I put them all under the same lease and it is drafted in a way that they are all together and severally liable for the property which puts them in a position to police themselves since if one of them mass things up they are all liable for the problem.

The examples in this thread boil down to over-zealous attempts to automate mortgage lending by allocating resources for mass marketing and flowcharts instead of people.

I will say when I spoke with the contractors and companies that do modular, they did not want to talk much until I told them the mass we wanted to do. 

Notices on their doors.Look in their mailbox (don't advise that) for adult magazines.... and while you are at it, see if there is backed up mail in there too.Boarded up windows.Those are good houses to scout and spend time on finding the owner.Get a list together, and send them a nice metter, ideally with a picture of the house printed (so the owner actually thinks you are interested in HIS house and not just mass mailing a ton of people).Please do not sent a hand written letter (UNLESS) you do it right (yes there is a way to do it right).Remember... most important thing.Yell "monkey power" from the top of your lung every morning out of the window.Between 4:30 AM and 6:50 AMGood things will come your way when doing so.

Oh while there is mass uncertainty (fear) in the market I’d recommend grabbing properties as the come available. 

Now I do personally think that once you decide on a market, you are better off directing your focus in the area until you hit a critical mass.

However, these mass mailings that have the intent to provide you real estate leads require the display of your broker's logo and/or info. 

He puts up with zero shenanigans, and has a fairly automated system. 3 days prior to the first, he sends a mass text.

Setting a ceiling for property taxes can help too.I don't know of a platform that allows you to skiptrace using APNs en masse.

So I have used this with success as well.. now obviously  its not mass market its identify through property radar what I want then go after it hard.. this is how I used Property Radar and my lawyer to buy that one I Lake Oswego that fell under the radar I had zero competition . so for CA investors property radar identify your targest then go hard at them.. shot gun approach to me is just that .. hit with 99% misses and what happens is you get discouraged and you quit.. unless your going to say I am going to spend 100k shot gunning per year and have the back up staff to run this stuff down..
