FTBs, currently in the process of buying. Searches/enquiries are back, now waiting for solicitor to prepare the property report. The house is vacant, having been previously tenanted. Looks to be in really good condition throughout and the building survey showed up no significant issues.
I won't go into how, but through some detective work managed to find out who the previous tenants were and found them on Facebook. Was having a nosy through their photos to see if there were any of the house. Came across an alarming video from almost 2 years ago which shows the kitchen ceiling collapsed all over the floor (looks like below the bathroom.) No explanation in the comments as to what happened annoyingly. If it were a leak then I assume there have been no problems since then.
My question is, would you be asking the vendors what happened? That would obviously mean admitting I have been Facebook stalking people which is a bit awkward! It's also possible that they may not have even been aware as the tenant is a builder and might have repaired themselves. What would people do?
