Watch out there, ZZ. Even though your point is valid, instead of saying comp-check followed by appraisal, say appraisal followed by an update.You must be very popular.

The problem with the free so-called "comp check" is not that the individual appraiser is doing something wrong, per se. It's that LO's and MB"s perpetually shopping for the highest available opinion on every property creates nationwide undiscounted collateral risk.
You can send out 100 average-Joe compent appraisers, lend 90% of the total value, and have a pretty sound bet. Take those same properties, with appraisal contracts shopped to the person willing to come in wth the highest value, lend 90% of that, and I almost guarantee you'd be upside down. Glad to see FHA seems to have figured that out (he said with fingers crossed).
