Due to a divorce, I want to take over the mortgage my ex has in her name. It does have two second mortgages- one for 3,000 and one for 15000. The balance on the house is about 80000. I think it has a value of at least 100,000 and maybe closer to 125,000. Should I contact a real estate agent to get this done? Or just go through the bank that has approved my mortgage? Easiest way? Cheapest way? Thanks!
