Readers of this column know that I have little, if anything good to say about the NAR -- which is not only the Realtors' trade organization, but a powerful Washington lobby. Nevertheless, earlier this week, when the NAR released data on existing home sales, their statement about appraisers' role in killing purchase transactions was dead on the mark:

"The increase in sales is less than expected because poor appraisals are stalling transactions. Pending home sales indicated much stronger activity, but some contracts are falling through from faulty valuations that keep buyers from getting a loan. Lenders are using appraisers who may not be familiar with a neighborhood, or who compare traditional homes with distressed and discounted sales."

Currently embroiled in this very scenario, my firm, Cirios Real Estate, is witnessing first-hand just how bad the new appraisal rules are.

Assessing a property's value in't rocket science, despite appraisers' claim that their extensive training and years of experience make them the only people qualified to determine home prices. All it takes is access to the right information, an understanding of what drives desirability, and a little pride in one's work.

That last criterion is perhaps the most difficult to find. Appraisers earn a flat fee for their services, giving them little incentive to provide the best analysis possible. Knowing they can now earn repeat business by turning around jobs in 48 hours and charging less than their competitors, there's little reason to go the extra mile to ensure appraisals take into consideration only the best information to come up with the best possible results.

Sure -- there are good appraisers out there with integrity that offer up great analysis. But as lower priced, lower quality work becomes the norm (thanks to the new appraisal guidelines), the best appraisers will seek greener pastures - as well they should.

Lawrence Yun, the NAR Chief Economist, finally got it right when he said, "Sometimes policy can lead to unintended consequences."
