Edambro, regardless of how much you have to put down, or the fact that you have been renting for 7 years and have never been late, you still have to qualify for the mortgage. You income, assets and credit will have to be evaluated by a mortgage professional. Part of your credit report is what monthly debt you have. That must be added to the mortgage payment, which includes principal, interest, taxes, insurance, mortgage insurance and any homeowners association dues, to arrive at your debt ratio. So, if like a previous poster who asked about qualifying, you are paying $1200 a month to lease a car, and are a waiter who doesn't show all their income, you may not qualify regardless of your excellent rent history.
