Someone very kindly sent me the detailed listings for 106 residential house sales in Grandview so far this year (to 27 October). Being OCD, I had little option but to analyze them in some small way.
This graph is a chronological view of asking prices, sales prices and a moving average:

This graph shows that house prices are rising, but not very quickly (see moving average). The figures also show that the average asking price this year has been $1,201,955 and the average sales price has been $1,261,011 (5% above asking). The median asking price was $1,188,500 and the median sales price achieved was $1,206,900 (3% above asking).
Nine houses were sold at the asking price, 35 were sold for less than asking, and 62 were sold above asking.
I hope this analysis might be useful for those who can understand the figures better than me. My interest is in the historical record.
