(see below)Above tenants have destroyed our bathrooms due to constant nasty toilet water damages.. and constant noise violations have caused my family to suffer from sleep deprivation.

Hello BiggerPockets, I went to an open house for a property that was listed as a 2 family but with only 1 electric meter, 1 forced-air gas furnace w/central air and 1 hot water heater.

Total cost of materials was around 70k, labor was sweat equity plus about 30 K in other labor cost (sewer later pull, back-flow valve, tankless water heater,4  mini-split units, sub-panel etc).  

@Ryan Kelly mainly north austin close to Apple campus and new water park in round rock

For homes for water heaters 4 Plex for water heaters I think you get the picture.

They claim even after running multiple rinse cycle, the water is running brown.

My water/sewer usually runs about 225 for our lower unit of a duplex.

There could be involuntary liens such as code violations, water and other utilities that survive foreclosure  and are not necessarily recorded 

Still have to account for appliances and hot water heater 12 years,hvac 20 year, bath and kitchen remodel 20 years,etc.

Prop. 15 though seems quite necessary to me although maybe also not the best solution.The state has two related problems that need to be solved:1) California has developed unsustainably for decades (often through federal government largesse), overbuilding public infrastructure such as highways and sewer/water lines.
