What I meant with what I said is that the home owner would be running negative, not me.
Example:
Home owner has a 4,000 mortgage, but willing to take 3,000 rent.
Tenant Buyer pays 3,000 rent.
Its the home owner who is taking a negative take.
Although it would be better if more than 30% of people exercised the option, its not bad...you still got the upfront option money. Them exercising the option is icing on the cake, and it depends on how you structured your deal: How much margin is there between your price to purchase the house with home owner, vs price for your tenant buyer to buy the home from you? How much rent credit is the homeowner giving you, vs how much rent credit you are giving your tenant buyer? How much option money did the homeowner want vs how much option money are you charging your tenant buyer?
What I'm talking about above is sandwich leasing.
The way you're asking the question, it sounds like you're talking about doing a lease option, as you being the home owner.
