The loan officer who gets you your mortgage? That's a different story. He doesn't want you to get a 30-year-fixed loan. You're a "deadbeat" to him, if you do. Very little commission. He likes those ARMs that you have to refinance every three years. A loan officer makes as much or more than a real estate agent on any given transaction. And it is undisclosed to the Buyer. (The Realtor commission is right on the closing statement.)
In Chicago, a real estate attorney makes about $550 on the closing of a home. Regardless of price. He doesn't give a tinker's dam what you pay for it.
