And if he starts making an unacceptable excuse..."

Sounds like something changed for her and she's looking for an excuse, maybe some buyers' remorse? 

@Jim Adrian Please excuse my ignorance.. what items fall into "normal wear and tear" exactly? 

And you don't process their application fees, until/if you actually deny the one before them, and start to process theirs.This is to avoid any possible fair housing issues.And I learned to make appointments and if they were more than 15 minutes late without calling me with an acceptable excuse - denied. 

Later your excuse to withdraw consent can be your insurance guy told you not to do that, or your attorney or developer or perhaps the city may say that it invites a public nuisance, you know, it's never your fault!

(＠￣Д￣＠；) It's not an excuse though.

One point of my criteria that I learned to include over time - if someone is late, without a phone call and a darn good excuse - denied. 

Otherwise, they'll have an excuse for any mold that may occur in there.As far as the other stuff - If they break the vanity drawer, that's damage.  

Get a good lawyer immediately.California hates landlords and loves poor tenants with personal problems.Yes,she can sue you and probably will win a settlement from you after driving you insane first.Doubt she can prove that air conditioning had anything to do with his condition but,California judges like to look for any excuse to favor tenants.Good luck to you.

You can make excuses for them, but I think that is a bad idea.
