Well don’t forget I paid 50K for it, not 17K. So with carrying costs over 12 years, the extra 20K didn’t come close to even paying interest on my original investment. I also spent significant money on upkeep, rates (equivalent of property tax), repairs. I didn’t sell it purely because I pretty much couldn’t. But it affected my ability to buy elsewhere as I already had a mortgage. All in all I remember it as an ongoing nightmare.
Today – hard to estimate, probably 150-200K pounds. Which is completely ridiculous for a crapy 900 sq. ft. one bedroom appartment in a poor part of London. It’ll crash again.
