Mortgage interest rates are between 7.5% and 8% so people are hanging on to their houses and the new rates are pricing people out of what they want. This is creating pent-up demand so if the rates drop to around 5.5% or 6% you will see people jumping in. I saw where the difference in a 400K mortgage with today's rates equates to 1K in monthly payments from 2 years ago.
What we are seeing isn't a bubble but a delay due to rates people still have money in their pockets and there is a shortage of housing.
