The only way to truly know whether or not a seller is open to a lease-option is to make an offer on 1 or more properties in Palmyra with a lease-option.
Besides performing your own due diligence on the seller and the property, another thing that you or the seller could to help protect both of your interests is to establish an escrow servicing account (ESA) to handle processing your payments. The ESA agent accept your payments, pay the rent/mortgage, and pay the seller the remainder of the proceeds. This way you ensure that the underlying mortgage will get paid. This also protects the seller too, because the ESA company will notify him/her if you're late or simply haven't paid.
