Well-priced properties continue to attract attention, and experienced REALTORS® are helping both buyers and sellers navigate these changing conditions successfully.”

CORNERSTONE cautions that average sale price information can help establish long-term trends but does not indicate specific properties have increased or decreased in value. The MLS® Home Price Index (HPI) provides the best way to gauge price trends because averages are strongly distorted by changes in the mix of sales activity from one month to the next.
