In order to know if you would qualify under the structured scenario, I would have to know more about both you and your parents to be able to determine if you can qualify for the loan.
If you'd like, give me a call and we can review your options.
Ted gave a great answer below.
If your parents don't have the required minimum to purchase the home and you cannot be added to the loan and have your parents listed as non-occupant co-borrowers, then my advice is for you or your parents to save up the minimum required down payment if you want to buy a home.
Seller financing (owner carrybacks) usually have higher down payment requirements and usually have higher interest rates. Also, assumable loans still need the new buyers to qualify for the loan and without the right qualifications, you cannot assume the loan.
Discuss this with a mortgage banker/broker, like Ted Canto.
