• "New Home Sales Plunge in Face of Surging Costs: As new home sales dropped 16.6 percent in April, house prices continued their relentless upward trend. The median price of new houses sold in April climbed to an all-time high of $450,600, up 20 percent from a year ago and more than 45 percent from April 2020. With the average sales price even higher than that at $570,300 and mortgage rates that have surged by more than two percentage points since the start of the year, many prospective buyers are effectively priced out of the market" - Source: [21]
