How Mortgages Work
A mortgage is a loan used to buy real estate. The lender provides funds to purchase the property, and you repay the loan (principal) plus interest over a set term, usually 15–30 years. Each payment reduces your balance and covers interest.
- Principal: The amount borrowed to buy the home.
- Interest Rate: The yearly cost to borrow, expressed as a percentage.
- Term: The length of the loan, typically 15 or 30 years.
- Down Payment: The upfront amount you pay, reducing the loan size.
- Amortization: Paying off the loan in equal installments over time.
- Escrow: An account for property taxes and insurance payments.
How Monthly Payments Are Calculated
Monthly payments are based on the loan amount, interest rate, and term. The standard formula for a fixed-rate mortgage is:
- P = Monthly payment
- L = Loan amount (principal)
- r = Monthly interest rate (annual rate / 12 / 100)
- n = Number of monthly payments (term)
Example: $300,000 loan, 4% interest, 30 years
Monthly Payment: $1,432
Types of Mortgages
Common Mortgage Types
Fixed-Rate Mortgages
- Interest rate stays the same for entire term
- Predictable monthly payments
- Higher initial rates than ARMs
- Best for long-term homeowners
- 15, 20, or 30-year terms common
Adjustable-Rate Mortgages (ARMs)
- Rate may change after initial period
- Lower initial rates than fixed
- Payments can increase over time
- Good for short-term ownership
- 3/1, 5/1, 7/1 ARMs common
Government-Backed Loans
- FHA Loans: Lower credit requirements, 3.5% down payment, mortgage insurance required
- VA Loans: For veterans and service members, often no down payment required
- USDA Loans: For rural areas, low-income borrowers, often no down payment
- Conventional Loans: Not government-backed, typically require 5-20% down
Down Payment Considerations
Down Payment Impact
Larger Down Payment
- Lower monthly payments
- Less total interest paid
- May avoid PMI
- Better interest rates
- More equity upfront
Smaller Down Payment
- Lower upfront costs
- Higher monthly payments
- PMI may be required
- More total interest paid
- Less equity initially
Private Mortgage Insurance (PMI)
- Required when down payment is less than 20%
- Protects the lender, not the borrower
- Typically 0.5% to 1% of loan amount annually
- Can be removed when equity reaches 20%
- FHA loans have MIP (similar to PMI)
- VA loans don't require PMI
Tips for Home Buyers
- Check your credit score and improve it if possible before applying
- Save for a larger down payment to reduce your loan and interest
- Compare offers from multiple lenders
- Consider total costs: taxes, insurance, HOA fees, and maintenance
- Get pre-approved before house hunting
- Understand closing costs (typically 2-5% of home price)
- Consider your long-term plans when choosing loan terms
- Factor in potential rate increases with ARMs
Frequently Asked Questions (FAQ)
Q: How much should I put down on a house?
A: 20% is common and avoids PMI, but some loans allow as little as 3% down. Consider your financial situation and long-term goals when deciding.
Q: What is PMI?
A: Private Mortgage Insurance is required if your down payment is less than 20%. It protects the lender, not you, and adds to your monthly payment.
Q: Can I pay off my mortgage early?
A: Yes, but check for prepayment penalties. Early payoff saves on interest and builds equity faster. Consider refinancing if rates drop significantly.
Q: What is an escrow account?
A: An account managed by your lender to pay property taxes and insurance on your behalf. The lender collects these costs with your monthly payment.
Q: Should I choose a 15 or 30-year mortgage?
A: 15-year loans have higher payments but less total interest. 30-year loans have lower payments but more total interest. Consider your budget and goals.
