The 15-year fixed averaged 6.71 percent, against 5.52 percent a year earlier. At 7.40 percent, principal and interest on a 30-year loan of $1,640,000 (80 percent of San Francisco's $2,050,000 median) comes to about $11,355 a month. At 6.27 percent the same loan is about $10,119, a difference of about $1,236 a month.
