First Republic Bank has similar programs based on the census tract.  

Currently many large equipment tract loaders, bobcats, Excavtors, etc are offering 0% financing for 5-6 years.

It's possible to buy a house on large tracts of land that can be depreciable on the outskirts of the city but the cash flow probably won't be there without a little creativity. 

Before you do anything you need to:1) talk to the city zoning department and see what uses are allowed on the property.2) check out the survey to see if there are any portions that are not usable due to setbacks, easements, etc. in addition to what the maximum buildable area is based on the zoning restrictions.3) see what utilities you have available at the tract (water, sewer, gas, electric).4) based on the above, see what the options are and if you think any of those would be profitable.5) decide if you want to build and operate whatever that business is or just sell the land to someone else to build. 

@Andrew R.I use REI Hub to manage my 4 LLCs rental properties to keep tract of 12 checking, savings and trust accounts.

My answer is this: in a tract of all similar houses you will probably be able to DIY with error of 10% In custom or luxury you could be off 40%

Narrowed it down and put in an offer, and after a bit of negotiation, went under contract on a 2-story tract home (4br/2.5ba/2575sqft) in Rancho Vistoso, an upscale community in Oro Valley.

but if you think it's a good trend that tech companies are saying "we are leaving California" along with many high profile rich people, you're crazy.How about this, because I'm curious:  Why do you think the various sites that tract this stuff (let's use the U-Haul one way data) show CA cities being so highly represented in the top 10 places people are leaving and various red areas as the top 10 areas they're going to?   

I'm guessing they have census tract data in the database that can automatically determine that.
