Worth every penny!
Possibly the best service I've received from a company.
Greg himself came out. A cheery guy, he wasted no time but also paused to answer questions completely and courteously. He knew his stuff and worked efficiently, even though I kept peppering him with questions.
After finishing his measurements and basic calcs, he sat us down at the kitchen table to explain what he did, what he knew about the home so far, what he was going to do, and set up accurate expectations. He made sure we were comfortable with his goals of fairness and accuracy.
Due to time pressure we asked if he could expedite the report, to which he set a good expectation of "before Monday" (on Friday afternoon), and we said ok... he delivered ahead of time.
After the appraisal came in, I contacted him for some clarifications and his responses, both email and phone, were prompt and patient, taking as much time as needed for me to understand.
One thing that stood out (besides all the above, which although one expects, one rarely receives), is his attitude of no BS, no talking-down to the client. Too often, professionals tend to treat the homeowner as if he/she is, well, retarded. Greg spoke to us on an even level, explaining when necessary or asked but never assuming we were idiots who were just lucky enough to have a half-mil to purchase a nice home. For this alone he gets top marks, and the rest is gravy.
