I've seen stickers with Feb or March on them, and there was clear signs that the plumbing had already been compromised by freezing.

Screen, screen, screen and don't ever compromise just to get the rent checks rolling in. 

Some of the above compromises make sense for both of you.

Is the tree compromised ?

My initial thought was this could be a compromise on the builder's part so that it may be classified as a multi-family dwelling.

So a medium might be a good compromise. 

His health is heavily compromised, the local agencies are not helping him much(who he uses for medical, food or moving needs) & he has much trouble getting around.

Corrosive to HVAC plumbing and electrical very hard on the Lungs especially for a compromise immunity system, to identify the Chinese drywall go up in the attic and look at the backside of the drywall in the ceiling you will see Chinese printing in red.

I also decided that my calculations for repairs and updates needed to be reduced, so I have been calling more people and stores to find the best deals and not compromise quality .  

If not and the compromise from either if you necessary to make it work is unrealistic, then you move in a different direction.
