Creative finance lease option

[Joshua Bailey]

Currently looking at a 12 acre property with 6 cabins. The owners still owes 200k and selling for 375k. Seller finance isn't an option due to his lean, although he said he would seller finance if I could pay his lein which makes me think he may be open to a lease option. How many people have created a lease option for deals like this? What is a typical down payment for and what terms do you usually see. Just want a better idea before I present another offer for lease option.
