Maybe I missed an earlier and accepted definition on this site regarding what exactly “20XX pricing” means, because I don’t understand precisely what is being referred to. For instance, in 2004 the same floorplan sold in my neighborhood for as low as $386K and as high as $459K. So what is 2004 pricing? The average? The median? The high? The low? As you can see in this one example, how you define “2004 pricing” makes a big difference in the analysis.
