I did some research online and it seems that new legislation allows and somewhat requires phone companies to actively block phone numbers that it suspects of being SPAM which could be any number that calls the same phone number 3 or more times.

I wanted to update you on this legislation.

Check out Truecaller and other Apps for eliminating SPAM.Not sure what this does but Congress just passed anti-SPAM legislation, and the cell phone carriers are also required to develop technology to identify robo callers.

He confirmed that SB9 is an option for my property, but also mentioned that it hasn't been too popular since it passed legislation last year.

One notable exception is "(4) If the ordinance supersedes any zoning restriction established by a local initiative, the ordinance shall only take effect if adopted by a two-thirds vote of the members of the legislative body." 

Every city in California is handling this new legislation differently and have their own procedures . 

In fact, new legislation passed just last September, 2017 clarified the rights of wholesalers to do exactly what I just described. 

Or, you might ask for something else like the ability to do lease options in TX.You need to be able to express why the current law is a problem, articulate a tailored solution that isn't likely to have unintended consequences, and explain the benefits of the proposed change to the legislator's constituency to your representative (more likely his intern.) 

Or is it that so money people have set out on the wholesaling path, didnt learn what the needed to learn, did terrible deals, and caused legislation to be passed to cause a barrier to entry for wholesaling?
