Curt Abramson from Bailey Properties here. I'd advise you to identify the homes you'd really like to consider, and then put together a strong offer that includes an option agreement. Just like any other offer, a lease-option has to meet the needs of both buyer and seller. Most sellers would prefer not to sell under these terms, and if you look specifically for one that has already decided to do that, you are limiting your pool of available homes. Sometimes, it's because the home won't sell any other way!
If you aren't working with another local agent, I'd be happy to talk with you about what a strong offer would look like, and what kinds of homes you might consider. You can contact me via my website, noted below, or directly via phone at 831-251-4718. Good luck with your quest!
