Maybe you can provide us actionable advice i.e. what to do, when to do and how to profit off this correction? 

I have a friend that owns a vending machine business and in a lot of cases the businesses don't get a cut of profits, but the businesses want the machine there so it will be there for customers, and the vending company supplies the machine, keeps it stocked, and maintained and keeps all the profits.

If the first forecloses, then the junior is a sold out lienholder and may pursue the borrower in court for the entire amount.

(In this case, exactly $10,000.00 profit.

No profit or loss on this transaction since nothing has changed with property in the few weeks since sale.Here is the concern:There is an IRS lien on the property junior to the foreclosed loan, so the IRS has a 120-day right of redemption. 

Does it actually work and increase profits without turning off potential guest? 

Profit on sale is all free money so very simple solution.Sad that so much money is sitting doing absolutely nothing, it should be invested to earn it's keep.

The only thing that's confusing me about this particular calculator is that it calculates "repairs" every month which bits into the profit.

Especially if you are financing as the holding costs may eat up all of the profits in the event the contractor doesn't do their job in a timely manner.

In the end, all your profits will go to the lawyer and you still may not have the end result you want.But your post indicates that you like the hands off approach that these units have brought you so far and that you really enjoy being passive in your investments (who doesn't???).
