Wow - Lots of replies! Thanks all, you've given me a ton of information to think about. Thanks also to those that have offered to help. Once it seems like he will get an offer to go, I will certainly PM those that have offered.
ksaleh - Once we get closer to a decision I will absolutely PM you. Thanks for the offer and the great information. Amusingly Richardson is where DH lived when he was in Dallas for a few years in the 80s.
GizmoTX - thanks for the link to the article, that is helpful information. I think we'll probably take the advice of everyone and look at the Fort Worth suburbs, seems to make the most sense.
Spork - glad to hear $250k buys a lot of house.
frog girl - thank you so much for the offer and for the heads up on the high schools, I'll add those to my list. I will definitely pm you when we get closer to making a decision.
GreatNateVIII and aschmidt2930 - thanks for the suggestions, I love the idea of being near public transportation!
chasesfish -we'll be looking at the cost of renting versus buying, agree on property taxes. We currently live in an area with cheap housing, but expensive rents. The bonus is that when the company moves us they will pay realtor fees and closing costs on selling a house as well as closing costs and loan fees when buying a new house.
Philociraptor - I'll add Grand Prairie to the list, thanks for the recommendation. I can't even wrap my head around houses for under $100k, it just amazes me. I think I've lived in high COL places (other than my current location) for too long.
