How do you think is the best to handle this situation?

Many people want someone they know and trust to handle the transaction for the largest asset they will ever purchase.

I don't need print & postage services as I can handle this portion myself. 

Look for an independent agent who handles Commercial Insurance (especially construction or contractors). 

Yes, you should open up a separate checking/savings account to handle your business income and expense. 

How it was handled is messy, poor docs, potential fraud from owner forging end buyer signature without consent, no paydown financial logs(amortiz table) on the REC since there was no escrow company involved so the payments were going in direct to seller account who was not paying property taxes and the tenant is getting burned on this deal.(2)The contract almost non existent or sketchy at best.

Most PMs handle collecting rent, evictions, advertising and placing tenants and maintenance and repairs. 

They do not customize their services based on the owner's wants, and how they expect you to handle the property as a PM.

If you are splitting the bill, then it needs to be in your name because you cannot expect separate tenants to cooperatively handle this.
