@Jessica Geisler, yes what you're talking about is becoming a Lead Generation provider. 

I've thought about just searching the deceased name on the county assessors website hoping to pull an address and then sending a letter to the executor.

It has high valued comps and there seems to be a great potential for a good ROI.The goal for me (and many others I assume) is to lower my monthly expenses while generating as much passive cash flow as possible.

The information is publicly available on county tax auditor websites. 

A great place to educate yourself is the SFMTA website where all the projects they are currently working on are listed.https://www.sfmta.com/projectsThe other way you could speculate is by following sheer density, such as Mission Bay or Potrero Hill where there are a lot of new developments going up - almost endlessly.

The instruction sheet will tell you which models can be interconnected, and you can often get that sheet as a PDF from the manufacturer's web site before you buy.I've also seen a suggestion to make sure that wired smoke alarms are powered from a circuit that also has a light on it that is used relatively often - like the light over the stairs, or the front porch light, or similar. 

I read some of their complaints on their Facebook page and the Better Business Bureau website and some of them were pretty bad. 

@Carley Corbin Usually each county has foreclosure auctions published online through the county website.

I have been searching for a system to automate generating leads for wholesaling. 

Try looking at the Metro Housing Boston (formerly MBHP) website.
