How accurate are online mortgage and affordability calculators?
Online mortgage and affordability calculators give you a useful starting point, but they rely on assumptions that may not match your actual situation. They often use generic estimates for property taxes, insurance, HOA dues, and interest rates, and don't account for your full debt profile, credit score, or down payment source. Lenders calculate affordability based on debt to income ratio, credit history, and loan program rules that a calculator can't capture. Use them for rough budgeting, but get pre-approved with an actual lender to know what you truly qualify for before you start shopping seriously.
