Creative options for fire damaged duplex?

[Mark W.]

I've got a bead on a duplex in an area I like that has significant fire damage.  Back unit is a full gut due to extensive fire damage (kitchen fire); front unit requires minor rehab.  There is significant damage in the attic which would require replacement of the roof and about a third of the rafters.

Seller is willing to sell as-is, however, I'm not sure I can make this work. ARV is ~130k, rough estimate of repairs is greater than that. I don't mind having some of my own cash in this, but we're probably looking at 140-160k worth of rehab.

I would hold this, not flip it.  Any way I can make this work?  Have seller sign over insurance settlement?  Seller is out of town and seems motivated to be done with it.
