I will be in the same boat after March...I like my job and would love to do real estate in between my shifts(I'm shift work).

(I often feel like I am just shifting money around, but getting houses out of the deal!!)

In Florida, and many other places, I actually see a shift to more of the employee model.

I'm currently in the auto industry and need to make a change in my schedule for my family (from overnight to day shift) while I work on my investing on the side.

Many investors have shifted their focus to popping tops and scraping lots to build duplexes. 

I think Kashmere Gardens is shifting towards more Hispanic - according to this - but yes, I realize now, it is majority African-American. 

I had a big shift after some serious personal events myself. 

@Ihe O.I would pay lots more in taxes to care for the weakest members of our society.

I'm sure a whole horde of people on BP could come up with a better list than me, but some that immediately come to mind are:1) Natural disaster2) Significant changes to insurance rates (see #1)3) Changes to state or city laws regarding fees, taxes and rates, code requirements, zoning, rent caps, tenant-favorable laws, etc (you have more exposure here being in primarily one city area as well)4) Changes to state or regional labor market, especially in regard to contractorsNow in terms of rental market shift exposure, I think a geographically-centralized portfolio can still achieve diversification within a large enough city or region through properties in different geographic neighborhoods, Class A/B/C areas, tenant demographics, and general rent amounts (high/medium/low in the market).Now whether those (unlikely) risk factors are worth giving up all the home field advantages you've built up is a lot harder to answer, but that's every investor's decision.

I am actually looking at where I can do the most good (for me and society) and after about 13 years as a landlord, I think I may now be better as a landlord, turning around properties, selecting tenants, etc than teaching business topics (which a new instructor could take on)..
