Critique My Deal, Using Seller Finance on This Rental

[Jarred Black]

I have a seller with a well maintained 3/2 house with no A/C in a C neighborhood. Seller has very little equity. 52K mortgage on a house worth 60K. The seller is older and wants to downsize and move to a duplex. She only wants what she owes or for someone to take over the $623 payment. $138 principle, $485 interest (she showed me the bill). He mortgage has an 11% rate.

She's currently refinancing to get a lower payment. She's open to lease option or subject to for the new mortgage payment. My strategy is to hold it as a rental.The house will rent for $800 or $900.

I'm just not sure how I should structure the deal. Lease option or subject to? I'm concerned about the due on sale clause but i do want interest in the property.....looking for some good feedback BP
