If the articles of organization filed with the secretary of state shows you and not them as managers, then it may be a problem for this lender because the non-managing member does not have authority to pledge LLC assets as collateral for a loan not approved by the managing members. You should definitely visit with an attorney in the state in which the property sits.
You have to look at what the operating agreement says about this. It will probably say that manager's salary can be changed by vote of X% of the members. This may be unanimous or majority or something in between. Read the operating agreement.
If you do use an LLC for "managing" the rentals, consider a few things:
1. You must title the property and the leases in the name of the LLC
2. The LLC will protect you from liability, but not the properties themselves. You might consider multiple LLCs to protect one asset from the other.
3. You must have separate accounting and bank accounts for each LLC for it all to hold up.
4. Consider a series LLC, depending on which state you live.
Deposits are usually non-refundable for an apartment, unless the agreement was otherwise. The issue is a matter of proof. If you have 3 witnesses that can testify otherwise, you can try and sue him in small claims.
If the court awarded you the properties, he was probably directed by the documents to deed you the properties. He is required to sign a deed, and if he doesn't the court can issue an order effectively doing the same. Bad news is you'll need an attorney to enforce this.
Unfortunately you are out of luck with the foreclosure. Title to the home and liability for the loans are two different things. You are free to add a comment to your credit report to show people what the facts were...
