what are the benifits of a rent to own option? i want to sell my house and i have been noticing alot of people asking me that question.

A rent to own deal for a house is usually a scam.  Either sell, or rent.  Renting gives you an income, but you still need to pay for the costs of ownership.  Those payments can be tax deductible.  Selling gets cash to do other things.  The tax issues are more critical than the legal issues.  Meet with an accountant.
