Good morning.
I've been reading the forum, and whilst I find the general discussion of property prices interesting, really can't have you dissing my hood to this extent. :-)
Clapton is doing well for the following reasons:
11 minute rail link to Liverpool St. Huge Victorian properties, many intact with original features, many with large gardens.
Walking distance from Dalston and Stokey; easy distance from Islington and Shoreditch; not too far from West End. Good range of buses. (Admittedly I get a lot of cabs as the buses are slow, which is the main downside for me, but then living here, I can afford to.)
Springfield Park and Marina - beautiful and peaceful, bordering on a nature reserve. Lea Valley park. Stables and ice rink. Great library.
As for crime, if you tense up when you see a hoodie, or generally feel vulnerable, it's not for you. I popped out to the cashpoint at 1am this morning and then got wine and milk from a 24 hr shop; I wouldn't walk teeter home drunk in high heels, with an expensive handbag, I'd get a cab, but that's the same everywhere. If you take reasonable precautions you'll be left alone, and the yoot generally only bother one another. In the Hassidic streets, you're probably safer than most places. When I moved in 10 years ago, getting the last train from Liverpool St. felt a bit scary. Now, it's packed, with lots of people getting off at Clapton and happily walking home.
It's still shabby and rundown on the main drag, but it's far from a hellhole. Trendiness continues to spread outward and it's the next area predicted to take off - if I had investment money I'd open a posh coffee shop here, right now. Seriously. There's a gastro pub and an art cinema opening by the roundabout in the next couple of months. Chatsworth Road is getting chi chi.
Sorry, had to put the record straight as I see it - people buying here aren't complete mugs, they want easy City access, good property, convenient amenities and green space. Carry on!
