The subject as a comp, after appreciation is applied, aligns with the 5 other comps adjusted values.
We believe in this case, it produces a better report since it is physically, and locationally the same, and is the most recent sale in the immediate neighborhood.
I think it is a good test of reasonableness to support the value along with the other comps.
The subject as a comp adjusted in the middle of all the other comps.
I can definitely see how using a subject as comp could be problematic but in this case, I think makes more sense to have it in the report than to not.
But yeah, probably not worth the back and forth.....
