Update:
As of October 30, is still not on the market. One of her neighbors is trying to sell though.
330 sqft bigger, 1 year newer, and an asking price the same as what Ms. Giles paid for her place in 2006 ($600,000). Oh, and it's been on the market for over 80 days.
Recently sold comparable properties in the Issaquah Highlands have gone for between $560,000 and $585,000. If Kim G. wanted to sell her home this decade without losing tens of thousands of dollars, it looks like she missed her chance.
