I bought my house when FH and I just started dating so only my name is on the mortgage. FH and I were talking about all the "legal" things we need to take care of after we get married and were wondering about mortgage. Do we have to pay closing costs again if we want to add his name to the mortgage? Do I have to pay anything if we don't add him, but I change my last name on the mortgage? FH doesn't care if he is added or not because we plan to get a bigger house in a few years after we start a family, but I'd like to have him added if we won't have to pay a fortune to do so. Anyone have any experience with this?
