Slight Seller's Advantage
Market Narrative
The market has been cooling over time and prices have recently flattened. Despite the consistent decrease in Market Action Index (MAI), we’re in a Seller’s Market (where significant demand leaves little inventory available). If the MAI begins to climb, prices will likely follow suit. If the MAI drops consistently or falls into the Buyer’s zone, watch for downward pressure on prices.
