Pimster,
I can see Hbos at 1200 by the end of the week.
Admittedly I do have a shedload so am biased but I wouldn't arbitrage out of them just yet, nothing else strikes me as a safer bet at present.
As for the buy to let speculators supporting the market, maybe in Taffees plush apartment block. Certainly not up here in Yorkshire, real people can still afford houses and at £150 a square foot not a bedsit. If the market is going to fall out of any type of housing it will be flats/apartments where you can't swing a cat, but with another 30,000 city jobs this year it may well be another 12 months before that happens.
