Working the deal directly w/the owner rather than w/listing agent

[Jose Lira]

Hello BP's!

This question has been drilling my head for some time and I would love your expertise.

Can I (the buyer) approach the seller directly to make the deal even though the seller already has a listing agent?

The reason why I want to do this is because I want to submit a deal way under the listing price. Probably around the 8% of it. If it makes any difference to the answer, the listing agent is also the property manager and the house is under a living trust from which the grantors have passed away.
