Is my neighbors water running under my building a big issue?
We are buying a 30,000 sqft retail building and recently found out from the city that neighbor building’s water line actually runs through under our building. (The waterline actually broke 12 years ago, and current owner and neighbor split the repair cost)

This line was put in place by the developer at the time those buildings were constructed. (30 years ago) City consider it is a ‘joint-ownership’ line between The building and neighbor building. 

However, the City admin told me they had some money in their Capital Improvement Program to fix this issue, but they don’t have a exact plan yet.

If we purchase the building we are buying it with the understanding that a water line runs under the building that also services Neighbors and there is no definite timeline for water service to be available at the front of the property instead.

My question is how big is this issue? I’m not sure if this is a deal killer issue or not. Current owner seems to operate the building for 20+ years without any issue. Does anyone experience anything similar? What would this potential problem cost me?
