I have access to the MLS.

I have not been directly involved in that space in a few years, but at that time crowdfunding for real estate was not permitted and regulations still remain fairly restrictive (accredited investors and the like).

If you have access to the same amenities then I don't see why it would matter how big your unit is. 

For instance, as you've described the building w/ commercial on 1st floor and residential above, the housing section of the building code considers the 2nd floor to be the "ground floor" which by code must be accessible, so you would need an elevator or ramp up to the 2nd floor. 

A easement grants access to something, in this case the roof, Unless your terms include verage that allows you to terminate the lease it's is use governed by the lease.

So this room has the furnace, water heater, and laundry in it, and they are only accessible through this room.
