Purchased a home in the hotspot of North Dallas area and have tenant waiting on closing and a few minor updates and repairs.  

This area however is a hotspot that is appreciating rapidly. 

As of now I am looking to make my first purchase in the next couple of months, but before that I would like to get a lay of the land, and a firm grasp of what investors are looking and the hotspots to go to as well as the neighborhoods to stay away from.

Eagle Mountain (city centers) I think is going to be a nice hot spot in the next few years.

Does anyone know of any hot spots in the area?

And let's assume I've found the house I would like to flip, no real estate agent needed, in a good neighborhood that's in a new hot spot of the main line.I guess my question could be a bit more pointed.

3 day workshop for a "mere" $2,000, which I've heard is just another sales pitch for a bus tour of Armando's magical hot spots @ 30k-50k admission.

The first is a hot spot for turnkey providers and second is not (the second is where I prefer to buy.) 

Unless you think people are just as happy to drive 45 minutes to get to the tourist hot spots, there is most definitely a limit on developable land.If you can get the same returns on the NC side, go for it!  

Universities employ lots of people and are hot spots for property investing.
