Statistically, per freaknomics, a realtor selling their own home lists their house 10 days longer so they can get a better offer.

Levitt and Dubner found that, on average, self-listed homes stay on the market an extra 10 days, prompting the authors to hypothesize that agents might be a little more aggressive about their own homes because a 3 percent fluctuation makes a fair difference on the total sale price, but not that much of a difference when it comes to the commission.

ITT we're talking about "some months" (three? eight? more than a couple, anyway), not "10 days". The Freaks are just hypothesizing the price rise anyway; markets don't always go up.

Your link identifies the only actual service that realtors provide: objectivity. Houses are worth what buyers will pay for them. The realtor who can predict what price a house will fetch in the near term is providing a service. Permanent realtor's signs indicate failures of objectivity.
