Yeah, these are re-runs, but some questions remain un-answered. Care to share?
Who are these mystery people that think the adjusted values of the comparables or listings are indicative of sales price of the comparable or listing? Do you have HOs suing someone when they find out your adjusted value of their sold comparable is lower than what they paid?
The arguement against applying a SP/LP adjustment is akin to saying don't make Time Adjustments to the sold comparables, someone might confuse your adjustment to that particular comparable to constitute an appraisal of that particular comparable as of the effective date of the appraisal.
So who are the users of these reports that are so misdirected and (step back) "mislead"?
The adjustments to the sold comparables are based on things that have happened in the past, known facts, to bring that sold comparable up to todays effective date of the report.
The LP/SP ratio is trying to say what will happen in the future, that is the difference. The future is unknown. Why not use the average or median days on market to tell them when the listing will receive a contract?
As to your first question, in real life, you know darn well the reason the clients want to see this adjustment on the grid is so all the adjusted values line up with each other on the report. When doing that, they are in fact using that adjustment as a prediction to equate the listings to sales.
That is not for me, sorry, no sale here. For those that do, have at it, you will not burn in appraisal h*ll, but you are leaving yourself open for credibility issues later on down the road if any of your reports come into question when all the facts of those listings are known.
As an example, lets say you use three listings on a report. Your LP/SP ratio is 95% for the market. So you apply a 5% adjustment to all of them. Two years down the road, for some reason this report goes to court. The first listing ended up selling for full price, the second listing ended up selling for 90% and the third listing expired with no offers. It is right at your 95% ratio, but none of the adjustments came close to the actual real life result. The opposing attorney can use these three examples to question your credibility. If your adjustments on these three listings were so far off, how hard would it to believe that your subject value opinion is just as far off...
