the more number of rate freezes that occur it will have a proportional effect of lenders shying away from extending more credit to new buyers, tightening their standards, and investors running miles away from any real esate related investments. Well, and if getting a loan is impossible for most new buyers it will have a devastating effect on home prices as is starting to happen right now.
This is to counter the silly argument that many make that goes since lenders are locking rates the market will not collapse. It is far too late for that type of thinking.
