How much is my house worth in NW3?

Across 993 sales registered with HM Land Registry in NW3, the median price paid is £930,000 — by type: flats & maisonettes £822,099, terraced houses £2.19m, semi-detached houses £3.98m. Half of all sales sit between £620,000 and £1.75m; where yours falls depends on size, condition, lease and the exact street, which is what a valuation pins down.

How long does it take to sell a house in NW3?

The Land Registry does not record time on market, so treat any precise figure with caution. 500 sales were registered in NW3 in the latest twelve months of data, and in our experience a well-priced London home takes around ten to sixteen weeks from launch to completion, most of it conveyancing.

What are estate agent fees in NW3?

London agents typically charge between 1% and 2% plus VAT on a sole agency basis. On the NW3 median of £930,000, that is roughly £9,300 to £18,600 plus VAT. Multi-agency fees are higher; ask what is included before comparing.

Do I need a valuation before selling?

Yes. In NW3 the middle half of registered sales spans £620,000 to £1.75m, so an area median alone tells you little about your own home. A valuation sets the asking price, the strategy and the timing — and it is free.

How accurate are online valuations?

An online estimate works from averages and cannot see condition, light, lease length or outside space. With prices in NW3 ranging from £350,000 to £4.71m across most sales, the error can easily run to tens of thousands of pounds. Use one as a starting point, not a price.
