Funding an unisurable home

[Peregrine Smith]

I am looking at a live in investment property that has hail damage on the roof. It is liveable however I don't believe that my lender appraisal will grant the roof insurable, in turn voiding my contract with the buyer due to lack of funding. My intention is to get an "investors loan" of some sort for the period it takes to fix only the items that deem it as uninsurable, at that point I would like to reinvest with a VA loan. The issue is that I don't know any opportune funding types or strategies for a situation like this. Does anyone have any insight or experience on ways to get this funded?
