Last year I listed myself on 3 different appraiser advertising sites. Each time I had a call from someone I asked them who referred them to me so I could thank them. 7 times out of 10, the answer was "Apppraiser USA."
In addition to some comp check calls, I have also received calls from individuals that want independent appraisals on their homes. One person was going through a divorce and wanted to know the value of his rental property before he and wife decided to split. Another was a high value property in a very affluent area in which the persons mother (the caller was executor of the estate) was going into a nursing home and they were trying to figure out what the list/sale price could be if they decided to sell the home. They didn't want a predatory Realtor pressuring them to sell, since they were quite wealthy and weren't really sure when they were going to sell.
For the year I've had my listings on Appraiser USA, in total, I've received at least 5 or 6 appraisals. I think I am #6-15 on a few of the major counties. Appraiser USA has by far exceeded my expectations, and paid for itself with the first appraisal. It has been nice to do non lending work, and appreciate getting that kind of business as a result of my listings on the site. In fact, I was getting worried the other day about renewal, and am hoping they send me an automatic renewal notice since I want to make sure my listings don't lapse. I've also changed my email address, so I need to be sure they have that information in order to receive emails about my subscription. I highly recomend Appraiser USA
