You've got a fiduciary obligation not to reveal the seller's bottom line if it differs from the asking price unless the seller authorizes you to do so in writing.

I respond -- study hard, take lots of practice tests, do well on your state exam. 

make an offer, and you'll be the first to know!!

I would say, "I know the seller would seriously consider an offer that matched or exceeded the listing price". I said this to someone yesterday in fact. 

As the seller's agent you cannot reveal that unless you have something in writing. Make an offer and let's see what happens!

Just tell them to submit their best offer.

You have the answer as stated by Candice A. Donofrio and Carol Williams .

If you are licensed you know the answer to this question.  There are no duties owed to the customer... only to your client. 

This should be one of the top answers you have in your real estate tool box. I always smile & do the corny 'they will take the list price I bet'.

I have a standard line for that: 

"I know that the seller would accept a full price offer, but why don't you put your offer on paper, and we'll find out together?"

  The Seller is asking X dollars.  That is the price.  Do you want to write an offer?

I had this often. My response is, "The only way to know is to write an offer." 

I never ask my clients this and if they volunteer it, I tell them I don't want to know.  As long as they would accept list price if it were the only all cash offer, I want to leave the options open.  Things change.  Even if they gave a number, they may reconsider based on a new comp, change in their situation or a home they want becomes available.  

I have no idea, it will take a written offer to find out. even when a Seller states they won't take a penny less than "x" doesn't mean you know until they has an offer in front of them, how long it has taken to get that offer, condition, other financial considerations going on in their life...things change.

You follow the instructions of the seller.  Period.  
If you don't know - say you don't know.  If you do know, and you are not authorized to discuss, then say you are not at liberty to discuss it. 
If they are interested, make an offer and let the seller respond. 
And if it were me, I'd say, find someone to represent you because I will not. I represent the seller and do not represent buyers on my listings. 

If the seller has authorized you to provide his bottom figure, you can do this.  If not, they you say "bring me your offer and I will see what the seller is willing to do with it."

Many great responses!

I'd say "Gosh, I don't know. Write an offer and the seller will respond."

Seems like there's a consensus on this one- you don't give that information away. That's Negotiating 101 right there. 

With all of that said then you also know "confidentiality" is part of your fiduciary duty. My listings will generally have minimums prescribed by the Seller although I will always ask Buyers to offer the best they can afford if they really want the home. Whether it passes muster remains to be seen.

Mr. buyer you need to get your own agent, I represent the seller.

Present your Offer and we'll see how the sellers respond!

The answer is simple: "I don't know... write us an offer and we'll take it from there." If you represent the seller you cannot legally or ethically compromise your client's negotiating position.

They always ask, but you do not have a Cristal ball to guess it. Yes, if you know the exact number, it will be easier for you to see if there are any chances for them to meet without disclosing the actual number.

I'm not sure, just how much would you be willing to offer?

I'm pretty sure they would accept a full price offer.

"...Submit your offer and we'll find out..."

"Place an offer and find out!" After all, you can't speak for your client...

They might accept the asking price, why dont you start there and see what happens.

Just send the offer - and the counter will tell you what that number is!

My loyalties are to my client which means what I know stays with me and my client and the only way the buyer will know for sure, is to make an offer and see where it lands.

You do NOT know what the seller will take, that changes hour by hour sometimes

This is the eternal flaw of dual agency. Like Barbara says, "let's write an offer and find out!".

The response to a 'how low can I go' offer is absolute silence.

The answer to 'no offer' is always NO!

Maybe, dear buyer, you need to retool your thinking and strategy. The way you are thinking means you will NEVER get in the game.

Question was answered with great answers.

Great answers, I agree.

Make an offer

Put it in writing and the Seller will respond

My response is the asking price is an invitation to bid. The seller is likely to accept a full price offer with few contingencies. What are your thoughts?

If I am the listing agent, i answer it like i do every other time. That the buyer should make their best offer in writing, accompany a pre qual letter and the seller will promptly answer whether they are willing to accept of counter you with what they will accept

I always respond that I think they will accept the listing price, though it's not guaranteed.

That should be a good class discussion.

Your answer: write your highest and best. 

"The lowest I can say they will accept is <insert list price here>, but if you'd like to make an offer, let's put it in writing and I will present it for consideration along with your pre-approval letter or proof of funds."
