What if homes could be printed instead of built?

In this episode, I sit down with Nan Lin, founder of 4DIFY and Kaizen Capital, who built California’s first fully permitted 3D-printed housing community.

We get into how he went from mortgage lending to real estate investing, and how that journey led him to launching a company that’s changing how we think about construction. Nan shares how they got local approvals, solved major problems in housing, and built something no one thought was possible.

If you're into real estate, construction innovation, or just love bold ideas—this one’s a must-listen.

We talk about:
-How 3D printing could solve labor shortages and reduce build costs
-What it took to get city and county approval for something no one’s seen before
-Raising capital from people who believed in the vision
-The mindset it takes to bet big on innovation
