Property Management advice.

[Ben Chapman]

So I bought a turnkey sfh in Ohio. I closed on it at the beginning of June. Part of the turn key process was to have a tenant already in place (which there is) and a property manager (which there also is). My dilemma is that I have yet to sign any type of agreement or contract with the property manager outlining their fees and how I'll receive the rent. This was my 3rd turnkey  sfh purchase and previously those details were worked out just after closing. 

I contacted the property manager about this and their reason was that they were switching and upgrading their tenant owner websites and software. 

They sent me a check for my first months rent once the house was mine. They charged me 10% of the rent, but like I said, I've never signed any type of agreement with them. My other two property managers charge me 7% and 8%. 

All 3 of my sfhs are in different cities. 

Any advice on how to handle this situation? Should the property manager have sent me the full rent? Should I ask for the full amount until I sign an agreement?

Thanks in advance!
