July housing sales across the country were the best on record for the month and the largest year-over year increase in two years, the Canadian Real Estate Association said Friday.

The Ottawa-based group, which represents about 100 boards across the country, said there were 50,270 units sold via the multiple listing service last month. That's an 18.2 per cent jump from a year ago. It also marked the first time sales had topped 50,000 in July.

"The difference in the resale housing market now, compared to the beginning of the year, is night and day and nowhere is this more evident than in the West," said Dale Ripplinger, president of CREA. "Homebuyers recognize that interest rates and prices have bottomed out, and are taking advantage of excellent affordability before prices and interest rates move higher."

A five-year fixed rate mortgage, the most popular product among consumers, is still available for under four per cent at some financial institutions. Variable rate mortgages, tied to prime, remain in the three per cent range and are not expected to rise until June. The Bank of Canada has pledged not to change its lending rate until then--but it is not an ironclad guarantee.
