I didn't just happen into yellow letters, it was a trial and error process that included a few websites (back in 2009-11 when squeeze pages actually did work).

We won't begin our first campaign until January however we plan to do montly mail, around 1000 pieces and we hope to use a variation on lumpy mail, yellow letters, business letters, and post cards. 

I used to manage a gym and during the first 30 days of membership (free trial) people came maybe once a week.

My wife isn't totally on board, so its a trial run for us. 

There could be some distressed property that a Realtor has listed where they can't get it sold and would work with you, but you'd need to know how to deal with them.You can just skip the basic stuff and head on out, follow some guru or wholesale mentor program, take the low road, bump into problems, have more difficulties, step in it, get pie in your face dealing with other professionals, maybe get a bad reputation and be avoided by others, end up messing over some homeowner, for a few years learning by trial and error, or, you could begin by studying where all the professional types begin and avoid all those issues.

I do think there may be something to this strategy or variations of it, but also agree that it is probably overly complicated and certainly not the panacea that some are marketing it to be.

@Michael AdamoZoningHere's a good intro PDF from LA City Planning on R1 variation zones: https://planning.lacity.org/or... -- if you scroll down to page 7, you'll see more info on “R1R” Rear-Mass Variation zones, which is what your R1R3 zoning falls under.

I hand write the envelopes and letter, and have not tried to reinvent the wheel when it comes to effective marketing.I can tell you from my personal experience that any time I have tried to change that, hand written envelope printed letter or any variation my response has gone down.Set a goal each week on how many you want to send out, then divide that by days and you will know how many you need to do daily.Also, your letter does not need to be a long one.

There is a lot of experimentation, research trial and error involved in developing successful PPC campaigns.

There’s nothing that can teach you better than experience and trial and error.
