Lawrence Yun is bad with math

What a flaming idiot. In recent commentary for a NAR's online real estate journal, TCLY had this gem of wisdom:

The word “correction” is a misnomer applied all too frequently in a misleading way. What homeowners and homebuyers are monitoring is principally where home prices have been and where they are headed. Nationally, the median home price rose 1 percent last year – that on top of the 53 percent rise during the five-year boom from 2000 to 2005. This year, the national median price is expected to fall 1 percent.

By any standards, it is an extreme stretch to call it a correction when a particular asset price rises better than 50 percent and then retreats one percent. Even a relatively large price decline of 12 percent in Sarasota cannot reasonably be considered as a correction when its local market had a 150 percent price increase during the boom. Let’s see, that is 150 steps forward and 12 steps backwards.

Take a look closely at Mr. Lawrence Yun's comparison about steps. If someone is on a stairway and at step 100, then you have a 150% increase in the number of stairs climbed. That would take them to step 250. Then suddenly they fall 12%, which would take take them back to stair 220. Which would represent an increase of 120% (from the original 100 stairs).

According to Yun, they would take 150 steps forward and then 12 steps back which would put the on step 238 (250- 12). 238 does not equal 220. Mr. Yun comparison is deceiving and bad with math.

Or heck, more importantly, how about this simple math: Buy a home for $500,000, it falls 12% in value or $60,000. You're screwed.
