Your goal: Find the right London borough, understand what a flat actually costs at entry level, and know whether now is a good time — before spending a penny on a solicitor.
Start Here — What Does Entry-Level Actually Look Like?
Run this first. Five boroughs, one question.
Query 1 of 10
"What is the lower quartile flat price in Lewisham, Waltham Forest, Southwark, Hackney, and Islington?"
Lower quartile = the entry price point. 25% of flats sold for less than this. It's your floor — not the median.
✓ Real data — HM Land Registry 2025
Lower Quartile Flat Price — 2025
Pick your top two based on your budget. The remaining queries focus on those.
Check the Trend — Going Up or Down?
Query 2 of 10
"Show me the 5-year flat price trend in Lewisham."
Is the market still falling from 2022, or recovering? Don't buy at the bottom of a bounce.
✓ Real data — HM Land Registry 2020–2025
Median Flat Price — Lewisham
Lewisham flats have been remarkably stable — no 2022 bubble, no sharp correction. Prices today are essentially flat vs 2020.
Is the Market Active Enough?
Query 3 of 10
"How many flats sold in Lewisham in 2025?"
Low volume = thin market. Hard to buy, hard to sell later.
✓ Real data — HM Land Registry 2025
1,691 flat transactions in Lewisham in 2025. That's an active market with plenty of choice.
How Much of It Is Actually in Your Budget?
Query 4 of 10
"What percentage of flats in Lewisham sold for under £500,000 in 2025?"
Tells you how realistic your budget is. If only 8% of flats fell under your number, the search will be brutal.
✓ Real data — HM Land Registry 2025
~80% of Lewisham flats sold for under £500,000 in 2025 — a deep, accessible market. Strong supply at that level.
Narrow to a Postcode
Query 5 of 10
"Which postcode in Lewisham had the lowest median flat price in 2025?"
Borough averages hide huge variation. One postcode can be £80,000 cheaper than another in the same borough.
✓ Real data — HM Land Registry 2025
Median Flat Price by Postcode — Lewisham 2025
Query 6 of 10
"How has the flat price in SE12 changed since 2019?"
Check whether the cheapest postcode is cheap for a reason — or just less discovered.
Avoid the New Build Trap
Query 7 of 10
"What is the new build vs resale flat price in Lewisham?"
New builds sell at a premium and often fall in value the moment you move in.
✓ Real data — HM Land Registry 2025
New Build vs Resale — Lewisham Flats 2025
£102,500 new build premium. Buy resale.
Check Your Backup Borough
Query 8 of 10
"What is the lower quartile flat price in Waltham Forest and how does it compare to Lewisham?"
Keep your options open. Sometimes £20,500 more buys a completely different neighbourhood and commute.
✓ Real data — HM Land Registry 2025
Waltham Forest LQ: £315,000 vs Lewisham: £294,500 — a £20,500 gap. Both accessible on similar budgets.
Leasehold vs Freehold
Query 9 of 10
"What is the price difference between leasehold and freehold flats in Lewisham?"
Most London flats are leasehold. Know what the freehold premium looks like before getting excited about a listing.
What's Happening Right Now?
Query 10 of 10
"What is the early 2026 flat price in SE12?"
The most recent Land Registry signal. Is the market moving before you put in an offer?
Demo: How This Leads to a Decision
Demo walkthrough — not financial advice
Budget: £320,000 · Target: A resale flat under £320k
After 10 queries, here's what the data shows:
→ Lewisham is the only borough where the lower quartile (£294,500) sits comfortably under budget. Waltham Forest is close at £315,000.
→ Within Lewisham, BR1 (£270,000 median) and SE12 (£290,000 median) are the most affordable postcodes with enough volume to give real choice.
→ Prices have been flat for 5 years — no artificial peak to fall back from. ~80% of flats sold for under £500k in 2025, confirming deep supply across the borough.
