Flipping Purchase Options Contracts

[Scott Golden]

Real Estate Newbie here so please be gentle... I recently came across 3 properties, one with a privately owned lake that is land-locked by the other 2, that I'd like to submit purchase option contract offers on. My objective is to take these contracts and flip them to a developer. Is this possible? Is there specific clauses I need to have in the contract? Is purchase option the best approach? How do I protect myself from developers from back-dooring me on this?

Thanks in advance for any guidance here!
