Example Calculation
Let’s assume:

- Down Payment = 20% ($120,000)
- Loan Amount = $480,000
- Interest Rate = 6% annually
- Loan Term = 30 years
Step 1: Monthly interest rate
6% ÷ 12 = 0.5% per month
Step 2: Loan term
30 years = 360 months
Step 3: Monthly payment result
Approximate mortgage payment = $2,878 (principal & interest only)
After adding taxes and insurance:
- Property Tax (~1.1%) ≈ $550/month
- Insurance ≈ $150/month
Total Monthly Cost:
≈ $3,578/month
