Your criteria is way too broad. Flipping and buy & hold? That's maybe a third of the real estate market in the US. Which one? What asset class? What tenant class? Also, the best markets for flipping are usually not the same as for rental property, because there's a ceiling for current rental rates, and they may lag prices significantly enough that you can't buy anything that will provide cash flow in a market full of flippers.
By most standards, you are living in one of the fastest growing and hottest markets; Dallas Fort-Worth. I would suggest you leverage your local network and look for deals in the area.
We like DFW, but we are currently looking for cash flow, which we are getting great results in Houston. If I didn't need the high COC return, and I had time to devote to finding my own deals, we'd be buying DFW properties from $100,000-$150,000 ARV
