It's a real tough situation for those with lira and ultimately needing to change to pounds. I used to think I set the sterling/lira exchange rate - if I needed lira the rate would plummet in the days before my transaction, if I needed to change lira to pounds the rate would soar just before.
We brought our money home at a rate which was devastatingly bad, yet with hindsight we are so glad we did. The rate is far worse now. I suppose it's easy to tell people to bite the bullet and get out, because I do believe that. But I know only to well how hard a decision that is to make.
