Gift giving to an appraiser?

[Nick L.]

I just had a bank-ordered appraisal done as part of a refi. I was extremely happy with the results. The appraiser has valued some of my other properties in the past, and I've always been happy.

I'd like to give him a gift to show my appreciation, but don't want to break any professional ethics code of conduct, or make it seem as if I'm paying him off. 

USPAP doesn't have any useful guidelines and anyway I'm not technically the client, the bank is. I was thinking of maybe a $100 gift card for a local restaurant - enough to be more than a token thanks, but not enough to suggest I was swaying him.

Any thoughts or experiences?
