How much is my house worth in UB3?

Across 804 sales registered with HM Land Registry in UB3, the median price paid is £421,800 — by type: flats & maisonettes £300,000, semi-detached houses £525,000, terraced houses £470,000. Half of all sales sit between £300,000 and £520,000; 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 UB3?

The Land Registry does not record time on market, so treat any precise figure with caution. 370 sales were registered in UB3 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 UB3?

London agents typically charge between 1% and 2% plus VAT on a sole agency basis. On the UB3 median of £421,800, that is roughly £4,200 to £8,400 plus VAT. Multi-agency fees are higher; ask what is included before comparing.

Do I need a valuation before selling?

Yes. In UB3 the middle half of registered sales spans £300,000 to £520,000, 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 UB3 ranging from £183,000 to £715,000 across most sales, the error can easily run to tens of thousands of pounds. Use one as a starting point, not a price.
