As Jim said, master-metered.
But master-metered electric can be a nightmare. Search this form for some of Frank’s posts on this matter. The key issue is that you are probably responsible for the maintenance of the lines. Frank had one park that experienced a hot summer, and the residents purchased multiple window A/C units for their homes, and all they all cranked them to the ‘on/high’ position one summer afternoon, and his electric lines literally caught on fire. That does not make a city inspector happy.
You’ve got to be really careful about the condition and capacity of master-metered electric lines and/or master-metered gas lines.
Search for Frank’s posts, buy the ‘30 Days of Due Diligence’ book on this site (and the other books, and attend the Bootcamp), and be very leery of parks with master-metered electric and gas.
