Not only is it rewarding career, but the timing couldn't be better - requirements change in January '08.
The sticky point is, when you come across a legitimate offer out there that can change your life, you're so used to hearing all the "static" from these fantastical work at home jobs that you dont believe it. True it appears too good to be true that you can be your own boss and get $80,000-$100,000 a year. If you have any doubts, take 15 minutes to do your due diligence and ask a REAL WORKING APPRAISER what they made their first year.
The "catch" is that its real- so it takes some REAL work. You need to take some quick classes, pass a test and get some experience. Having gone through the process - its definitely worth the effort. The reward is significantly out of proportion to the costs.
I got lucky, and had a friend in the business that walked me through the process. If I didnt have that, I might not be an appraiser now.
I did search the internet at the time but didnt really find much about how to get into the industry. But now there is a place that does just that: Helps you get into the industry, tells you how to find a job, what classes to take, etc.
Its ResidentialAppraiser.biz so if you're thinking about it, you should visit them.
