (averaged over the last 2 years), freelance income, rental income, investment income and, if applicable, alimony or child support received. Lenders may discount income they consider unstable.

Either pay off debt (which lowers the numerator) or increase income (which raises the denominator). Paying off a car loan or credit card reduces monthly obligations immediately. Adding a co-borrower with income can also improve the ratio — lenders assess the combined income and debts of both applicants.
