Sorry for the long winded back story, but end game is to put a A frame on the existing 20x40' stem wall above near where I"m standing, and put some stairs into a drop down area below for chairs/fire-pit overlooking the river canyon below (but out of view) under where the drone is flying.

So yes, you can have solid concrete walls, it's still going to burn down.I have read that worst case up to 80 million Americans will relocate in the next three decades.

Is there a clause stating he can't remove the copper pipes from the wall? 

Quote from @Account Closed: I would say.. can you save the tub and re-glaze and redo the tile on the wall can save you $1,000 or more just on materials and labor..

Moving walls usually requires figuring out what is or isn't load bearing and likely putting a large and usually expensive header.

Selling sounds great on the surface, but then I would be entering that market looking for a "Deal". 

So if there is a fire due to natural cause, HOA insurance will cover the cost of exterior repair like painting the exterior walls.

For example for a few holes in the walls they have someone paint an entire unit and take their spread.

If E has any priority over B, for instance, I would not invest in this structure, given that my bank account puts me at a Class B share (side note, their Class B is a little more GP friendly on the surface, than other groups, but devil is in the detail).  

I can see in that one pic that you could use a bit more artwork on the walls.
