Think like a quarterback surveying the secondary...you have to checkdown your options, identify the open receiver, and release the ball quickly. 

Wisconsin law requires you to identify information and not hide behind a company.  

Your pest guy should be identifying points of entry.

However there are limits on how you identify your properties that may effectively limit how many your purchase.  

I should be easily identifiable by my long hair and my Death Star T-Shirt(Forgot I had a meetup today when I got dressed).

Usually address of the property is the series name so you could identify easily, However you can name anything you want.

Or did you use a property manager or realtor to identify/screen tenants?

Also, what experienced (or lack of) you have.There is a world of difference between projects that are stabilized and will cash flow almost immediately vs. projects that are in distress and require a lot of work just to get them habitable before units can even be rented.Another way of getting to know agents is to identify the market and then go on to Loopnet / CBRE / Marcus & Millchap / etc.

So as I write this process again for the second time I am realizing that my struggle would be identifying good sources for market indicators and assessing the indicators to the point that they would influence my decision.

My recommendation would to be to create a targeted marketing plan to identify and acquire off-market properties and/or to establish relationships with local, reliable wholesalers.
