You may have chosen to put this question into a thread more related to multifamilies for better exposure to people with the answers, rather that in the intro, but I'm sure someone will be able to help you:) 

You don't say where you are advertising but Zillow is usually a good place to start and they will syndicate to other sites so you'll have decent exposure.

It's when you have say $10M in assets they could target that you want to divide it into 40 LLCs to limit your exposure to $250k maximum instead of allowing them to get to everything.DBAs are really just a low level privacy shield that gives the air of more professionalism when running a business.

As in, have Property 1 pay for Property 2 mortgage until Property 2 cashflows better.I'm guessing there is going to be ways to do it, but with possible liability exposure trade-offs, but I don't know.Does my description and what I'm hoping to do make sense?  

I suspect your getting  a No money down owner finance becasue the owner knows exactly whats up.and is laying off it major cap ex on a couple of newer investorsI would make sure it you had to replace the roof and flat roofs are a bear I would think especially in snow country.. if you don't plan for it you could find yourself upside down.and thats a good though even though you dont have any personal exposure.. seems like it could be a major time suck.and for sure you dont want to refi out unless that thing is totally fixed then your putting your credit on the line and maybe PG's as well.sometimes no money down owner finance you will find that as i state are really not that great of deal your simply buying into major issues.

Two entirely different liability exposures.  

I am learning as much as I can and we have both agreed that it is time to get some exposure on the site to further our knowledge and understanding of the industry.

The second pillar is a good insurance policy as that cover the majority of your exposure.

If you plan to look locally and are having issues finding someone who is putting themselves out there as a real estate person, look for a firm who does a high volume of business tax returns - likely they also have very high exposure to real estate issues. 

Exposure reduces anxiety and nervousness.
