As an out of state landlord, what steps to take to regain control of unresponsive property manager?

Have discussed filing complaint w/ DORA but lack of response from manager to requests for delinquent monthly statements & disbursements (currently 4 mnths), repair invoices and payments, and year end summary for taxes, have left us with no knowledge of what's going on or how to get important docs. Do i need to hire local Accountant, Lawyer to audit? Will DORA follow up for us? Hiring new manager not an easy option due to lack of professionals in the area at this time.
