Your income will determine how much house you qualify for but it doesn't mean that you won't get approved. I have lenders that will approve you with a 580 credit score and they will tell you what type of payment they will underwrite and ultimately the value of the house you can purchase.
If you need help going through this process I can help. Give me a call and we will get you preapproved. Then we can find some homes that match your price range. I specialize in working the Lewisville market and there are thousands of a buch of 3/2 properties out there that are hoving around that 100k range that you can afford.
