To afford this mortgage
📊 Affordability Analysis: Your mortgage payment should be less than 28% of your gross monthly income. Total debt payments (including mortgage) should stay below 36% for comfortable budgeting.
⚠️ Refinancing Strategy: Consider refinancing when rates drop 1% or more below your current rate. The closing costs (2-5% of loan) should be recovered within 24 months through payment savings.
✅ Investment Comparison: If your mortgage rate is lower than expected investment returns (typically 7-10% for stocks), it may be better to invest extra money rather than paying down the mortgage faster.

Break-Even Analysis

🔄 Break-even Point: You'll need to stay in this home for at least 5.2 years to recover closing costs and break even vs. renting. This considers appreciation, tax benefits, and transaction costs.
📅 5-Year Projection:
  • Total equity built: $48,000
  • Total interest paid: $98,605
  • Total tax deductions: $19,721
  • Net housing cost: $78,884
📈 Appreciation Impact: If your home appreciates at 3% annually (national average), in 5 years it will be worth $463,710, giving you $111,710 in total equity (original down payment + appreciation + principal paid).

Risk Factors

  • Interest rate increases if you have an adjustable-rate mortgage (ARM)
  • Property taxes typically increase 3-5% annually in most areas
  • Maintenance costs average 1-3% of home value annually ($4,000-$12,000/year)
  • Income stability and job security should support the mortgage commitment
