The sticky point will be the terms you agree to.
While the state law did not prohibit executory contracts, it did make them very risky for seller/landlords. You must as the seller comply with the provisions of the law or risk losing every single penny the renter paid to you.
Realtors are not allowed to write up contracts that are executory (meaning not closed/executed within 6 months). Only an attorney can write the contract between you and the renter/buyer.
We handle such requests all the time. We have attorneys who can put together something that makes sense, protects you as much as you are protected from a renter, and doesn't cost an arm and leg - just an arm.
You need to sit down with a professional and discuss your needs first.
