This is the problem, they will create more BS for the appraisers to jump through, while at the same time keeping the CMAs and BPOs out there for the large number of Realtors. They need to stop playing around and make Ohio a mandatory state, PERIOD. CMAs and BPOs should be used only for listing purposes, PERIOD.
It will never happen, the Realtor lobby is too powerful in Ohio. Leaving out the sheriff sales and probate is another instance of the "buddy" system in Ohio. You only need to be a landowner in the county you are "appraising" in and there are too many sheriff's out there with their buddies in tow.
