"To get the deals done, banks have turned increasingly to unregulated mortgage brokers, who now account for 80% of all mortgage originations, double what it was 10 years ago, according to the National Association of Mortgage Brokers. In 2004 banks began offering fatter sales commissions on option ARMs to encourage brokers to push them ... The problem, of course, is that many brokers care more about commissions than customers. They use aggressive sales tactics, harping on the minimum payment on an option ARM and neglecting to mention the future implications. Some even imply verbally that temporary teaser rates of 1% to 2% are permanent, even though the fine print says otherwise."
