We recently purchased a mobile home park that has brand new smart meters installed. Currently, the tenants are using about $45 a month in water/sewer on average. Should we raise the rents up $45 (that would get the park up to current market value) and keep it simple, or start billing back water? I know Frank has the $40 rule for not putting the money into water meters, but they are already there. Is it worth the extra steps to bill back? Thank you for your helpful input!
