Before determining how much you can borrow for a mortgage, focus first on how much house you can actually afford. Lenders often approve loans larger than what's financially comfortable for borrowers.

Key Factors Affecting Your Mortgage Amount:

• Debt-to-Income Ratio (DTI): Lenders typically want total debts under 36% of monthly income • Down Payment: Larger down payments improve loan terms and reduce monthly payments • Credit Score: Most lenders require minimum 620, affects interest rates • Loan-to-Value Ratio (LTV): Relationship between loan amount and home value

Important Considerations:

• Follow the 28% Rule: Monthly mortgage payments shouldn't exceed 28% of pre-tax income • Account for Additional Costs:

  • Down payment (typically 3-20%)
  • Closing costs (2-6% of home price)
  • Private Mortgage Insurance (PMI) if down payment is less than 20%
  • Property taxes and insurance
  • Home maintenance and repairs

Mortgage Term Options:

• 30-Year Fixed: Lower monthly payments but more total interest • 15-Year Fixed: Higher monthly payments but less total interest • Adjustable-Rate (ARM): Lower initial rate, changes after fixed period

How to Qualify for Better Terms:

  1. Increase down payment amount
  2. Reduce existing debt
  3. Improve credit score
  4. Consider a starter home instead of forever home
  5. Compare offers from multiple lenders

Remember: Focus on what's affordable for your budget rather than the maximum amount you can borrow. Consider all homeownership costs when determining your comfortable price range.
