I would have paid another experienced local investor (an unbiased party not having anything to do with the sale of the home or selling me services) to do a thorough video tour of every inch of the house before submitting an offer. 

The rate would typically be the prevailing rate at that time.

Ironically when I first hired them their service was quite good. 

I understand the above services are not free and so willing to pay for it and also open to be fingerprinted.

If you're seeing more price points that are higher than the norm typically it means that either the market is shifting gradually up or that there's multiple people involved in that deal "chain" before it gets to you and everyone is adding their markup.My advice would be to attend a few local meetups to brush shoulders with other investors to pick their brain about whats working in your market AND to start marketing direct to sellers instead of trying to get the deals from wholesalers. 

They work long hours and typically just want to rest on their days off.

They also have couple of sister companies, DFY Service solutions and Mansa home solutions.

Make sure you have that in writing.It is typically a simple quit claim deed.

The CAM is typically the common expenses divided amongst all tenants by square footage.

Obtaining competent management was an issue, I have no confidence in the service personal in the local area.
