Home purchases fell through at a record rate in July, as high prices and mortgage rates gave more potential buyers cold feet. About 58,000 U.S. home purchase contracts were canceled in July, or 15.3% of all sales, according to Redfin. That’s more than 1 in 7 contracts being cancelled, the same rate as in June, which set a record high. July’s pace is up from 14.5% a year ago. Cancellations were most prevalent in Texas and Florida.
