I recently worked on an MVP for a Zillow-for-wholesale startup. As a curveball, our state passed a law restricting where and how these contract-to-buy sellers operate. So their workaround, after consulting lots of lawyers, was to provide a standardized LLC / Contract flow such that you’re no longer marketing a house for sale. You’re marketing a stake in an LLC, only that LLC has a sole purpose (a contract to option out a specific house).
