Quetsion about a water leak in a peoperty that I might buy

[Wave Taylor]

I am looking at a 2 unit property in a nice area. Asking price $69,000. Offered $72,000. My real estate agent informed me that she received an addendum from the seller's agent, indicating that the water in the upstairs unit is off, possibly because off a leak, possibly from the bathtub. Should I consider pulling out of the deal? I am new to this. All responses we be welcomed.
