Replacement costs 100 unit mobile home park

[Kyle Craig]

Does anyone have any experience replacing water and sewer pipes as well as electrical lines for an entire community?
I have read it can cost in excess of $500k,  but some say it may cost closer to $200-300k just trying to get a more accurate idea of replacement costs for a 100 unit mobile home park on 8 acres.

Thank you so much BP!!  I don't know what we would do with out you!  :)
