Would I contact the previous closing attorney and tell them I need a quit claim deed from the people I technically bought from?

Personally, I've been investing more than 50 years and never looked at the demographics for a neighborhood one time because I always felt that you need more personal knowledge about the neighborhood e.g. whether it is blue-collar working people, whether it infested with gangbangers, what the ability to increase rents is, etc. and the only way to get a good feeling and understanding is to personally visit the neighborhoods in the daytime, evenings and on weekends because weekends and nighttime is when the bad people come out like cockroaches.

We have teams that bring us the real deals.

Almost every partnership I have ever seen in my sphere went sideways at some point; most sooner than later and often turned into a dumpster fire.If you do partner with someone, then look for a person who brings to the table what you lack and vice versa.

Both construction and eventual casino I would imagine bring more people to the area. 

Just like some people prefer pick up trucks to cars or Chevy to Ford.

But the reality is most people rent these spaces, a lot of homeowners depend on this income. 

It wouldn't surprise me, though, since most people opt for the cheapest insurance they can possibly get and then are disappointed when the coverage sucks. 

We bring in a third investor/partner? 

You generally may see some newer investors there but great to get to know people. 3.
