There are no other title search services specifically setup to work with investors and provide the type of report you need to bid at the county auctions without losing your shirt.  

And I would get these folks calling me all saying they were cousins of the shah or some shirt tail relative  which was code for they had a lot of cash.so I started showing one around in particular bought him lunch a few times and he always ordered the most expensive whatever ..

I want to leave a lock box on our shirt term rental in case there is a problem with the electronic lock.

I did walk away basically breaking even (probably out a few grand, but not losing my shirt) and with a much better respect and eye for a "great deal." 

How can an investor best exploit another set of investors who will likely lose their shirt on bad deals of the past?

A good way to classify A - B - C - D properties are by the shirts your tenants are wearing.A Properties = White collar professionals wanting nicer amenities to entertain friends.B Properties = Blue collar working class, bread and butter cash flow tenants that respect the property.C Properties = T-Shirts week-to-week paycheck residents, usually a mix of Section 8 and working classD Properties = NO SHIRTS gathered on the front steps drinking 40's out of a paper bag at high noon.

I need to buy a new shirt as I just spit out my coffee and have coffee stains all over it after reading this post.

Some folks do well and others lose their shirt and go bankrupt.It is definitely a risk and you are creating a job for yourself, but judging by your wording, you kinda want a business instead of investing.It is scalable based on your area and how much risk you can tolerate.

Whoever is buying these for 90 cents on the dollar and having to go through a BK before foreclosure is going to lose their shirt on these assets. 

Unless you really know what you are doing, you can lose your shirt.
