many mortgages are assumable, people just do not realize it.
loans backed by the Federal Housing Administration, U.S. Department of Agriculture and U.S. Department of Veterans Affairs — can qualify as assumable mortgages.
It’s actually very few - I just went through a few months ago, my son and I owned a house and were both on the mortgage - I wanted to take over the mortgage myself as he was buying a new house and all I could do was refi, I could not assume the mortgage. I wasn’t going to refi at 8.5% so we sold the house.
