Happy Nelson Mandela Day!!!

Hi everyone, I'm in the process of purchasing a flat in East Dulwich - 2 bed victorian conversion. It's a leasehold flat owned by Southwark Council. We've already had a few things come up in the purchasing process that has spooked us - for example S20 notice for a huge maintenance/repair cost bill which has now been dropped. So we are keen to do a bit more fact-finding on the leaseholder-freeholder experience. It would be great to know of people's experience owning a leasehold flat - and how often you are billed for unforeseen maintenance/repair costs. It would also be good to know if anybody has any experience buying the freehold from Southwark Council?  Thanks!  

Anyone have any? can collect no prob

They’re annoying in that they’re  usually in threes and dominate that busy corner. 

Maybe - or a sparrowhawk or buzzard? V fast
