It will NOT be an A/B class property. 

Often the unit looks terrible when you’re showing it and is a waste of time.Most owners expect a property manager to work 24 seven but are only willing to pay them six cents to ten cents on the dollar.

The lot is paid off and deeded to our LLC, but lender will not do conventional loan to LLC for the remaining financing so we'd need to take out a loan in our personal names. 

Otherwise you still have leases for each unit and collections for each unit.I don't think you will probably get a reasonable break on PM just by buying more units. 

If 1 tenant isn't paying rent, at least another tenant will.

Similarly, if you put several Class D tenants in a Class A 4-plex, what do you think will happen to the property?

I am wonder if there will be any lien on it as back would have already settled before acquiring the ownership.

Stay patient, something will come up that makes sense.

We will be rebuilding the house that burned down.
