Generally, no. Keep negotiation between the agents; that protects your leverage and keeps the terms in writing. In a normal transaction the buyer's agent communicates with the seller's agent on your behalf, much as attorneys speak through each other rather than letting the two parties negotiate face to face. On anything touching the negotiation, direct buyer-seller contact is essentially off-limits. Offhand comments to a seller, how much you love the house, why you are moving, what you would really pay, can weaken your negotiating position or create confusion about what was actually agreed. Routing communication through the agents keeps everything clean and documented. There are narrow exceptions. Once you are in escrow with contingencies released, a simple factual question, how a piece of equipment works or where a shutoff valve is, does no harm. Even then, loop in your agent. If you are tempted to go around your agent because something is not being communicated well, the better fix is to tell your agent exactly what you want conveyed. That keeps your interests represented and everything on the record, which is the whole point of having representation on the largest purchase most people make.
