Presenting Low Offers Without Offending a Seller

[Will Peters]

Hey BiggerPockets, 

I recently received a call from a recipient of my direct mail campaign about an off market property and have put myself in position to make an offer. I asked him the lowest price he is willing to take; however I plan to offer a bit lower than that. I have read a good amount of blogs on the subject and I am somewhat ready to offer that lower price. I plan to stay true to my numbers and hold fairly firm on my offer. 

Does anyone have any good advice about offering with confidence and the presentation of a lower offer?
