Extra Payment Strategies
Bi-Weekly Payments
- Make half-payment every two weeks (26 payments/year)
- Equivalent to 13 monthly payments annually
- Can reduce 30-year mortgage by 5-7 years
- No need to change loan terms with lender
- Small painless way to pay extra
Lump Sum Payments
- Use tax refunds, bonuses, or inheritance
- Specify "apply to principal only" when paying
- Most effective when done early in loan term
- Check for prepayment penalties first
- Consider refinancing for better terms
Mortgage Types Comparison
Fixed-Rate Mortgage
Interest rate remains constant for entire loan term. Predictable payments, easier budgeting, protection against rising rates. Best for long-term homeowners.
Adjustable-Rate Mortgage (ARM)
Fixed rate for initial period (3-10 years), then adjusts periodically. Lower initial rates, but payments can increase significantly. Best for short-term homeowners.
Interest-Only Mortgage
Pay only interest for initial period (5-10 years), then payments increase significantly. Lowest initial payments, but no equity building during interest-only period.
Important Considerations
- Check for prepayment penalties before making extra payments
- Ensure extra payments are applied to principal, not future payments
- Consider opportunity cost - could money earn more elsewhere?
- Factor in mortgage interest tax deductions (consult tax advisor)
- Maintain emergency fund before making extra mortgage payments
- Consider PMI (Private Mortgage Insurance) requirements
Frequently Asked Questions
How do extra payments reduce my mortgage term?
Extra payments directly reduce your principal balance, which reduces the amount of interest charged in subsequent months. Since interest is calculated on the remaining principal, reducing principal early has a compounding effect that significantly shortens your loan term.
Should I pay extra on my mortgage or invest?
Compare your mortgage interest rate to potential investment returns. If your mortgage rate is higher than expected investment returns, paying extra may be better. Also consider factors like risk tolerance, investment time horizon, and whether you itemize deductions for mortgage interest.
What's the best time to make extra payments?
Earlier is better. Extra payments in the first years of your mortgage save the most interest because you're paying down principal before significant interest accrues. A $1,000 extra payment in year 1 saves more than the same payment in year 20.
How do I ensure extra payments go to principal?
Always write "Apply to Principal" on the check/memo line and include a note specifying this. Contact your lender to confirm their process. Some lenders have specific forms or online options for principal-only payments.
