@Stephen Green I see a lot of people pushing North DFW but personally (my investments) and properties that I've helped my clients acquire and mange over the last 8 years, we've had tremendous success in Grand Prairie, Mansfield, and Arlington (South side).

@Damon Ng thanks I'd love to start doing some get togethers with like minded people in in the area. do you have anything going yet?
