@Zach Yusuf a market analysis is good for a broad overview of an area. But depending on the scope of it, I don't think you'll really be able to hone in on it. Especially with an area as diverse and large as DFW and North Texas.
I suppose I'm more experienced with a commercial market analysis than residential. I know for commercial, factors like traffic count on the streets as well as target businesses within the vicinity are going to weigh heavily in the decision.
Whereas residential, factors like: large campuses (universities; work campuses - Toyota, Hospitals, Texas Instruments, Alliance Center; and military bases), and outward growth of a city will weigh more heavily.
Being the area that it is and the numerous major hospitals, university campuses, and large employer facilities have lead to Dallas and Fort Worth having more renters than owners. Which is a higher ratio of renters to buyers than the national average.
So from my experience in terms of honing into specific areas, it depends more on what kind of tenants you'd want to attract more of. And then just the level of home and area you want to be in (how much money are you willing to spend per property). I have a client with a $500k+ property that cash flows and I have clients with $200-250k homes that cash flows. Then there's plenty of people buying $100-150k homes and fixing them up to rent.
Tl;Dr - I think there's going to be a lot more intricate factors needed to really hone in on a specific area to invest in. However, in DFW the metroplex in general is strong so there's not really many "bad" areas to avoid. The majority of DFW I've seen has been great for a lotnof investors.
