🏠Why Accurate Affordability Analysis Matters

"How much house can I afford?" is every prospective homebuyer's first question. But making decisions based solely on loan approval amounts can lead to financial disaster.

💡 Real Example

John earns $80,000 annually and got approved for a $400,000 loan, but...
Comfortable affordability: $300,000 (25% of monthly income)
Bank approval limit: $400,000 (35% of monthly income)
Difference: $100,000 - This difference determines financial stability!

📊DTI Ratio: The Key Affordability Metric

What is DTI (Debt-to-Income)?

Monthly Total Debt Payments ÷ Monthly Gross Income × 100. The lower this ratio, the more financially secure you are.

Calculation Example

Monthly income: $5,000, Existing debt payments: $1,000, Mortgage payment: $1,500

DTI = ($1,000 + $1,500) ÷ $5,000 × 100 = 50%

✅ Safe Zone (25% or less)

  • • Plenty of financial breathing room
  • • Can build emergency fund
  • • Can invest in other goals
  • • Safe from interest rate increases

⚠️ Caution Zone (25-35%)

  • • Manageable but tight
  • • Be cautious with additional debt
  • • Emergency fund essential
  • • Need income growth plan

🚨 Danger Zone (35%+)

  • • High financial stress
  • • Difficult to handle emergencies
  • • Vulnerable to rate increases
  • • Consider delaying purchase

💸Hidden Costs: More Expenses Than Expected

🧮How to Calculate Affordability

📐 Basic Calculation Formula

1. Calculate Monthly Payment Capacity

Monthly Payment Capacity = (Monthly Income × Target DTI Ratio) - Existing Debt Payments

2. Calculate Loan Amount

Loan Amount = Monthly Payment ÷ Monthly Payment Rate (determined by interest rate and term)

3. Total Purchase Price

Purchase Price = Loan Amount + Down Payment - Initial Costs

💰 Real Calculation Example

Conditions: Monthly income $6,000, no existing debt, $100,000 down payment, target DTI 25%

Monthly payment capacity:$6,000 × 25% = $1,500
Loan amount (3.5%, 30 years):~$330,000
Initial costs (5%):~$22,000
Total affordable price:~$410,000
