The new home industry has gone broker crazy!
Realtors went from being a part of the buying process to help their clients make informed decisions, to being some sort of "get rich quick scheme" where Realtors are no longer acting on their clients best interest, but are acting in some sort of weird game.
It appears that some builders know this, and are trying to bring the process back to normal procedures, where some builders are using the Realtors and are seeing them simply as marketing expense, and seeing the commissions paid as a an alternative to interest on financing.
If a builder is playing this game, then play it back. If they are not giving you suites to sell, then take your business elsewhere.
