” Take, for example, my neighbor, who has his home back on the market as a FSBO. Third time’s a charm, right?”
Or take my neighbor, who sold his quickly, for a higher price than anyone else on the block expected, and and kept the 24,000 he woulda spent on commissions.
Tautologically, if the neighbor didn't price his house to sell, he didn't really want to sell it. When he wants to sell it, he will.
For buyers or sellers, there are costs and risks involved with using an agent, different ones with doing it yourself.
