Hi all, DH and I are FTB and had an offer accepted just after lockdown eased on the housing market. Sellers haven't been great at keeping us updated but we've got things sorted from our end (mortgage agreed and arranging a survey). They've now contacted us to ask if we can delay a survey because they haven't found anywhere to move to yet, and they aren't willing to move out and rent anywhere. I.e. we have to sit tight and wait for them to find their perfect place for however long it takes.
Just looking for advice - how long is too long to wait? Are they being unreasonable?
