@Brian Willie- If you're going to do it for just one property, it's probably not worth the legal cost to get a lease option agreement drafted, but if you're doing it for several, it may be. Below are some war stories I have dealt with pertaining to lease options:
1) Lease option contract was signed and left at home. Home burnt down with the lease option. Landlord then denies there was ever a lease option agreement. Landlord and tenant end up in expensive litigation for years. Takeaway: a copy of the lease option agreement needs to be put somewhere safe. It possibly could be recorded depending on the state.
2) Tenant pays the lease option premium, then stops paying rent. Landlord tries to evict, but tenant sues in civil court for breach of contract, stringing out the eviction process for a year while not paying rent. Takeaway: it may be harder to evict the tenant with a lease option.
3) Tenant thinks she's signing a lease option agreement. Landlord thinks she's signing an installment sales contract. They wind up suing one another. Takeway: it's important to have a well-drafted lease option agreement from the beginning.
