Polybutylene Pipes and Conventional Financing

[Mark Manship]

During an inspections of a potential SFR this morning, it was discovered (and afterwards confirmed by the seller) that the entirety of the plumbing is polybutylene; to make matters worse, there are two known leaks below the raised foundation (below the off-grade portions). I'm now wondering how we go about getting the home insured and consequently financed (via a conventional mortgage) given that this material type exists. Specifically, I'd be looking for Florida insurers (property exists in Pensacola, FL).
