When it comes to interest rates, what goes down eventually must go up.
And as interest rates begin moving back up to more "normal" levels, that could spell trouble for home prices.
When the bottom fell out of the housing market in 2007, the Federal Reserve responded by pushing borrowing rates to record low levels. Those very low interest rates helped the housing market get back on its feet by making it cheaper for buyers to own a home. As of this summer, the average selling price of a single-family home has made up all the ground lost to the housing bust.
