About Keylock


Head Shot Crops Web-3Sarah Miles has been an independent fee appraiser with Gem Valley Appraisal since 2002, after graduating with honors from Idaho State University with a Bachelor’s degree in Business Finance and minor in Economics.  She now owns the company. Unofficially, she has been part of the appraisal industry from the day she was old enough to hold the end of a tape measurer for her mother, Ruby. In 2015, Sarah received her MAI designation from Appraisal Institute.

Sarah’s fascination with economic modeling applications in real estate formed her conviction that good data matters. Experienced in appraising agricultural, commercial, residential, and special-use properties, Sarah’s area of expertise is in the application of regression modeling in the valuation of real estate, instructing, and presenting multiple regression analysis to several industry groups.

Outside of the office, Sarah is a dedicated mother to her young son Tommy, tries her best to keep up with her ever-adventurer husband Kyle, and enjoys the companionship of her two grown step-daughters.  Sarah’s LinkedIn profile.
