@Rick StantonPer a lawyer I spoke with, all contracts are subject to interpretation, and can be broken.The insurance company has the goal of least out of pocket. 

The walls turning dark grey from filth is not normal wear and tear but would CA law interpret it as such?

If he gets hostile or difficult during the separation process remind him that you chose to interpret his use of the credit card as a lapse in judgement but are willing to pursue him for damages/charges.Should be a good small claims court thing if he didn’t pay you back.

I would never recommend others do that because it requires a higher level of sophistication and the right partners  This is really more of a general question, but if you are using a unique purchase agreement does that require a realtor on the other side to hire a lawyer to interpret and comment on it?

It is based on my interpretation of what is written but I do question how else it is to be interpreted? 

If you don't have an agreement with the PM, then it is all up for interpretation.

Mis-interpreted the posters initial question.

I interpret this to mean a decline in the market.

It really depends on the interpretation of each city.
