Understanding Mortgage Prequalification

Mortgage prequalification gives you an estimate of how much you can borrow based on your financial information. This helps you understand your budget before you start house hunting.

Key Factors in Prequalification
  • Debt-to-Income Ratio (DTI): Your total monthly debt payments divided by gross monthly income
  • Credit Score: Affects interest rates and loan approval odds
  • Down Payment: Typically 3-20% of home price, affects loan terms
  • Employment History: Stable income source for at least 2 years preferred
  • Cash Reserves: Funds for closing costs and emergency reserves
Types of Mortgage Loans
  • Conventional: Not government-backed, typically requires 5-20% down
  • FHA: Government-backed, allows 3.5% down payment
  • VA: For veterans, often allows 0% down payment
  • USDA: For rural properties, may allow 0% down
  • Jumbo: For loan amounts above conforming loan limits
Monthly Payment Components
  • Principal: Amount going toward loan balance
  • Interest: Cost of borrowing money
  • Property Taxes: Local government taxes on property
  • Insurance: Homeowner's insurance to protect the property
  • PMI: Private mortgage insurance if down payment < 20%
  • HOA: Homeowner's association fees if applicable
Improving Your Qualification
  • Increase Income: Higher income allows for larger loan amounts
  • Reduce Debt: Lower monthly obligations improve DTI ratio
  • Improve Credit Score: Better rates and terms
  • Save More: Larger down payment reduces loan amount and PMI
  • Consider Different Loan Types: FHA, VA, or USDA may offer better terms
