Take a deep breath & move on. 

Bless and release.

In spite of what the seller keeps telling you - you did not suck! Anyone that brought in that many people should turn around the situation & say 'why didn't ALL THESE people' make an offer? Then, you wouldn't accept an offer (could be good or bad).

It might be a difficult floorplan owned by an even more difficult seller ....

150 people didn't like the house? Really Mr Seller ....

See my response to the first time you asked this question... consider yourself fortunate, as these kinds of sellers are time wasters. (Maybe send a thank you note to the seller? )

You did your job, you marketed the property and brought showings and offers. There's no advice for unreasonable sellers better that what Andrea Moore said, other than just brush it off and keep improving your tools, education and closing gaps in your services. Every canceled agreement is a learning opportunity, painful as they can be.

Think about whether there is anything you would do differently next time and then move on. If 150 people saw the house and there were offers, but the seller wouldn't accept and/or negotiate, then it sounds as though this will never sell. Spend your time and effort on a house that actually will sell!!

First of all, it's sad to read that you were 'fired' from your listing - dang! - I'm sorry to read that . . .  Second of all, if I am reading you correctly, you wrote, 'couldn't generate an offer my seller would accept'.  So . . .  there was at least '1' offer!  If negotiations could not 'work this out', maybe (just maybe) someone is being unreasonable, i.e., your seller.  They are dealing from 'emotion' and feel their home is worth more than the market will bear.  It's only 'worth' what 'a buyer is willing to pay', just saying!  We cannot make anyone accept a price, even with Comps to prove their Asking Price is too high.  Price, as they say, is usually the bottom line - even over that 'awesome view' and over 'no updates on a resale'.  Third of all, 'difficult floorplan' is subjective in most cases - some will love it and for others it will not work.  You did have a ton of traffic, for sure.  I will read replies below, because I know there will be some great advice in them.  For me, you did nothing wrong, though our buyers and sellers can fire us.  You know, that you did everything that YOU could.  Hang in there!! 

Move on, life is short. A

Same advice - deal and grow from it and move on!

You should not get discourage due to a home seller was not happy. Good luck.

Move onto something that is more worthy of your time.

With 150 showings, how many offers? My new listings i can see about 10 buyers and 5 offers in 2 days. You have to look at the offers and that most likely is what a buyer is willing to pay. If the seller is not realistic, nothing you can do but move on. 

Move on. Perhaps easier said than done. 

Move on.

Time to move on. You did your best. 

Just shake it off, you did your best. It happens to the best of us.

Don't waste a minute more asking what OTHER PEOPLE THINK!

Grow a thick skin.  Get over it.  Move on.  

If you have to worry about this, you may want to reconsider your new career...trust me, worse things will happen.

Eve

Yes, move on.

You didn't say no offers just no offers the seller liked but with 150 people seeing a property with the current seller's market and the offers weren't good enough points to two things being most likely.

The property doesn't show well

and or the seller is being unrealistic

But as Ken Jones, ASA, SCGREA, CRES said move on learn from it figure out what you could do differently next time and come out of the shadows no need to be anonymous ;-)

They did you a favor !

Thankfully things like this do not happen often. They do happen. Know that you did your best. You had a "difficult" seller with unrealistic expectations ... love yourself, let it go, move on.

Sounds to me like you have an unreasonable Seller, or the house did not show well, or the price was too high, or all of the above.  If you know you did your job, and by the sounds of things with 150 showings you did your part.  Leave it go and move on... It wasn't you.. 

Your job, as a real estate agent, is to market the property and get feet in the door.  You did that.

Another part of your job is to help price the property appropriately.  It appears you didn't manage that.  Did you push for a lower price??  Did you press for a price reduction??

A bad floor plan is always difficult, so don't beat yourself up about losing the listing.  At least you got your face in front of 150 buyers!  Use that to your advantage and move on.

You learnt that it was a difficult floor plan and one that buyers did not like. As you go on in the industry you will lose more listings, we all do. Yes, it hurts, but you move on. And the next agent they list will may very well encourage them to lower their price which they refused to do with you. We all learn from every experience and put it to greater use next time. You generated traffic so you did something well so congratulate yourself for what you did right and evaluate what you coud have done differently.

Some will

Some wont

So what

Next

It's just part of the game. Eventually the seller will figure out what they need to do to get it sold. Don't waste your time worrying about it. You're better off working with sellable listings.

It happens.  Don't worry about it.  Along the same lines as Nina Hollander ... I would send a note to the sellers thanking them for the opportunity and saying you're sorry you weren't able to secure an acceptable price for them.   That's it. Don't ramble and make excuses.  Just wish them well. You never know where that "high road" act could lead to in the future. 

Use this as a lessons learned opportunity. Stand up, brush youself off and move on.

It happens to everyone at some point in their career. If you cannot identify something you could have done better, it's best not to dwell on it and move on. I've seen sellers hire 3 or more agents only to fire them. 

Next! NEXT!
Rejection is protection. In some way this is fortunate for you, something better is coming, it's not about you, the good news is you know the property and if a buyer comes along with criteria that matches, boom!

Move on. 

But next time try to incorporate a price reduction schedule. Floor-plan can be a big disadvantage for the property since it can be very expensive to fix.

You did your best on bringing showings and it sounds you were working with a difficult seller, so just move on and put your energies on other clients.

  What Nina Hollander said.

onward and upward....

Answered.

Who are you?

Allie Angeloni nailed this one!

Unfortunately, this is a part of the business.  Move on to a better listing and a more reasonable seller.

Duplicate perhaps!

I'd say, be happy!

You must have promised to deliver something that did not happen. I tell clients what my expectation. If home is priced correctly your ex client should have ample offers to consider.

Talk to your broker.

Great answsers are here.

Agree with all answers

With a property like that, it's always better to be the "second" agent because you, the first one, have already "softened" the seller up. Bet the seller will take something less next time around, might even end up being less than what was offered while you had the listing.  I have seen it all. It smarts, but let it go.

It is tough when this happens, and we all have been there.    NEXT!
