They are all on separate parcels, paid off and occupied by long term tenants.

From what I can see around here it is a landlord friendly state so when you turn your prop into a rental you should do well as long as the numbers are good.Acquisition is all about entry price.

Can they prove how long it takes to rent a vacant property?

Yes, they can be slow with the first payment, but as long as the HUD paperwork is complete (essentially a promissory note here), the money always comes.

Also, if the sponsor is new, I am fine with less skin in the game as long as it is significant to their net worth.

Does it look like a modern-ish apartment with breezeways and internal stairs, or is it built like a roadside motel with long walk ways along the front.  

Not one lease in the entire country says a tenant can’t take the appliances when they leave, even long term leases.

Almost all 4 baggers occur through one or more of the following1- Long term hold riding price appreciation.  

If you can purchase this home with private money or seller financing and get a $110k loan, then you could do a rate/term refi right after so do a 90 or 120 day note to secure the property and get it in your name, then refi into long term debt using the full appraised value. 

@Roman Balmakov If you are planning on holding the property long term and have enough reserves to cover even worst case scenarios it could still be worth it.
