Plus home prices are of even more narrow use in determining what happens on a macro economic scale since they serve as limited lagging indicator and much better ones exist, like new housing starts, lumber prices, foreclosure rate..

Mark Pence’s company has been great for our clients: https://kchomeinspector.com

I would never advise a buyer client to do that as you can pull an appraiser who might just hit value. 

I'm sure you're good at your job, but in this case I think that just accepting the odd numbers would best serve the client.

What is the best way to serve them notice before beginning the foreclosure process?

I played around with some of the ways of looking at value in the Introduction to Real Estate Analysis article by J Scott, but whenever I think of an offer I get worried I am either insulting him or giving away all my hard work (3 years of time assembling lots and getting it through city approvals, and serving as an uncompensated GC for net zero energy certification and most of the site work).

Does anyone know someone trust worthy and client oriented?

Fortunately we prevailed but I’m telling all my clients now that verbal from regional building and even their own permitting process is worth nothing.

What I wrote above does not create an attorney/client relationship between us.

First some background - I have lived in Orange County/Los Angeles my whole life (school and all) and would love to get involved in real estate investing to serve as a secondary income source.
