During the first quarter of 2019, 14.5% of the homeowners in St Louis with a mortgage, were underwater on their mortgage, meaning they were in a negative-equity position, according to data just released by ATTOM Data Research. As the table below shows, this slight increase follows a decline in the rate for the two prior quarters. The St Louis negative-equity rate is about one and a half times that for the U.S. as a whole.
