We've seen some great deals in some of the Dallas suburb areas such as Denton, Plano, Denison and Temple & Killeen if you are willing to go a bit further out
Cash flow is often a matter of how much you put down vs your loan/leverage. Probably takes more down to cash flow right now, but thing seem to be improving both on rent side and price side of the purchases.
Texas will likely remain a strong market. I wouldn't say there is blood in the streets yet, but now may be your opportunity to buy when there is a lag in the market. Less competition.
From all the deals I hear that are not even announced yet, I would say Texas has about as good of growth prospects as any place in the nation.
I'd look at someplace like Sherman and Denton. Just north of the metroplex. Sherman has good industrial base, two hospitals, two colleges, not far from the metroplex. Seems like very few apartments....mostly older rental stock.
