Not everyone is cut out to sell a house on craigslist, however. Some sellers just don’t want the responsibility. It’s that simple. They want to be free of obligations and that’s why they hire an agent to take care of everything. I believe that’s a big mistake. Getting involved by posting a classified ad on craigslist and replying to emails, texts and phone calls can really speed up the process of finding a buyer, if you do it well.
