Hello Croapino,
Since the owner is the builder, he does not have an emotional feelings towards the apartment. He'll consider your offer as a business offer, meaning you can try the lowest possible price and than will go higher if needed. it is a buyer's market and he understands that. Of cource he does not want to end up without making profit, so there will be his limits. If that is the condo I'm thinking about, than the owner is offering a bonus to the selling broker, which shows his interest in selling units.
Also, in New Jersey the agent, who showed you real estate and you was interested to buy it, this agent is considered to be a procuring cause and is eligible to the commission. The buyer who works with one Realtor and brings to the negotiation table another Realtor creates a whole bunch of problems. So, it is always good to choose the agent you'll trust before going to see the apartments. Of course, it never hurts to ask for advices, as you did!
Sincerely,
Sofia Ginzburg

I recommend your own realtor representing you. In some instances I can "tire kick" with the listing agent/ builder obtain info. AND placing an offer on the best interest of all parties. You don't want to low ball and offer which "insult builder" who could turn against you. Knowledge has power!

You could try the lower offer, but, all other things being equal, the seller will be more likely to accept the higher offer - wouldn't you? Sounds like you are still shopping for a Realtor, too. You should have ONE representing you as your buyer agent. I would recommend that you do not choose the agent representing the seller for this important role. Your buyer agent shoud research the market to determine what similar preoperties have sold for recently. Use this information to decide on your offer price. best of luck!
