total market performance yaer to year comparision

below is the relationship by year of active ,pending  closed sales. based on the rate of sales so far this year and the amount of the market that occurs in the last third of the year it indicates unit volume for sales should end up approximately 10% below last year. i not sure we will get quite that close because last year we had the tax credit rush in September and October which we will not have have this year. which would leasd me to belive a lower rate of sales through the end of the year
