I work in downtown Fort Worth and travel throughout Tarrant County most of the day, but I live in the Dallas suburbs right off of I-20. My commute is about 35 to 40 minutes without traffic, 45 to 55 minutes everyday with traffic. Depends on what type of commute she wants how far out yall want to look, but here are my suggestions on the Ft. Worth burbs:
If you have kids, consider Mansfield. Great school district, short commute to Fort Worth and closer to things to do in Arlington. However, know that EVERYONE is trying to buy in Mansfield right now. We lost out on so many bids when we were buying last fall. Come to find out later that it was people putting down cash offers sight unseen from Cali smh
I just can't suggest Ft. Worth per say as I am not a fan of the city itself, but other burbs to try that would not be too bad of a drive:
-Alliance Area/Roanoke (when they finish 35 it won't be a bad commute into Ft. Worth), nice and growing area
-Southlake (very nice area, but not very diverse), Grapevine/Colleyville (also has a pretty good school district), or Euless area if you guys want to be in a nice area near the airport
- Burleson if you want a little more money for your buck (and in some areas bigger yards) and a smaller town feel with still not a bad commute. City has really grown and they have a number of nice housing developments popping up.
