PM has breached contract; legal options for Out of State Investor?

[Hitanshu Shah]

Own a 4-plex in the KCMO Area. The Property Management company has breached the contract in terms of allowable expenses without owner's approval. I am also having communication issues with this PM - no email responses for days. Other lapses include forgetting to include utility fees in a new lease which was previously discussed with the owner but the new lease got signed by an existing month to month tenant and was not shared with the owner before the tenant and the PM signed it! I am an out of state Investor. What are my options ? including legal options if I need to go that route to recoup my losses?
