Ask a landlord-tenant lawyer and get answers ASAP
I am sorry to hear of this problem. The delay in finding a tenant and dealing with repairs is not acceptable. Practically, changing managers/brokers is key. Second, the unreasonable delay and resulting loss give rise to a claim for breach of contract and breach of good faith and fair dealing, along with fiduciary duty. I wonder if they rented it out, collected funds, and didnt report as well. You can pursue a claim in state court for damages based on the breach, and may elect to have a lawyer handle on commission fee basis so you need more pay fees and also often need not be physically/personally involved if out of state etc.
Kindly let me know if that is clear and acceptable.
Please rate the answer positively.
I would look for a new manager and do the change once have someone in place. I would not cut ties until you can make a smooth transition. In the meantime, let them try to remedy the problem.
Kindly rate the answer as excellent.
