I understand that I am giving up value but I also understand that my holding costs are pulling me down financially and am pricing to sell.I am happy to take phone calls, schedule a showing or multiple showings.

Hard money is probably the most common way flippers leverage to buy a deal, although that requires down payment from you and/or another private investor (usually 10-20% down). 

In particular: "Realtor Only" or "Agent to Agent" Remarks - typically a freeform text field where agents can share details and amplifying information that they do not want to share directly with the public, and Attachments - It's pretty common for most due diligence information (seller's disclosures, surveys, rent rolls, operating statements, proformas, etc) to be included as MLS attachments.

Its pretty common, as many sellers do this so they don't disturb the tenants..  

From there, taxes are paid with your mortgage and kept in escrow until due.Is it common to waive the escrow amount if you're putting down 20-25%?

50/50 is common and keeps people happy from my experience

For instance, if the current owner is paying the water bill and the MFH property is submetered, maybe it makes sense to put the water bill back on the tenants (except for the common areas).

The problem I ran into with the first bank (and confirmed by the second one who returned my phone call) was “to consider any income from 1099 self employment I would need a tax return for the past two years, and they would average the amount.

Not sure how common this is or whatever as this is my first actual deal, but it is possible it appears.

Won’t allow me to post his phone number.
