If the offering is “good” deal, investors will find out either through websites, word of mouth, past investments with sponsor etc.  

If they have too many problem tenants, then it's incumbent on the property manager to either; work with late payers (like having them pay weekly rent, on the day they get paid), replace the late payers when their leases come up, and/or help the landlord understand that they need to up their repairs/capex budgets so the properties are in better shape so tenants are happier, not complaining as much and paying on time. 

I don't even look at them when looking for deal .I will see what the market is doing when looking at MSL homes .The deals I  find are word of mouth that need lot of work and  willing to dump money into the house ,I buy the location not really the house .

I do avoid renting to applicants when they open their mouth and blurt out crap.

I have gotten mine directly from the horse' mouth in the last few weeks.

Another idea for Multi's is to go to the local courthouse and look up recent evictions (it's all public record) sometimes there are some landlords out there who go through an eviction and have a bad taste in their mouth and would like to get rid of the property; and that's where you come in to take it off their hands!

Why do you think playing in dirt would make you happier and better off? 

It is a crystal ball, you either have one or you don't.See if those trying teach seller financing will put their money where their mouth is....probably not.

Or, mouthed off to TSA employees.

I should have read the fine print in the terms and conditions that stated if you say anything derogatory or bad mouth the company and products they can sue you.
