I know my house buyers slightly as they were parents at the school my kids attended until recently. They found my phone number from a former school year group parents WhatsApp group and set up a group chat with me once they made their offer (though estate agent — it’s not a private sale). Anyway, my house is now empty and it turns out they somehow presumed they would be able to have early access before completion to have floors sanded and walls painted, My solicitor strongly advised against this as it brings various risks, not least that I’d ultimately be liable for any accidents or damage. I said, on an awkward phone call they asked for with me, sorry, no, I’m not comfortable with this. They said it will be hard for them to do the work with kids and furniture. Seems like they’d assumed my goodwill in this. AIBU?
