We study the compensation that borrowers pay to mortgage brokers for assistance from application to closing. Two findings support the conclusion that confused borrowers overpay for brokers' services: (1) A model of effective shopping shows that borrowers sacrifice at least $1,000 by shopping from too few brokers. (2) Borrowers who compensate their brokers with both cash and a commission from the lender pay twice as much as similar borrowers who pay no cash. ER -
