"Though mortgage rates have backed up in recent weeks, they still remain below their pre-pandemic tights and the backdrop for housing demand remains supportive."</p><p>However, Goldman said the ongoing boom in housing would slow in 2022.

"The consequence has been more buyers either upgrading, or entering the marker earlier than they had planned."</p><p><a href="https://www.businessinsider.com/us-home-prices-surge-further-low-housing-supply-goldman-sachs-2021-4#comments">Join the conversation about this story »</a></p> <p>NOW WATCH: <a href="https://www.businessinsider.com/what-if-jump-off-international-space-station-2018-6">What would happen if you jumped off the International Space Station</a></p> Click here to read full news..
