Almost two years after Tony Hsieh’s family filed 100-plus sale notices in court, his estate has formally decided to sell “some” of the massive Las Vegas real estate portfolio he assembled.

Hsieh’s estate announced Friday that it “decided to initiate a marketing process and offer for sale some of the real estate it holds in downtown Las Vegas to allow potential new owners to carry on what Tony started, accelerate momentum, and continue to spur development and growth in the area.”

It said the late tech mogul’s side venture DTP Companies “requires a substantial investment of new capital and a significant increase in new development in the downtown area,” neither of which the estate is “positioned to undertake at this time.”
