The U.S. housing industry has been witnessing solid demand trends for homes for the past several months. Despite supply-side challenges including rise in material costs, government regulation, labor constraints and higher prices, Americans seem to be interested in buying new homes. This is evident from the latest builder confidence reading for July.The NAHB/Wells Fargo Housing Market Index (HMI) reading unveils that sentiment among U.S. homebuilders for newly-built single-family homes inched one point down to 80 this month from the June reading of 81. Nevertheless, the metric is eight points above the June 2020 reading of 72.Despite the sequential one-point drop in homebuilders’ sentiment for July, the reading of 80 and above still signals strong demand in the housing market.Image Source: NAHBInside the HeadlinesSince the beginning of 2021, the economy has been grappling with strikingly high lumber prices, labor shortage and supply chain disruptions along with the second wave of COVID-19. Builders have been forced to announce price hikes, which are ultimately sidelining prospective buyers. This is evident from the three HMI components.The indicator that gauges present sales conditions dropped one point to 86 from the last month. Prospective buyer traffic also declined six points to 65. Nonetheless, sales predictions for the next six months, which gives an idea of future industry movement, increased two points to 81.Builders are still optimistic about the future growth potential of the industry. This is evident from the recent sales and starts numbers, which fell sequentially yet increased on a yearly basis. In May, the three significant indices — single-family housing starts, new single-family home sale and single-family existing home sales — were up 49.8%, 9.2% and 39.2% year over year, respectively. Also, the NAHB/Royal Building Products Remodeling Market Index was up 14 points year over year for second-quarter 2021, signaling residential remodelers’ high confidence in the markets served.Encouragingly, the Mortgage Bankers Association’s Weekly Mortgage Applications Survey for the week ended Jul 9 improved 16 points from the prior week, as the 30-year fixed-rate mortgage rate hit 3.09%. This indicates that home buyers are taking advantage of lower rates despite higher prices. In addition to these positives, private residential construction spending rose 0.2% in May from April to a seasonally adjusted annual rate of $751.7 billion. Also, the metric was 28.7% higher than a year ago. Specifically, single-family construction spending was up 0.8% in May from April and 46.1% on a year-over-year basis.Hurdles to OvercomeHigher costs, and lower availability of softwood lumber as well as other building materials are concerning almost every homebuilder.
