These days, I feel bad for my seller clients. It's a tough gig to be on market right now. To throw a bit of salt into their wounds, these home sellers are getting all kinds of "expert" advice from neighbors, co-workers and family members. In many cases, this pseudo-expertise conflicts with the counsel which you are providing to them.
To combat the ill effects of these emotional arguments, I have found that statistical data works very well. It is a perfectly valid question to ask, "Why hasn't my house sold?" and "What else can be done to sell it?" My response is to frame the question int he context of the sub market in which the house lies. For example, in Hinsdale IL, there are now 331 active listings of detached homes where 21 of them (or 6%) are under contract. That means that 94% of the houses are unsold. Moreover, if average marketing time is 218 days in Hinsdale and a specific house has been on market for 121 days, these use of the aforementioned market stats helps focus the question on the market and not on the emotional issue of an unsold home.
