I agree with Dave and Jean - about 1/3 of your income is high enough to pay for a mortgage because above that you are asking for trouble you don't need or want.
Just curious, are lenders still offering loans without adequate income to carry them (35-40% of income is the norm
This would be a terrible purchase for you, and you should find a home that's not more than 1/3 of your income, at the most. Please see a lender in that area and get pre-approved for a loan, as soon as possible. If the homes in that area are more expensive than you can comfortably afford, then don't feel bad about renting for awhile. Nothing spoils the pleasure of homeowning faster than financial pressure or the possibility of foreclosure! Check out your options, and make some goals. Maybe a salary increase is in your future, or even a transfer to a less expensive area.
