I did a number of VF deals years ago - more than 10 years now.
One of my tenants was able to purchase a $200,000 property from me for $140,000 because of rapid capital growth. I made about $20,000 and he made $80,000

It will no doubt involve options. Doubt you will find a vendor willing to sell you an option for $1 too easily.
BTW, I seen Rick Otten has a book out on this topic.
