My answer is kind of lame but it depends on the submarket. If the home is in glutted places like Eastlake or downtown condoland… A 5% hit may not get you there but after a few of them yes you will sell… If it is a place that is more desireable then yeah standing out from the crowd, and assuming your home is a true comparable would in my opinion get it sold much faster.
Yes you are right it is clumpy at the recent comp level. Sellers cling to 1 or 2% like it is make or break. I would agree that in most cases, it is a good idea to take a little bad medicine now to get sold and get out of dodge. Unfortunately most sellers have emotional attachments, feelings of entitlement that they should get what thier neighbor got in 2005, depression about the market and other disconnects from reality… as other symptoms that dictate a need for either psychological counseling or just a kick in the butt from thier high school PE coach who shouts get off the matt, take a salt pill, and suck it up and do the right thing!
