Lease Option Forms for Investor

[Steven Blanton]

Hi,

I have a lead based on some direct mail marketing.  This is a very nice house worth over $300K.  Sellers want to move to Pennsylvania but don't want to list with a realtor.  They called me from my mailer saying I would pay all cash for houses.  However, this is a retail house and therefore I offered to do a lease option with them and they are open to doing so.  I visit with them soon.  

I am looking to know which exact form I should use to tie the property up so I can find a tenant/buyer.  If you have a link or can IM me that would be great.  I have a couple of forms just not confident which one I should use.  Thanks in advance!
