Lets see...hmmm, not a searchable feature on my MLS. Ok, now what? The subject does not have a hot tub, spa, built-in or otherwise. One of the comps did. Ahhh, ok...let me do a grid and see if I can determine an adjustment by paired sales analysis.
Holy crap, Batman...
I did it 25 times. Took me 3 days and guess what? Can't seem to prove a buyer paid anymore for the comparable with a hot tub than one without a hot tub. Can that really be true? Doesn't a buyer just salivate when thinking of all that fun they will have in that hot tub...especially if the wife looks like bubbles?
But, but...Mr Mike, The property owner spend $5,000 for the hot tub, installation, and all the wiring and plumbing. Isn't it worth something? Ahhh...yep, and I call that "value in use".
Would a lender get all bent out of shape if I made a $2,000 negative adjustment to a comp that had a nice built-in hot tub? I doubt it. Would the state give me grief if I didn't have paired sales analysis in my work file to prove the adjustment? Yep...at least in my state.
So, what is the solution? You be the judge of that. As for me and my shop...I think I just might not make an adjustment I couldn't prove.
