It seems that about half the time we use a adjustments on properties with similar conditional/quality ratings that we get kick-back from the AMCs. The claim will be that they simply aren't allowed. I can understand if they wanted further explanation/justification for the adjustment and it would be easy enough to further comment on certain features amongst the properties and the varying economic ages or levels of quality.
How common is it for these types of adjustments or is this an over-analysis that should be avoided?
I frequently adjust within the same Q or C value. I also have a detailed addendum where I explain/support all my adjustments. I rarely get any kickback, when I do, its because they missed the addendum. The problem is that there is not enough granularity in the ratings, especially if following the strict guidelines in the report definitions.
There have been multiple threads on the AF, feel free to search them.
Condition ratings: C6? Only for distressed usually. C5, same thing. C4 and C3 are common. C2 typically is only on newer or completely renovated homes. For me, that means down to the studs if its an older home before even thinking about C2. My area's median age is 61, and there is little new development, so very few C2s for me. C1 is never been lived in, so again, very rare for me. So 95% of my reports are C3 or C4. That's a HUGE range of conditions to not adjust within a rating.
Quality is same thing--Q6 is basically duct tape and spit, always gets kicked back, may not be code anyway. Q1 and Q2 simply are not in my area--well a handful, I've only been in one I would say maybe Q2. There are about 100-200 Q3 homes, again by strict definitions. So again, 90-95% of my assignments are Q4 or Q5. Pretty wide range of differences there too.
I hope the next iteration of forms actually give some room (without needing an addendum) for some quality and condition discussion. Maybe they can make room by getting rid of the wood stove and screens lines in the improvement section!
I continue to think that quality, condition, and location are the three subjective items that will keep AVMs and hybrids from putting too much of a dent in the market. They will displace some appraisers for sure, but not wipe out the industry. If you give me the adjustments for those three, I think an AVM could be a very reliable predictor of value. But they can't now, and I don't think they will in our lifetimes.
Just as an example, one area I serve has a section where a ONE block difference in location can affect value by about 20%. I know this, and I know why, but no AVM does.
Condition is similar, and I continue to hold (though I may be in the minority even on this forum) that a personal inspection of the subject by the signing appraiser is of great importance. There are simply small details that a trained eye will see (in regards to quality as well) in a full inspection that may not at all be evident from 10 maybe clear, maybe not pictures delivered by a trainee or 'inspector'.
Maybe functional and external obsolescence are another thing AVM's will never capture. I saw a 5BR, 1.0BA house listed the other day. Good luck!
