One of the areas where condos may work in the DFW area is near the Galleria, the limit between Addison near Belt Line. The huge redevelopment with Dallas Midtown and all the surroundings is already on its way. I say condos because there are very few SFH/Duplexes available there, and mostly when you look at SFH that would work in the eyes of an investor.
Remember the rubber band effect, the center of DFW will stretch as it grows, and when it bounces back, the new downtown will be that area, the hub between 35/Tollway/75 and the I635. Drive by and you will see what I am talking about.
There is another area near the Costco Business where you can buy some little condos for less than 70k and rent them out for $900-$1000 /mo. Rough area, slowly improving, but it will be a tough area for a while.
Other than that, generally speaking most HOA's in DFW are not as restrictive and micromanaging as those in Miami, but they still hold power.
