If on the outside it looks like there's a shipping container in the back yard with a couple window cutouts, that might not make the neighbors happy, and might reduce the value of the main house.  

I'm just looking for anyone who has been successful going back to the seller (especially if the seller is the bank) and getting remediation in the form of a reduced price.

They have no commission to earn and only have my best interests in mind. 

Have you reduced the price?

You will learn and earn while you do it.If you don't want to do that, than consider investing in training.

In fact, it will increase your taxes by lowering your interest deductions as you pay down principal and reduce interest charges.

Most states have a 6% income tax, so if someone is earning $100,000 per year, that's $500 per month.

For us as investors the $20K delta could be the difference in whether or not we accept a deal based on the ARV - or worse, shortchanging ourselves in the amount of money we could actually earn.

With no savings any little blip of reduced hours and loss of income and they are toast.

As @Mindy Jensen says, it is very possible that your bank will reduce or waive the fees if this is a rare event for you.
