ZeroDown is an affordable homeownership solution in the San Francisco Bay Area. Home buying isn’t just expensive here—it’s cost-prohibitive. So the majority of people end up renting, as a cheaper, but wasteful alternative. But what if there was an option between renting and owning? That’s where ZeroDown comes in: we buy the home you want. You move in and pay us a fixed monthly amount, building towards ownership each month. Purchase-credits* vest to you monthly, just like stock options at your workplace. ZeroDown blends the security of ownership with the flexibility of renting.
