I'm talking with a data/web guy to put together a private app to visualize population and job growth data.

@Prashant SinghIn our experience, you can classify neighborhoods, blocks, properties and tenants.While you are on the right path with trying to equate neighborhood class with property class, it doesn't always work that way - and is an opportunity for a smart investor.Yes, you want to stay away from the Class B/C property, the best house on the block, in a Class D area.

I might have to beef up a joist, and the books and web sites I've looked at really gloss over this.

What convinced me to choose this area over other candidates was the local news they stream over the web.

Here are some of those provisions in the CA Civil Code 1695 - But, as always, DON'T TAKE LEGAL ADVICE FROM A FORUM POST ON THE WEB, including from me! 

Would you classify your property as a luxury place?

BP won't let me post a web address, but you can find them easily. 

For newly constructed, purchased or renovated properties and also retroactive generally over the last 10 years, building components are properly classified into individual units of property and accurate recovery periods for computing depreciation deductions.

It’s free or for $5/mo per unit you get expedited transactions and a web portal among some other benefits.

I use the Register of Deeds site on the County web page.
