The Phoenix Light rail, which will go through Phoenix, Tempe and Mesa, start up is just around the corner. Before years end it will roll through 3 major cities, through areas with increasing populations and lots of development and redevelopment.
I think this will be a turning point for Phoenix. I don't really know what it will mean for the entire city but its bound to have affect for those in the vicinity and even people who won't use it or care about it; because of residual effects of how others, visitors and businesses view the valley as a whole. For me the view is improving and the city is maturing.
Real estate investors should have their eye on the opportunities that the light rail presents. With it, there will be additional appreciation and cause for redeveloping a lot of the land, including large and small lots within walking distance to the rail.
It's not too late. In fact, the slow down should spur investors to take advantage of the depressed prices. There is data out there showing the benefits a light rails system has to real estate owners.
In Dallas, Portland, San Diego and other cities where light rail projects have been completed there have been increased in values greater then properties not served by the rail. The possibilities are there, even for single family homes or small apartments.
