Financing two quads on shared large lot ???

[Lili Thompson]

Hi all!

I've found a great, cash-flowing deal for two four-plexes that share a common lot. My main question is this:

Is there a way to finance the purchase of the two properties separately? 

The seller will only sell them together. They share a center walk-way to the front doors of the units. 

Ideally, I'd use an FHA to house-hack the only vacant unit in quad A, and put down 20% on quad B, which is fully occupied.

Any and all info and suggestions welcome!
Thanks!

Lili
