It will be bottom up in the form of ballot measures that citizen groups (whether misinformed or not) will propose and it will vary widely by region.   

@Logan Pou This is a regional question....for example...my city and county keep a master meter on water...so, even if you sub-meter for multifamily you cannot escape the water/sewer as an owner...the implication is that unpaid water/sewer becomes a lien on the property...pretty serious if there is delinquency...so you want to monitor that closely.

Regional differences matter. 

I don't know that region well enough to know if there was a real factor that caused migration from one locality to the adjacent or if it is a blip and temporary anamoly.A couple other observations that strike me are the number of double digit changes.

Finally, I find it really convenient to find a regional or national bank with branch locations, as being able to go into the bank and talk to a representative is really convenient.

The ordinance said the cap would be based on the inflation rate included in the Consumer Price Index for the San Diego region for April 2020 to April 2021They want to allow tenants to ignore their lease terms increasing risk and potential lowering return while setting max rent increase to CPI.  

There is a opportunity in the central Piedmont region of NC.

This is very regional.

One of the first metrics I started looking at was the price to rent ratio.I pulled a few pieces of data, joined it together, and visualized it to get a handle of what the price to rent ratio for different regions looks like.

And in my view, having a Condo in a region with a new influx of businesses and residents meant I could expect price appreciation and rent growth.
