Quest water lines (polybutylene)

[Mark K.]

I'm debating buying a triplex that was built in 1995. The cash flow and COC ROI are both ok. The building does have quest water lines that are all behind drywall except when they connect to fixtures and appliances.

It would be expensive to repipe this as a lot of drywall would have to be cut and then repaired.

I know it's a risk to wait for a leak to start and then to repair just that section.

I'm getting an ok buy price and the seller won't go any lower.  

Any thoughts on this?
