I'm about to sign the "compromis de vente" pour an appt. There was a leak from the appt balcony above which slightly damaged the ceiling of my covered balcony (the appt I want to buy). The owner/seller declines any responsibility for his insurance, saying it's for the renters' insurance to pay. Both "my" appt and the one above are occupied by renters. Apparently, the syndic for the co-propriete declines responsibility also (tho I think there have probably been other leaks). I know it's not my responsibility but I want answers before buying. anybody have advice? Thanks..
