The company expects to be valued at roughly $2 billion, according to one of the people, who asked not to be named because the matter is private.
Representatives for Knock and Goldman Sachs declined to comment.
Knock is led by Chief Executive Officer Sean Black, who was part of the executive team that took the home-listing company Trulia public during an earlier wave of housing startups. Black started the new company in 2015 with co-founder Jamie Glenn and it now operates in roughly 30 U.S. markets.
The company, which previously raised $600 million in equity and debt, calls its main offering the Knock Home Swap. It lends customers money to buy a new home while helping them sell their old one. The model is designed to help buyers make no-contingency offers that give them a leg up in competitive markets, according to Knock’s website.
Going public would help Knock compete with a range of deep-pocketed companies seeking to make housing market transactions more consumer-friendly. That includes Opendoor Technologies Inc.; Offerpad, which has agreed to go public through a SPAC merger; and Compass Inc., which has filed documents for an initial public offering.
These companies have benefited from a hot housing market during the Covid-19 pandemic, as low interest rates, tight inventory and the desire for bigger living spaces have stoked home sales across the U.S.
