The market has been cooling over time and prices plateaued for a while. Despite the consistent decrease in MAI, we’re in the Seller’s zone. Watch for changes in MAI. If the MAI resumes its climb, prices will likely follow suit. If the MAI drops consistently or falls into the Buyer’s zone, watch for downward pressure on prices.
