In London that’s not necessarily crazy. In 2020 it might have been a cheap sale for lots of reasons. Walthamstow and surrounding has boomed even since then. We bought a house for 490, it had a collapsed roof (not pictured), original Edwardian electrics, central heating in only a few rooms with a condemned boiler. It was a probate sale so was empty for over a year so stunk, had damp and families of foxes in the garden. The carpets were soaked in dog urine.
We spent £40k on initial work - completely new roof, rebuilding ceilings upstairs, electrics, heating, plastering, basic 3 unit kitchen, bathroom and flooring in most rooms. Then we built a >100k extension. Then we spent £££££ on renovating original windows and stained glass door. And another pile of money on gardens.
We’ve been valued at 1m and listed at OIEO 975K. I expect lots of people think it’s very overpriced if they don’t know the area. 490 was insanely cheap but reflected that it was basically uninhabitable. If you wanted to do our extension this year it would cost £200k at least so that is a value factor too.
The area has then jumped massively with Walthamstow gentrification, and 3 doors down, same house finished with a loft and extension sold for 1.1m. It seems insane but prob only slightly overpriced given the beautiful Edwardian houses on a quiet lovely road.
