Seller finance contract question

[Kendra Penski]

Hi, I am in the process of purchasing a home from an owner who will carry the financing. I would prefer to keep title it in his name to prevent the increase in taxes if it were to transfer to me, however I am concerned about the legal pitfalls of this. Does anyone have advice on the best option? Perhaps a lease option? But even with a lease option how I would I protect from the owner getting a judgment or lien against the property? Thanks in advance for any suggestions!
