A quitclaim is a type of deed. Sounds like your mom added you to the title, not that you were on the loan. I don't think the loan will report for you. And you wouldn't want it to if you are preparing to buy your own townhome. If the loan reports for you, they would factor that into your debt to income ratio and it would effect the amount of house you could afford. Plus, depending on the LTV on your mom's home, that could cause problems in your approval as well.
LTV?
LTV = Loan to Value. If you don't have a lot of equity in one home that you own, it might make a lender nervous about approving you for a second home.
