🧠 Additional Insights & Tips

  • Why 20% is Often Ideal:
    A 20% deposit helps avoid Private Mortgage Insurance (PMI), offers better interest rates, and improves loan approval odds.
  • Affordability Rule of Thumb:
    Experts recommend your home should cost no more than 3–5 times your annual income. This tool flags when you exceed this.
  • Debt-to-Income Ratio (DTI):
    Lenders typically prefer a DTI below 36%, with 43% being the maximum allowed by most programs.
  • First-Time Buyer Benefits:
    Many regions offer grants, tax credits, and reduced down payment requirements for first-time buyers—factored into the tool’s suggestions.
