Mortgage lending is an opportunistic business and when business declines, the instinct is to consolidate to become more efficient, and that is what we are seeing.
Even if interest rates weren't rising, home prices are very high relative to income. So, people are getting priced out and rising mortgage rates are making it worse.
It's pretty clear that housing is slowing. Rising mortgage rates and the very fast rising homes prices are constraining home buying. Homes are still considered affordable, but not as much so as a year ago.
