Ups and downs, ups and downs of Parkway Villages

I have a listing in Parkway Village and to suggest a price I looked at not just the sold prices over the past 6 months and the current competitive houses that are for sale, but also the price history for the subdivision to see where things were selling and where prices are going.  Instead of plotting averaged years or quarters like I have in the past for other areas, I plotted individual sales for all 3 and 4 bedroom houses in the subdivisions.  In excel I fit a curve through the dots to make the price trends more visible.

It appears that the price per square foot and sold prices peaked in the beginning of 2015 soon after the price of oil began to crash.  Since this neighborhood is in the energy corridor, most of the potential buyers probably work for one of the energy companies. There are some outliers, but it appears that price per foot peaked back in 2008 near $150/sq ft, then decreased down to the $125/sq ft back in 2010, then rose steadily to around $175/sq ft in 2015 and since then has decreased. 

It is pretty interesting data because each dot is an individual house, and there are two recent sales at near $200/sq ft, if it weren't for those 2 houses, the trend line would pass much closer to $155/sq ft.    The minimum price per square foot increased from $110/sq ft to $160/sq ft from 2010 to 2015, and now has come back down to $150/sq ft on some of the most recent sales.  We could probably use an increase in oil prices and oilfield hiring to get prices moving up again, but to sell this property it was priced below the lowest price per sq ft in the area for sale, below $150/sq ft.  Come and see it, it is a "go" on Supra.
