Alicia,
The current plan is to use an FHA loan because I will be able to use it as my primary residence while I am still in college. With my co-op I do have the luxury of working full time now and I am saving approximately 1500 a month. I also recently got a credit card and use it for anything I have to buy now and then pay it off immediately so that I can start developing credit. I know if I can get a 3-4 bedroom house I should be able to charge 4-5 hundred a month per room which if I get the mortgage payment low enough then covering that, property tax, insurance, etc. should be doable with a little extra to put back towards any unexpected expense with the house. Once I graduate I would start doing it as a one big monthly payment for the whole house and not charge by room.
The biggest problem I can see with it is not being able to obtain the loan without a cosigner but my parents are a little hesitant on the whole renting business.
