Check out historic norms of interest rates and don't obsess over half percents.

@Robert Freeborn my search has historically stopped anything north of Marysville. 

Historically RE usually gets tricky with sudden mkt crisis  or Govt.

There can be historical districts, hillside preservation districts and general anti-growth policies that you might not be aware of, and it might be difficult to become aware of unless you have operated in that space for some time. 

But when looking at a bench mark for prices I prefer to look at the inflation adjusted historic norm.  

If you do simple comps to look at historical pricing in that area, and compare that to "desirable" well known areas.  

Historic norm is 99x rent, which is basically 1%. 

They cannot be in a historical area. and they have a 10 day mandatory inspection period.

Economic progress (faster, better, cheaper ways of doing things) has historically been the way to stay ahead of inflation.

This coupled with a market that has better than average historic and projected appreciation rate.
