I think it’s a matter of waiting for the ‘right buyer’.
It looks v well kept and in good nick but some of the things that are not to my taste or preference for function (shiny black kitchen tiles etc) would be a big job and expensive to change. But someone out there will love it.
Also, for me, the extension hasn’t really been done in the best way: A long reception room 7’ wide. A full downstairs bathroom.
But it’s all about preference and individual use.
Close to Eltham Palace and The Red House and the Green Chain walk!
Good luck OP.
