HI David,
First of all thank you for your service and congrats on starting your journey in real estate. I am new to the real estate game but do have a little insight on the College Station/Bryan and Dallas markets. I currently live in College Station and our housing market is kind of weird. We are mostly student housing and within the last 4 years have seen a lot of high rises and large student complexes being built. Honestly the market is really saturated and there is a lot of development in south College Station for single family homes. Some investors though are finding some good deals, but its just been a little more difficult since all of the development. The local government is also in a weird state as full time residents are not happy with the development and are wanting more strict building regulations for student housing. There are a bunch of great real estate agencies in town so if you need some advice on who to go to, just send me a DM.
For Dallas I know that the suburbs around the inner part of each city are really starting to turn around. A lot of investors are starting to buy up old properties and flipping them for good returns. The population is starting to push away from the city centers as more people are moving to Dallas/Fort Worth. I don't know much more than that but I know a lot of people on the forums know a great amount of information on Dallas.
Good luck!
Josh O.
