Asking the seller to finance when the property is listed

[George P.]

Question to all RE Agents and Brokers out there - did you ever have to present an offer that required owner financing for the most of the asking price? Would you call before hand to inquire whether the seller will consider financing or just plain submit an offer to the agent?

As I can imagine most agents are trained to think in terms of CASH or Conventional Financing transaction. So how do seller's agents handle such an offer?
I am also thinking for those properties that had been listed forever, it might be the only chance for the seller's agent to get paid so they should be open-minded?...

Please chime in if you have anything to add to the topic.
Thanks
