I have agreed to it anyway so its a bit of a non issue but having not sold a house before I wondered if this was normal or perhaps they just wanted to snoop. Its only been on the market for 24 hours and I've got 3 viewings booked in.
They are apparently in the same village and haven't got theirs on the market as they couldn't find anything they liked until now but their house is ready 'at the click of a button' according to the agent. I have until now, refrained from viewing other properties as I didnt want people to make a special effort to tidy etc (being pregnant and having a toddler i know how hard this can be!) if I'm not in a position to make an offer. Perhaps I should revise that and go and view some.
