Yet despite a market full of reluctant buyers, sellers are not under pressure to drop their prices. Almost 60 percent of households have an interest rate below 4 percent, according to a study published in the Journal of Finance; selling would mean trading that low rate for a much higher one on a new purchase. Not since the 1980s, when borrowing rates soared into the double digits, have so many Americans been locked into their mortgages, said Lu Liu, an assistant professor of finance at the Wharton School at the University of Pennsylvania, and an author of the study, describing the conditions as “unprecedented.”
The implication of the argument above is that people do not want to leave a low mortgage rate for a higher mortgage rate. But this is not necessarily a new situation; mortgages rates go through cycles. Is this just about mortgage rates or do low mortgage rates make it easier to not move due to other reasons? American geographic mobility is low.
Presumably, many people have a price or conditions under which they would move even with a low mortgage. What exactly would it take: a new job that offers 10% or more compensation? An unbelievable housing deal elsewhere? A perception that where they are does not have a good future?
Imagine this scenario: mortgage rates slowly decrease in the next year or two, getting back to 3-5%. Would this significantly increase mobility? It could put more homes on the market as homeowners might be more willing to see what they could get. But would this significantly change the calculus of moving in the first place?
My suspicion is that this is a bigger issue that just mortgage rates. With higher rates, some people will still move: those with resources and opportunities they feel they cannot pass up. With lower rates, more people will feel they could move. But geographic mobility is already low compared to the postwar years and it could take a lot more than mortgages to change this.
