That’s an interesting question. You didn’t mention the interest rate on your mortgage! But while you are working, you might be better off refinancing it to the lowest rates — and then holding on to it. I didn’t say take out a new 30 year mortgage, but maybe a 10 year mortgage would leave you with an affordable payment — and still have cash for emergencies. And after you’re retired you can decide whether you really still want the responsibility of a house — heating, repairs, snow shoveling, etc! At that point, you could sell and use the cash either to rent, or to buy a smaller, simpler place to live.
