Last fall, LEX Markets launched an IPO for a partial share of a retail-and-office property in New York City that was open to investors with a minimum of $250 to put in. After similar "multiple successful IPOs," the company is taking a Seattle building public, according to a company press release.

The building, Solis, is in the Pine-Pike corridor and is another mixed-use development, this time combining multifamily and retail with a sustainability focus. The six-story building has "34,260 square feet of total rentable space: 5,960 square feet across three retail units on the first floor, and 28,300 square feet across 45 residential units for rent on floors two through six."

According to the company, it has a platform that allows people to "open a LEX account, browse opportunities in various asset classes such as multifamily and office buildings, and buy shares of individual buildings." Investors can earn quarterly income and trade shares on the LEX public market, although liquidity is not guaranteed.
