Just discovered another correlation on Zero Hedge. If mortgage rates go up, lending becomes more difficult, so people stop applying for new mortgages. This means there is a negative correlation between mortgage rates and mortgage applications.
When mortgage applications go down, not a lot of homes will be sold. This means that home sales will go down. As suggested by the following chart, there is a correlation here between mortgage applications and pending home sales.
If it's true that interest rates and mortgage rates will go up, you can bet that we will have another housing crisis. Home sales go down. All those homes will be coming onto the market, while nobody wants them.
