What an amazing coincidence; City of Greensboro real estate values spiked before revaluation and then went back down.

"Total taxable real estate declined nearly 9 percent in Guilford County from 2008/9 to 2011/12 (based on equalized values) while the other major cities in North Carolina had a slight decline or grew the tax base.

Year End City of Greensboro Median House Values from 2013's State of the City Report

2007; $143,500
2008; $143,100
2009; $143,800
2010; $149,300
2011; $151,300 - Guilford County real estate revaluations occurred as of January 1, 2012
2012; $140,300 - Representing 2012 year end values from 2014's State of the City Report"

From 2014's State of the City Report;

"Given the substantial declines in home ownership levels in Greensboro from 2011 to 2012, ...the median house value decreased by $11,000 from $151,300 in [year end ] 2011 [when Guilford County's Real Estate Revaluation occurred],  to $140,300 in [year end] 2012.

...this directly contrasts with a four year rise in house prices from $143,100 in 2008 to $151,300 in 2011.

The overall tax base in Guilford County declined -0.2% from $37.1 billion in 2011/12 to $37.0 billion in 2012/13. Much of the explanation for this slight decline is likely attributable to the 2012 revaluation [as of January 1, 2012, which was a day after the end of 2011, as noted above] and subsequent appeals of value."
