The seller has started the eviction process. 2 unit should be delivered vacant and 2 occupied.

As long as you occupy 1 of the 4 units, you can have yourself up and going out the gate with 3 rentals all while using your amazing VA loan benefits!

The loans on a house hack are going to be some of the most favorable ones you can get since it is considered an owner occupied plus you should be able to get a first time buyer bonus of some sort. 

How can i stop homeless/squatters occupying my property? 

Rent for rooms in the owner occupied unit does not  have this same benefit.   

Every adult should be screened and approved before occupying.

The one residential is moving out, so I could go with an owner-occupied FHA or conventional loan.  

It's tough to recommend without sitting down and talking to you to determine what your goals are.What I would suggest is just buying an occupied or vacant house that doesn't need reno or minor reno, then either have a realtor rent it out for you and you take over day to day management, or you can put PM in place. 

We only got to go inside the ranch house and the 3 bed 2 bath mobile home as the others were occupied.
