I've been able to automate things with the city i.e. taxes, utility bills, permits along with "case management" for assigning contractors for quick solutions. 

Currently 21 are occupied.Lot rents are currently $190 and Park owned homes are between $350-400 currently.The place went on market in July 2019, however he didn't have the water individually metered.This created a water bill between 1500-2000 a month, and killed the NOI.The seller just had the occupied lots individually metered.

Should they pay the bill so I don’t lose money

Do they continue to receive the bill?

My largest electric bill has been $12.00 Roof inspector did not do a great job this time.

I will be closing on my first four plex rental and I am running into the issue that the water and sewer bill is sky rocket high. looks like the tenants use up a lot of water.

Hopefully that same firm can assist you in minimizing your tax bill while filing a compliant return.

People left because the property management wasn't paying water bill or doing maintenances.

NOI is the number that you want to care about MOST ... with MFH it’s important to understand all of the costs .. like water bills , electric bills , maintenance, tax bills, trash service etc .

If you loose your one tenant you pay the bills and your return on investment suffers a great deal.
