I don't know the zip code you are targeting, however I was born in nearby Gardens zip, but actually City of LA.

The problem for flipping is the non-standard SIC codes for this activity[sic:- standard industry codes per IRS]see  http://siccode.com/en/siccode/list/directory

Regular codes may affect the bid.

You can learn this from going to a notary directory like 123Notary.com and search out your zip code. many notaries list their prices on these directories.You can also go to The Society Of Field Inspectors (SOFI) website and list yourself there for anything that is listed that you qualify. 

One click and you pull all your buyers who buy within that zip code.

Pretty much every area now uses the IBC or international building code.

Plus I’ll give you a promo code for 15% off

So the city does an inspection to make sure there are no violations and everything is up to code.

This guy is a wealth of knowledge on building, remodeling and everything that goes with it from finding and managing subs, to purchasing materials, to construction code and navigating the permit office, but all you care to know is how much money he makes??  

I would say it is, I own property in some of the "bad" zip codes, but that pocket of the neighborhood is fantastic.
