HELP!!! Anyone bought a house from owner using lease to own?

Beware of a Balloon payment in x years unless you are going to mortgage it before that.
Some real estate courses I have taken in the past,tell owners that a lease/purchase is a good way to collect more than rent and the tenants take care of the property like it is theirs and very few actually purchase the property.
Lawyer is highly recommended.
A mortgage would be a better choice,if it is doable.
Good luck,
