Previously, I was working on RMBS litigation as a contract attorney. 

It sounds as though the individual is looking for someone known as a "commercial litigator", someone who handles business disputes; possibly between a contractor and owner, contractor and lessee, or contractor and subcontractor.

I've been reading up on Civil Code section 1950.5 and it sounds like I can't get charged for items she didn't say were an issue and that if the place was left in better condition than it was when I moved in, the cleaning charges shouldn't have been incurred.

I am a Civil Engineer and have worked with Engineering Ministries International (eMi) in Costa Rica as an intern after finishing my undergraduate degree.  

As of now, I am maintaining an regular LLC to hold my positions in my SFH investments.If I were ever to maintain such a complex structure, my main idea behind it would be to deter any litigation seeing the multi-state structure itself, which at least to my knowledge is the first defense, or probably second, after my insurance. 

Also why would you want that liability as god forbid there was a fire and sprinkler didn't work you would most likely have criminal and civil charges against you (note I am not a lawyer)

OP you may try the angle that the property manager advised with the threat of a complaint being filed with the real estate commission.. and see what that gets you.these issues are never worth litigating.. you will spend that much or more in attorney fee's and get nothing.. thats usually a lesson folks have to learn once in their career.. only one who wins in that scenario is the attorney... thats a fact.  

There so much litigation related to security deposits that it simply removes that liability of not paying back enough, the correct amount of interest, etc.

Again, this can vary from state to state and even locality to locality, but the proper procedures for this aspect of the process tend to be spelled out fairly cut and dry in most local civil codes.Feel free to reach out with any questions.

In case of the seller be the one who does not want to sell his property any more, he will pay twice the value of the given payment to the buyer, in accordance with the item 417 and 420 of the civil Brazilian code; 2) After this stage, normally in 30 days counted from the signing of the contract, the buyer, seller, and the whole papers for both parts in the negotiation, is presented to a municipal court, which a Public Writing of selling and buying real estate will be published (taking as base the previous signed contract).
