ddOwner finance rate of interest

[Elizabeth Matos]

Hello Everyone, 

   I have been very busy with my real Estate class.  And just in case you are new my last post I suggested if you would like to get educated you might try the community colleges in you area.  Many have real estate classes and will not cost too much.  Today I am creating a bid for a duplex which will be owner financed.  I am wondering how I know what interest rate to offer with the bid.  How do I determine what to offer in the case of terms and conditions.  The property is in Riverside Ca.  asking price 349,000.  I will offer asking price but with that what should I offer as an interest rate?
