Frequently asked questions
Do all lenders allow this?
Most do, though some charge for a formal biweekly plan — you can replicate it free by paying 1/12 extra monthly.
Is it better than investing the difference?
If your mortgage rate exceeds your expected after-tax investment return, paying down wins.
