Hello, I'm a mortgage professional.
I would really need to work up a pre approval to determine the amount you could qualify for.
There are a lot of factors that go into it.
You do not need great credit, a 580 score will get you into and FHA loan that only require 3.5% down payment, you can even roll in closing costs.
If you have any questions or would like help with this you are welcome to get in touch with me.
