Not quite BTC (depends on your definition) but in the Nightingale Triangle, very close to Nightingale Lane though.
My neighbour on my road just put a 5.5 bedroom property on the market at the end of September - over 200sqm - £1.6m - and I saw within 2 weeks its gone SSTC!
Also it looks like lots of 4/5 bedroom properties, in the £1.2m to £1.5m range, seem to go quickly on Rightmove after listing. The ones that are struggling at the smaller ones, £1m-£1.2m that are 3 to 3.5ish bedrooms, or the super expensive ones humongous houses £1.8m+ that are taking time to sell.
There are house price stats but only aggregated on a postcode (e.g. SW11, SW12) level, so difficult to say whether things are going up or down. And I suspect the property type will make a difference too - probably 3/4 bedroom "flats" for sharers, likely doing poorly. But 3-4 bedroom houses, with a good size garden and a room for working from home, maybe an office shed in the garden, must be flying off the shelves.
