I was loath to make time adjustments. If I am dealing with a $100,000 house or a $1,000,000 house, and my comps are no more than 90 days, any change over a short term can be no more than statistical noise. And since you had a seasonality impact (lower in winter and higher in spring) making a straight line adjustment for time seems a waste. In the end, prices would be up year to year by 4-6% but to say that 90% of that didn't come between March and June ?, well probably. But if prices were going up by 8% plus from say March to June, and then settled down by say 3% by fall.... ? Was the property really worth 8% more than a Feb. comp? Individually rarely even when the overall "trend" might declare so. I didn't adjust for $1,000 fireplaces, upgrades, landscaping, etc. and with the rarest of exceptions I saw no reason to make time adjustments in a market where a clear trend was difficult or impossible to establish. And I challenge anyone to pull 10 pairs of sales 3 months apart and derive a time adjustment. You need to look at a large data set or you are just sampling too small of a dataset to be mathematically significant.How do you factor time adjustments?
Depends on the other external factors, but with those out, I agree. The MV would be $3k above the last sale, in my B&W test book example. That still is above all the other closed sales, but probably not at the newer listing pipe dream prices. Pending sales, (if verified and found to be in sync with conditions of MV def), will be considered. How much...it dependsThat's what I do as well. I adjust from sales contract date not closed date.
Which leaves the question, if I make time adjustment up to and including the trend to effective date, and next round of listings jumps in price beyond highest adjusted most recent sale, how is that accommodated ? Am I missing something?
After applying a time adjustment result is a highest adjusted sale price . Unless the subject property is superior I cant' see how even an upward trending market results in a OMV above that.
I was trying to figure out how Res Guy and Mr Rex accomplish what they say they do, give strong weight to the pending and listings over the closed sales. Even if I apply a time adjustment right up to the last sale I can not see how a jump in price is made to a higher price listing assuming equivalent quality properties.
. Trends just don't stop.
