I agree with Barbara, the ONLY thing is to drop the price!

there's only one activity that should have been done after the first 3 weeks and that's DROP THE PRICE.... or cut them loose before it expires...

Ask for a price reduction it has to be over priced to not sell in this market.

If the seller is not going to renew the listing with me, I would be careful in doing anything that will make it an easy sale for the next agent that gets the listing.

I would ask the seller to consider offering a bonus to the selling agent.

I would want to know why it's not selling. If the price has been reduced to the point of recent sales of comparable properties, then we can eliminate price on its own. If that is the case, then what else is there that is different in this home this is keeping it from selling? I would want to try to identify the root cause and then attack it that way. If it's a case where all homes are sitting on the market for extended periods, then that would be valuable information as well. There is always a reason why something isn't moving. I would try to hone in on that and then discuss it with the homeowner (to show my knowledge and openness) and then devise a plan of attack.

Debbie Reynolds - usually, I request the extension before going crazy over spending on extra marketing!

If you don't have gas in car, you can't go that far.....

I provide weekly updates on all listings I represent.  I provide updates on what is selling in the same subdivision, pricing, average days on market, the number of showings we have had, and even feedback from the agents.  That way, the writing is on the wall, the client is not getting hit all at once, at the end of the listing with the reality of the situation.   Many times if we are not on the same page from the start (namely PRICE), I make the choice not to take the listing from the beginning.  You can try becoming a premier agent on both Zillow and Trulia, the listing will be featured, getting more traffic in online traffic which should result in more showings, and hopefully more offers.  Good question Debbie Reynolds.

I would do more blogging on it, more craigslists adds, more open houses.  Everything I could.  Though I wouldn't wait until the last month to start all of it.

I would ask for a price reduction. Then beg the seller to keep the listing with me. Usually I don't have to beg, though. You know my market. Things move a lot slower around here. 

I would get a price adjustment. All the marketing in the world is not going to sell an overpriced home. Any home priced correctly, will sell.

I like to offer an incentive like free home warranty.

Probably the best thing is to consider a price drop if sellers can afford it. Or possibly ask seller if they can afford to pay part of buyers closing costs. Free home warranty if it wasn't already offered. I had one seller throw in free lawn care for 1 year.
