In New York both parties should have an attorney to draw up the contract and lease.
In a quickly recovering sales market I would think it will be very difficult to find such a transaction. A year from now who knows where sales prices will be? In a real option to buy the sales price terms etc will all be in the contract up front.

For example lets say Market rent your looking at is $2500 dollars. You pay $3000 dollars a month.
Only $500 dollars per month would be counted towards your down payment
Hope this answers your question
