I feel I have gained all the knowledge from the famous @Brandon Turner but I need a splash of confidence from the community to get me over the hump. 

So, for instance, someone at the bank establishes the upset price, and say through hook or crook you find out who this guy is.

Your strategy may depend based on area but in my instance I don't have to worry about finding someone quickly if needed. 

For instance, in the morning when I wake up I would check the RE websites such as realtor.com or zillow.com.

Or the type of transaction--for instance, financed or cash. 

Especially for the end buyer who’s strategy is using the property as a rental.For instance, if you have a property that CF +$500 per month, maybe it doesn’t matter whether you buy it for $80k vs say $95k.  

For instance,When the market crashed, the banks had too much debt and the FDIC mandated selling the notes and/or foreclosing on the homes before they would have more cash available to lend.

Being a big Audible fan the Famous Four segment is drumming up quite a bit a business up for Audible.com as I keep buying books and running out of credits lol.

For instance, I've seen people use gross income instead of net operating income in the numerator.

Other than it being smaller, painting a house between tenants is going to cost the same, a new roof will cost the same, a new air conditioner, hot water heater, furnace will be the same cost etc.For instance, it costs us about $1,000-$1,500 plus a months rent as a leasing fee. each time we change tenants, by the time we paint, do landscaping, repair damage, change locks, patch holes, paint walls that need to be painted get a make ready clean.
