There's a roughly 3.6% spread between the purchase price appreciation schedule and purchase credit schedule, no option to extend the lease past five years, and a two-year minimum for accumulating leasing fees. This points pretty strongly towards partnering with a "hard money" lender willing to put up balloon loans and happy to collect either the above-market-rate interest or the property in lieu of repayment. It's likely arbitraged so that 100% of the risk gets offloaded. The appreciation schedule on the purchase option pays for the excessive interest demanded by lenders happy to take possession of property in downturns.

Furthermore, Zerodown is structured so that it will never go through the foreclosure process. They own the property and lease it out, so the worst they'll need to do is an eviction.
