After slipping in June, NAR’s Existing Home Sales  for July jumped 6.5% unexpectedly from the prior month. Last month the results showed an slight decline (and were adjusted downward for this release) and the thinking was that the market is starting to cool off with the introduction of rising rates to the market in May. The bulk of May contracts probably closed in July, the likely basis of this most recent release. However it looks like the market continued to see a rise in demand in June, following the May bump in rates as people looked to get in the market before rates rose further.
Still, this month over month stuff is pretty ridiculous to place a lot of faith in. The year over year surge of 20.7% (non-seasonally adjusted) and 17.2% jump (seasonally adjusted)  is much more telling of the long term market change.
Here are a few other charts to review. Inventory is much lower than a year ago while showing some gains in excess of seasonal trends. Median sales price growth is off the hook. 13.7% YoY growth is not sustainable with flat income, tight credit and high unemployment and underemployment. Thanks goodness for rising rates.
