Our home is not listed yet, but we had a couple go through with their real estate agent twice last week--first on Thursday evening and then around noon on Saturday.
The agent called me on Saturday evening and said they had some questions, including what our timeline is and the age of furnace, ac and roof. They are currently living with a family member, and I think are eager to move. I called her back with the info (all dates were 1989-1994), and she said she would talk to them on Sunday and get back with me--wanted to know our schedule for that day since she didn't want to interrupt anything. She also said she thinks an offer is likely.
We never heard from her. I saw her this morning at preschool dropoff, and we just said hello. I assume she would tell us if they aren't interested so that we can go ahead and list. How long would you wait? Do you think they would have already made an offer if they were interested?
Re: How long to wait for an offer?
If they are no longer interested, then you probably won't hear from them. I would list this weekend.
