How Mortgage Qualification Works

Lenders use your debt-to-income ratio (DTI) to determine how much you can borrow. Most lenders prefer a DTI of 36% or less, though some allow up to 43% or higher with compensating factors.

The 28/36 rule is common: spend no more than 28% of gross income on housing and 36% on total debt. This calculator uses these guidelines to estimate your qualification amount.

Frequently Asked Questions

How much mortgage can I qualify for?
Most borrowers qualify for 3-4 times their annual income, depending on debts. With $75k income and minimal debt, you might qualify for $225k-$300k. High existing debt reduces this significantly. Use this calculator for your specific situation.
What is the debt-to-income ratio?
DTI is your monthly debt payments divided by gross monthly income. Lenders use two ratios: front-end (housing only, max 28%) and back-end (all debt, max 36%). Some loans allow up to 50% DTI with strong credit and reserves.
Does pre-qualification guarantee a loan?
No, pre-qualification is an estimate based on self-reported information. Pre-approval is stronger—lender verifies income, credit, employment. Final approval requires appraisal, title search, and underwriting review of all documentation.
Why did my qualification amount change?
Qualification depends on income, debts, credit score, interest rates, and loan program. Any change affects results. Rising rates reduce buying power. Paying off debt increases it. Different lenders may calculate differently too.
Should I get pre-qualified before house hunting?
Yes! Pre-qualification shows sellers you're serious, helps you focus on affordable homes, and speeds up the buying process. It's usually free and takes minutes. Some sellers won't consider offers without pre-qualification letters.
What if I don't qualify for enough?
Options: pay down debt to improve DTI, increase down payment, add co-borrower, improve credit score for better rate, look at lower-priced areas, consider FHA/VA loans with more flexible requirements, or wait and save more.
Do lenders use gross or net income?
Gross income (before taxes). Lenders use pre-tax income to calculate DTI ratios. This includes base salary, bonuses, commissions, alimony, child support, and other regular income sources. Part-time and self-employment income usually needs 2-year history.
What debts count in DTI calculation?
Recurring monthly obligations: car loans, student loans, credit card minimums, personal loans, child support, alimony. Not included: utilities, insurance (except mortgage), groceries, phone bills, or other living expenses.
Can I qualify with bad credit?
FHA loans allow scores as low as 580 with 3.5% down (500-579 needs 10% down). Conventional loans typically need 620+. Lower scores mean higher rates and stricter DTI requirements. Work on credit first for better terms.
How long does pre-qualification last?
Pre-qualification letters typically valid 60-90 days. Rates change, your situation may change. If you don't find a home in that window, you'll need updated letter. Employment or credit changes may require re-qualification.
Does rental history help qualification?
Some lenders consider 12+ months of on-time rent payments as compensating factor, especially for first-time buyers with limited credit. Not all lenders use this. Document with cancelled checks or bank statements showing consistent payments.
Should I max out my qualification amount?
Not necessarily. Just because you qualify for $400k doesn't mean you should spend that much. Consider other goals—retirement savings, emergency fund, lifestyle. Being "house poor" stresses finances. Many experts recommend staying below max qualification for comfort.
