If you are buying in Texas, when you are figuring your house payment (principal and interest) make sure you know what your property and school taxes will be because they are pretty high. Don't take anyone's word for it. Calculate it yourself so you aren't surprised with a huge back tax the 2nd year you are in your house. We had to pay back taxes plus the new rate and our house payment went up by $500 a month for a year and then $250 after that. What a bad surprise.
Good luck and I hope things work out the way you would like them to!
