The sales price of a Avalon Park house is affected by its size. Looking at price per square foot gives a partial adjustment for differences between houses. Furthermore if you look at the average size of a Avalon Park house sold you will see that it varies with time. Part of the variation is due to the random nature of which houses are being sold but there tends to be a increase in the size with time because when a house is replaced with a newer house, the newer house is almost always larger.
