Throw a dart We have tech companies, two pro football teams, a huge stadium mega dev going up, more talk about the south LA area (think around the Forum) and the purple line going in and more planned over the next 7-8 years, and we will host the Olympics in 2028.

Of course there are deals to be made- unless you're looking for a magical purple unicorn sort of deal.

I was wondering if the colors correspond to the type of neighborhood, ie yellow/black/red correspond to C-D neighborhood while blue/green/purple correspond to better ones?

If you're okay with average cash on cash returns but a good chance of appreciation, I would consider PG County - there is a lot of money going into the "Greater College Park" area, the FBI moving to Greenbelt, new purple line coming through, etc. 

I just tried out Purple at the local Mattress Firm.  

The purple master bedroom was finished on Monday after two coats of primer and two coats of paint. 

I currently live in a 3-BR apartment with two roommates in Andersonville for $495/month, and after a bit of zillowing it looks like there is at least some potential to find a three bedroom condo where I could rent out the other two rooms without much risk of increasing my out of pocket monthly expenses beyond $495.I work in Evanston and my social life is along the red/brown/purple lines, so neighborhoods I'm interested in are anywhere from Lakeview to Roger's Park.I want to plug into the Chicago RE community by actually meeting people, particularly finding an agent and connecting with people who've done this successfully before.

Yet there are counties that are more LL friendly than others (hint- it's the ones that are purple, not overwhelmingly blue).

Value will continue to climb with purple line.How much is a modest cash flow to you ?
