So, only about 1/5-1/4 of home buyers are cash buyers. Everybody else has a mortgage. Typically (AFAIK), borrowers can lock a rate for 60-120 days.
Let's use the TYX as a proxy for mortgage rates.
So if we look back 120 days, we can see that with each passing day, home buyers are going to be locking higher and higher rates, which means lower and lower prices they're able to afford. Obviously, some had shorter locks, too, and otherwise had bad timing, but the bottom line is that until very recently, there were a lot of buyers with low rate locks. That's changing as I type.
I think within the next few weeks, this should begin to really bite and a few weeks further out, should cause real estate to hit the wall. Between that and a miserable stock market, a lot of excess cash could go to money heaven. That could take a lot of pressure off the Fed.
