Buyer responsible to tap-in to city water/sewer service? REO

[Jason Lee]

In analyzing a potential REO property, I came across this in the MLS listing comment section. "Buyer responsibility to tap-in to City Water/Sewer service which is available" does anyone have experience with dealing with the same issue? I would like to include this expense in my flip calculator as accurately as possible so as to not underestimate this potential problem. Thank you
