If there is a shared meter situation, I try to increase the rent to cover the utility costs and then combine the utility with the rent.

I think I’ll have a combination of the two, working and some parent support.

This is more common in older TH than newer ones but sometimes developers go the cheap route and make and start combining roofs.

For an older house, I would probably use a total for 12-15% for combined Maint/Cap Ex. 

If there were some structure in place where the PM was able to take some percentage of the prophet combined with some measure of how the overall asset was being maintained, I would be more interested.Something like, the longer a tenant stays and the better the property is maintained the more the PM takes.My experience is more of a heads the PM wins, tails I lose. 

This is ideal to be combined with item 1 and/or 2.We have used each of these to some degree (we never purchased as low as 70& ARV). 

Again, for a similarly well taken care of property around 22-25% of monthly rents works pretty well for a combined repair, CapEx, and vacancy budget.

San Diego may only have 1.3 million people, but combined with TJ is equivalent to 5 million residents. 

Depending on the age of the buildings, there could be significant structural, mechanical and electrical problems that could easily chew through a combined 3K per unit budget.  

In Maryland your bill for public water and public sewer service is combined in your Water Bill The Water Meter tells the State how much water you recieve in gallons, it is assumed you then pass the same number of gallon into the Sewer and your bill is calculated accordingly in 1 Bill.
