I have done a small amount of research and it sounds like the replacing process can be a little tricky, quite sensitive. 

To qualify I too take income sensitive student loan payments, the lowest payment possible.

This is a bit time sensitive if that influences anything.  

I am sensitive to having multiple credit pulls even though my FICO is right around 800, but still I want to be able to compare rates from different sources/brokers.

Off hand I would say it would make a good place for a brick/stone company to sell their stuff provided there was an office where they could run their business.I would also say lumber yard but that would be a bit more sensitive to flooding.Stock yard and auction yard/auction facility could be good too.

Maybe how to sensitively convey to them the realtor is wrong and the house down the street that sold for $20,000 more had more sq ft.

They are connected to your account but never actually see or have access to your sensitive banking info.Hope this helps!

At the end of the day it is mainly a safeguard agains't the risk associated with an investment property

What can i do to safeguard my interests?

Mail your payment (please no cash via mail) to: Citizen’s State Bank..PO Box 110 Moundridge, KS 67107...Quite a bit of somewhat sensitive personal/business information Michael.
