🏠 The SDLT Surcharge Debate - Case Study 7

Tuesday 1st April 2025

Golders Green, NW11 9Headline

The Final Nail?

Post-April SDLT Hikes in NW11The final SDLT change on April 1, 2025, which reduced the nil-rate band back to £125,000 (from the temporary £250,000) and kept the 3% investor surcharge, further eroded thin margins in expensive areas.

Case Study 7: The Tax BurdenProperty: Mid-terrace requiring full renovation, Sinclair Grove (NW11 9).

Bought: April 2025: £850,000.

SDLT Bill (Investor Rate): approx. £68,000 (The tax bill now consumes over 20% of the expected gross profit before factoring in build cost).

Renovation Cost: £100,000.

Target Sale: £1,050,000.

Result: After tax and renovation, the remaining margin is just £32,000 (before finance and selling fees). This confirms the industry observation (supported by Hamptons data) that SDLT alone now makes flipping non-viable for mid-range properties in London.
