Cash vs. trad. vs. owner financing offer basics

[James Housego]

Trying to structure an offer to a seller with three options: cash, traditional financing and owner financing options. If the property is listed for 159k and could be wiggled that down to 150 with trad. financing, what might my cash offer and owner financing offer be? I've heard cash offers should be 60 cents on the dollar. Do owner financing offers usually come in above traditional (without getting into the weeds of interest rate etc.)? Any help, including ballpark estimates would be appreciated. Thanks.
