It helps to think you're taking steps towards it rather than in a hold pattern, at least for me.   

Use that as your base fact pattern. 

Every property of interest is further evaluated based on subjective data (experience, judgment, aerial views, traffic patterns, the barking dog next door, etc.).

One of the most interesting things about Bay Area RE posts is reading thoughts and views from folks who don’t live in the area or invest here or even visited but have a “clear and cynical” view on the local RE, politics, weather, migration patterns etc.

Migration patterns.

Hello,I do come across tenants that bargain on rent during tenant screening, and I noticed a pattern lately that tenants who bargain a lot tend to end up as trouble makers.Are there any best practices on when to filter out and pass prospective tenants who bargain?

Try to recognize potential development patterns in the path of progress.

Is it global migration patterns?

Relying on the numbers :) (notice a pattern here?)

You'll start to see patterns of what works.
