Water in San Diego is real expensive.  

For example: Landlord will pay for electric, water and sewer charges up to $100 per month.

Side note; if you google 46218 the only photo that shows up is a gross water damaged basement. 

doors need to be power washed, gutter needs to discharge further from foundation (deck is uneven and breaking, possibly due to water erosion?)

Wood Floors not sealed, tile not properly installed and grouted, cheap flat paint that the tenants can't wipe finger prints or food splashes off, countertops not caulked so water gets behind causing water damages, the cabinets were painted over not replaced the list goes on and on.

What is the best overall water metering company you have found when it comes to ease of installation, reliability, and the cost of the equipment and monitoring?

I grabbed my multi meter and showed them the voltage in the water . 

Shared laundry meant a fifth utility meter and high water costs that I paid.

Subtract $350 for HOA dues, maybe another $400-$500 for electric and internet, and potentially water bills.
