No matter the number of units, there is one roof, one property tax bill, one sewer line, one gardener bill, etc. 3.

Same property listed water bill paid by landlord so how much does it cost to put individual meters for each property so cost can be moved to tenants? 

I have used George and Bill at www.1031esi.com multiple times.

Are they still collecting rent and taking money that way, or are they billing you? 

If you are thinking about a new purchase with a heloc vs a current 30 year fixed rate, this could be a good alternative.Basically, helocs are billed based on the average daily balance of the account.

I looked at numerous live-in flip opportunities.

We have had duplexes with shared water, sewer, and trash billing, as well as shared driveways.The long term tenants act more like owner occupants, planting flowers, etc. and in some cases neighbors think that they are the owners. 

Anyservice calls to eliminate fleas or ticks will be billed to thetenant.

That's easy compared to trying to fight and erroneous $13k water bill (a real issue we had) or an insurance policy tripling (that too).

You've got to remember the home has already been through numerous inspections prior to delivery, so the time it takes to finish is minimal.
