I use a realtor (my wife) to market and list our properties. The reason is that the coverage you get from the MLS and Realtor.com. The best way to sell a house quickly is to make sure it is the best product for the best price.
If you are listing it yourself it is because you want to save on commissions, so NO you don’t want agents to bring prospective buyers.
…yeah, I can see how that is justifiable, being that the buyer will be getting a great value for their money and with the buyer assistance the little bit extra purchase price shouldn’t be a “financing” problem/issue!! Making the deal “turnkey” should still work even at a higher asking price.
Depending on where you are and what you are selling, I would not pick one or the other in terms of marketing. Rather I would pick BOTH and do everything you can to get your properties sold ASAP…remember that holding costs can sink a deal rather quickly.
