DH and I are buying our first home. It's a leasehold flat on a ground floor Victorian conversion. Seller is refusing to provide insurance details of the other flat (solicitor says it isn't legally enforceable to make seller get these details). Flat we are buying was previously rented to the LA and it took months to get council tenants out. We don't think the current leaseholder has ever lived there so may not have met the occupants of the upper flat but have told us it owner occupied. We've been past and knocked a few times to meet them and ask them if the upper flat has damp (something we need to fix in the lower flat) but the other flat has never come to the door (though this is London and I know some people don't answer if they aren't expecting callers). I'm very nervous about it, the outside is freshly painted but in the survey, we had the gutters identified as in need of fixing and place isn't very well looked after. To be fair I think this is sellers fault as they are responsible for hallway and front and back garden. Has anyone got any advice? I'd really like to meet the upper flat before we complete the sale in case they are a nightmare and we can't get anything fixed (there is no ground rent and repairs to the exterior are supposed to be 50/50), many thanks!
