5 Surprising Facts About Paying Off Mortgages Early
When does it make sense to pay off a mortgage ahead of schedule? Here are some lesser-known tidbits.
1.Your Credit Score Might Temporarily Dip
Paying off a large debt can lead to a short-term decrease in your credit utilization, but it recovers quickly once everything updates.
2.Some Lenders Waive IRD on Special Occasions
A few lenders have holiday or promotional windows where they reduce or waive IRD penalties if you meet certain conditions.
3.Mortgage 'Shortening' Beats Refinancing Sometimes
Instead of a refinance, simply paying a lump sum or making bigger payments could save more interest if your existing rate is already favourable.
4.Psychological Benefits are Real
Homeowners often report feeling less stress when they're free of mortgage debt, even if the math doesn't always show huge savings.
5.Ask About Porting the Mortgage
In some regions, you can 'port' your existing mortgage to a new home, preserving your current rate and terms, thus avoiding penalties entirely.
