Builders are taking matters into their own hands, and the high interest rates and falling demand are forcing the issue. Rate buydown programs and other interest rate specials are on the rise in the new-construction market. Builders are making concessions to their bottom line in order to keep prospective buyers in the game. Builders are offering programs to lock down interest rates, guaranteeing rates or offering a few years of discounted interest rates so buyers can later refinance at a better rate. The saying “marry the home and date the rate” describes the thinking behind the move. According to the vice president of operations for M/I Homes Detroit, the company has spent millions to secure enough funds to provide several dozen loans. They’ve done this three times since this summer.  The company takes a 4 to 5 percent hit on the purchase of a home. Robertson Homes has taken between 1 1/2  and 2 points off a fixed-rate mortgage by contributing funds to the lender up front.
