Mortgage rates were unchanged on Tuesday; existing home sales hit their highest rate in a decade in October Tuesday produced more evidence that the housing market continues to strengthen, with the release of the National Association of Realtors' (NAR) October Existing-Home Sales. The headline statistic: Total existing-home sales rose 2% (seasonally adjusted annualized rate) from the previous month to 5.60 million, which surpasses June's cyclical peak and is the highest rate in close to a decade (since Feb. 2007, to be exact).

A three-year graph shows that the trend in home sales has clearly been improving: (Yes, the graph displays substantial volatility, but that's to be expected since these are annualized monthly readings, i.e., month-to-month changes are magnified. Furthermore, the graph would look a lot less volatile if the y-axis started at zero instead of 4.7 million.)

Nevertheless, prospective homebuyers need to focus only on their own situation and take the long view.
