Not much to add to what's been said .. don't know WF Bank appraising, but the World Savings Bank appraisal brass took over the WF Bank appraisal department post-merger ... so if its run like WSB was when Rick Langdon was in charge (I think he is still the top appraiser at WF), it probably wouldn't be bad .. *BUT* ..
What if you want to take 2 months off to go visit/spend with family and friends on the other side of the country, or overseas for example? You are talking about switching to a "Less pay for more work, no vacation" kind of job. Fine for a 20-something newbie appraiser looking for experience ... but ..... do you REALLY want that kind of job at this point of your life? Or is it the lack of support staff that's wearing you down?
That's why I would NEVER go back to that life. I value my freedom and the ability to decide how much I am going to make this year.
