As Marilyn says, you should talk with a Lender to see exactly what you can qualify for on the purchase of a home. I have included a link to a Mortgage Payment Calculator that may allow you to estimate the payment using a FHA, VA or Conventional Loan.
With the information you gave it sounds like you should not have a problem qualifying for a load to purchase a home. Of course the first thing you need to do is call a lender. I will be glad to suggest a couple lenders and of course you can check with whoever you do your banking with.
I also would be glad to help you find available houses in the areas you are looking.
Give me a call.
