Understanding Mortgages
A mortgage is a loan used to purchase real estate, secured by the property itself. Understanding how mortgages work helps you make informed decisions about the biggest purchase most people ever make.
Mortgage Payment Formula
M = P Γ [r(1+r)βΏ] / [(1+r)βΏ - 1]
Where:
- M = Monthly payment
- P = Principal (loan amount)
- r = Monthly interest rate
- n = Total number of payments
Components of Monthly Payment (PITI)
- Principal: Portion that reduces your loan balance
- Interest: Cost of borrowing money
- Taxes: Property taxes (varies by location)
- Insurance: Homeowners insurance and PMI if applicable
Example Calculation
$400,000 home, 20% down, 6.5% rate, 30-year term:
- Loan amount: $320,000
- Monthly P&I: $2,022
- Estimated taxes: $400
- Insurance: $150
- Total monthly: ~$2,572
Loan Term Comparison
| 15-Year | 30-Year | |
|---|---|---|
| Monthly Payment | Higher | Lower |
| Interest Rate | Lower | Higher |
| Total Interest Paid | Less | More |
| Builds Equity | Faster | Slower |
$300,000 Loan at 6.5% vs 6.0%
- 15-year: $2,613/month, $170,000 total interest
- 30-year: $1,896/month, $382,000 total interest
Down Payment Impact
- 20%+ down: No PMI required
- 10-19% down: PMI until 20% equity
- 3-5% down: Higher PMI, more interest over time
Tips for Better Rates
- Improve credit score (aim for 740+)
- Save larger down payment
- Compare multiple lenders
- Consider buying points
