When we applied for a mortgage to buy our first house there was a glitch on my husband's credit rating. We took care of it, and he went to the bank to have them rerun his credit to get a lower interest rate.
Shortly after moving into the house I called the mortgage company to set up an automatic bill pay. They said my name was not on the mortgage and refused to talk to me. What??? I was a SAHM at the time, but the bank ran my credit. We are guessing that when he asked to have his credit rerun, they did not include mine.
We did a refi, and we are now BOTH on the mortgage!
You don't have to have an income in order to be included in the bills and credit cards. If you run into any trouble with adding your name to the current cards to establish a credit history (make sure that this would in fact happen!), simply open a joint credit card account at your local bank. It will establish your credit history as well as his (good or bad).
