I'm already seeing new type of financing available for homebuyers in response to interest rates - think seller carry, Australian mortgages, and yes ARMs. Life finds a way and the market responds to keep deal flow going. The past few years were very special in history, and today's 5.5% 30-year fixed is still easy money by comparison.
re: That's cute but it's true - there's always someone looking to make a return. There's always someone who wants to start a business. You and me - we may not have money in our pocket, but there's a lot of money in the world and there's always someone who sees opportunity where others see danger and who will move money around to the corners that are generating a return.
