As for Alexandria specifically in terms of regulations don't take advice from a public forum - look up the laws yourself and make sure you understand them.

In order to comply with SEC regulations, there is no platform to publicly announce your deal to the crowd (both posting on Facebook and publicly announcing it at an event could be construed as a solicitation, which is not permitted under the structure that most sponsors in the group use).

Also, not sure what relationship you have established with your property manager but typically people hire managers to take care of this part and be tenant-facing.  

@Eric Andersen definitely put weight into what @Michael Baum wrote and do your own research on the city regulation/zoning.

Definitely follow the regulations in the area and if permissible I would offer to attempt to find an acceptable tenant and terminate their lease when that happens but in the meantime they will need to continue to pay.

When it's a well established company like Apple, they aren't likely to be going out of business so there is some certainty that there will be in increase in demand for quite some time.

Can regulations change?

This includes all charges paid, utility accounts set up, renter's insurance established, lease signed, etc.

In my opinion, you have to establish your own investment objectives. 

While I believe I operated with many of these strategies and tactics EVENTUALLY, I spent a long time “spinning my wheels” early on when trying to negotiate before establishing a rapport.
