Van Wolslagel


 Van has been a California guy all his life being raised in what he calls the “OC” next to the beach which allowed him to surf, work, attend college in @ Fullerton and @ Biola Univ. with a short break for the Vietnam war from 1968-1971. After I left the Army, a friend introduced me to real estate. My first Real Estate job included Sales, Appraising, Loan Application, Escrow management and HUD REO control officer all in one while making a whopping $800-$1000 mo. And even having money left over for my wife and I to move to the San Bernardino Inland valley. I left Sales, Loans and Escrow, but I never left appraising as I really new I fit well into the valuation side of real estate, learning new markets and areas, back then it was a regular thing for one day to be in San diego, the next in Los Angeles, and even a week end jaunt to the East Bay San Francisco area and turn times, 1-6 weeks depending on the work load and no one called to ask “where's my appraisal?"  Van is president of the Victor Valley chapter.

Van has owned and operated his appraisal and home inspection business over 40 years and am still looking forward to each day doing the same. Being involved in the REAA allows me to interact with persons in my same field of endeavor enabling myself and other members to exchange appraisal, ideas and challenges through a one to one or group interaction that I can't really get without the membership.
