MDA DataQuick. The San Diego firm tracks real estate trends nationally via public property records. The number of homes sold in February was the lowest for that month since at least 1994, when DataQuick's complete (all home types) Portland region sales statistics begin. The February total was the second-lowest for any month on record, behind the January 2009 sales tally, and marked the 36th consecutive month in which total sales have fallen on a year-over-year basis. Total Portland region sales have been the lowest on record for that particular month for the last 10 consecutive months.
