The first indication that a buyer probably isn’t serious about shopping for a home? It’s when they came to the showing by themselves. A serious buyer who is ready to buy a house should have a real estate agent by their side. Since it’s the seller who typically pays the buyer’s agent and it costs the buyer nothing, knowing that they enlisted free professional help is enough to show that they’re motivated to start putting papers in motion.
The real estate process is complicated and demanding, and it requires real work from experts. Their knowledge of the housing market and their insights about the listing greatly contribute to a fast and successful transaction. Unless they are agents themselves, very few buyers are capable of negotiating and dealing with all the legalities and paperwork. Hence, a buyer who comes for a viewing without an agent is probably not serious and just window shopping or getting a feel for the market.
