Owner Finance Deal

[Hank Oyler]

I have looking for a decent rental opportunity for last couple months.  This weekend i came across a sfr that is selling for $50,000. Unit is currently rented for $900 and tenant wants to stay. In talking with owner he is willing to owner finance. Just wants to get out from it, including owner finance.  I would appreciate any advice on how to handle this deal from here.  Looking for creative ideas? Thanks in advance.
