I compliment people on everything...their truck, tractor, outbuilding, dog, cat, big TV...occasionally something I like about the house...but, I don't typically care about houses enough to think anything is cool. They all annoy me at this point.
Building some sort of connection with a Borrower or Seller helps ease their mind, especially when the appraisal comes in short. When I was blowing and going making no conversation because I was afraid of Borrowers twisting my words...I got WAY more lender complaints from Borrowers/Sellers. I treat them all like a friend now, until they given me a reason not to.
