First of all, allow me to say how sorry I am that you are having to go through this. I can only imagine how frustrating this situation must be for you. This sounds like a pretty complex situation based on the way it was handled. I am not sure why the broker advised you to pay the security deposit for the condo before your application was reviewed and accepted. Typically, the only money that is required when submitting a rental application is the processing fee for that application. Your security deposit should not have been paid until after your application was approved and you had an opportunity to review and sign the lease. With that said, I would advise you to review the terms of the agreement as it pertains to the security deposit (when it can be kept and when it must be returned). You may want to consider seeking the advice of an attorney in this situation to get a better sense as to what options you have available to you. Good luck.
All the best,
