Per our contract it is written out as:Security Deposits(1) During this agreement, Broker will maintain security deposits received from tenants in a trust account and will account to the tenants for the security deposits in accordance with the leases for the Property.(2) Except as stated in Paragraph 4(I), after this agreement ends, Broker will deliver to Owner or the Owners designee the security deposit held by the Broker under and effective lease of the Property, less deductions authorized by this agreement, and will send written notice to the tenant that states of the following:(a) that this agreement has ended;(b) the exact dollar amount of the security deposit;(c) the contact information for the Owner or the Owners designee; and (d) that Owner is responsible for accounting for and returning the tenants security deposit. (3) If Broker complies with this Paragraph 4C, Owner will indemnify Broker from any claim or loss from a tenant for the return of a security deposit.

So I authorized the tenant to call in an appliance repair co, they collected a $100 one time charge, and said the mother board controller needs replacing and it would be like $500 and there would be a one week wait. 

This might be a case where the board doesn't know what the property manager is doing, and the board has the ultimate authority on this.If you've got an email address for a board member, pop them over a polite email and explain the situation and that may be all it takes as well.  

Yeah...lots of people try to negotiate with the bank but the bank isn't the owner of the property and has no authority to work with you.

No title company, "buyer friendly" attorney or broker has the authority to do so .  

Personally i like renting to section 8 tenants because part or all of the contract rent is paid by the local housing authority.

They are a self-regulated org with no authority so some business don't even bother with them.  

(Assuming I understood your post correctly)The less autonomy and decision making authority I have over a prospective deal, the less comfortable I am with it.I'm not saying it's impossible that the deal might be legit and that their business model just happens to be that they make money from as many sides of the transaction as possible...but for me, I'd have to have more information on them and understand (and believe) the real why behind their business model.

Report to Authorities for them to take action2.
