Check if your lender charges for early payments. Sometimes break fees are more than the savings. Ask your bank before paying extra.
I paid down my mortgage using an offset account. You save on interest but can still access the money. It works well if you’re disciplined.
If your mortgage is 6.8%, you save $68 for every $1,000. If your investments return more, go for it. It’s all about where you’ll make the most.
I usually say invest, but since you’re moving soon, you’d probably be better off paying down the mortgage.
If you’re moving in a year or two, I’d avoid locking your money in investments. You don’t want to risk losing it when you need it.
