I don't know how this works in the US, which is why I'm asking, but you paid of part of your mortgage already, so if you could sell you home for what you paid, or more, the difference would be cash-in-hand. If you spend all that buying the new home (assuming same price or lower), your new mortgage would be lower, and potentially cheaper, even with the higher interest rate.
You could also convert a 3% mortgage to a 5% for example. Because the owners of the 3% mortage aren't that interested in it any more, you could get that at perhaps as low as 80% (a former coworker got as low as 65%) of the original value. So if you buy a home for e.g. $200.000, you paid of $50.000 and "buy back" the rest at 80% you're now left with $120.000 of debt. You then get a new mortgage for that amount, and even at higher rate, that might result in a monthly saving. When the remaining amount is low enough, you could refinance and get e.g. a 10 year fixed rate mortage for a really low rate.
I don't know if you can do that in the US, but that's pretty much standard in Denmark. Most people will do that maybe 3 - 5 times during the lifetime of a mortgage. For the most part is make absolutely no sense, the bank just do some paper work, have you sign and then you owe less, but at a higher interest.
