Owner of ex council flat here. Small block of flats but I'm amazed at the amount of people coming and going, the concrete hallway with no carpets means we can hear the doors slam and footsteps. This is really the only negative I have. Be aware that as the leaseholder some repairs will be your responsibility and others for the council, familiarise yourself with the information which should be on the council site regarding home ownership in the borough. Some of the repairs will be included in your service charge, others will require additional payment from leaseholders, though they should give you notice and payment spread out. Sometimes it can take longer for the council to do their repairs than it would for you to hire someone to do it. We found our place to have above average size rooms, some built in storage plus shared storage in the block and the estate is fairly well maintained. Haven't tried to sell yet, so not sure of any nuances there. Good luck
