Eleven area searches across south London, plus one sold-price check on the Hove block. The brief never changed: two bedrooms, private outdoor space, a long lease, and period character where it exists. All listings checked 15 August 2026.
It started with a one-bedroom flat in Forest Hill — £375,000, 605 sq ft, private garden, 114-year lease, £620 per square foot. Everything that follows is an attempt to find a two-bedroom version of it without paying much more.
The answer turned out to be geographic and completely monotonic. Every step towards a better-connected, more established address costs roughly £150 per square foot. South Norwood is the cheap end at £383/sq ft; Herne Hill is the expensive end at £831. Same brief, same must-haves, and £500,000 in Herne Hill buys 667 square feet where £400,000 in South Norwood buys 1,045.
There is no undiscovered pocket left. Eleven searches in, the map is complete — what remains is a preference question, not a search question.
The original brief, with the budget still open.
Forest Hill & around, up to £650k
11 flatsForest Hill · Honor Oak · Sydenham · Brockley · Crofton Park
Two-beds in the mould of the Forest Hill one-bed, with the ceiling set high enough that nothing has to be compromised. Farren Road tops it at £650,000 for 1,109 sq ft — almost double the space for £275,000 more, with a 74 ft garden, share of freehold and the fullest period spec on any list. Duncombe Hill is the value pick: £99 a year service charge against £1,740 on the flat that started this.

104 salesDyke Road, Hove BN3 6NF · HM Land Registry price paid data
Every recorded sale in the block since 1995, and what the last three years say the flat is worth now. The going rate is £265,000 — the median of eight sales since September 2023, seven of which landed in a tight £250k–£275.5k band. Flat 32 sold twice in that window, £266,000 then £265,000: the cleanest evidence that the block has gone sideways, not up.

The Norwoods at £400k
7 flatsSouth Norwood SE25 · Crystal Palace & Upper Norwood SE19 · West Norwood SE27
The strongest search of the eleven, and it isn't close. South Norwood is where the brief actually gets met without a trade: ground-floor period conversions with share of freehold, private gardens and real square footage at £375k–£400k. Woodside Green is 1,045 sq ft with a 60 ft garden at £400,000. The catch is the postcode — it's further out and it's Croydon, which is exactly why it's cheap.
Open the list →Forest Hill & around at £400k
12 flatsForest Hill · Honor Oak · Sydenham · Brockley · Crofton Park
What £400,000 buys in the original patch, and how little of the £650k list's quality actually had to be surrendered. Includes the Brownhill Road size comparison — the clearest illustration on the site of what you pay per square foot as you move north and west — plus a "worth a look further out" section that pointed the way to every search that followed.
Open the list →Hilly Fields & Peckham at £400k
8 flatsHilly Fields · Ladywell · Brockley · Peckham · Nunhead
The two areas from the original notes, priced side by side. Ladywell and Brockley hold up on space; Peckham and Nunhead charge £600 to £724 per square foot, which at a £400,000 ceiling means 518 to 667 sq ft. St Mary's Road is the pick of the Peckham entries — 32 ft garden plus a balcony, 125-year lease — but you are buying the postcode, and the page says so.
Open the list →West Norwood SE27 at £400k
5 flatsSE27 proper, with the West Dulwich SE21 edge
SE27 on its own, examined properly rather than as a footnote to the Norwoods list. Not much comes up here, but what does is decent — Auckland Hill gives you 725 sq ft, a 46 ft private garden and a 148-year lease at exactly £400,000. This is the page that made the £425k and £500k follow-ups worth running.
Open the list →Sydenham SE26 at £400k
5 flatsSydenham · Penge East · one Overground stop from Forest Hill
Better value at £400k than the same area offers at £500k, which is not how this normally works. The sub-£400k stock includes two genuinely large flats — 936 and 790 sq ft — that the upper band simply doesn't have. Collingtree Road at £401/sq ft is the second-cheapest figure anywhere on the site. The trade here is condition and lease rather than space, and all of it is visible in the listings.
Open the list →Streatham Hill at £400k
5 flatsSW2 & SW16, including the Tulse Hill and Brixton Hill edges
Lots of flats, one significant hole: private outdoor space barely exists here at this price. The best candidate, Palace Road, is £400,000 for 617 sq ft with a shared garden — so it fails the brief on the one point that started the whole search. Useful mainly as the page that ruled an area out, which is worth as much as one that rules an area in.

West Norwood at £425k
6 flatsSE27 · the £400k list plus what £25,000 more unlocks
The most productive £25,000 in the entire search. Twenty-five thousand pounds opens more genuinely new stock in SE27 than a hundred thousand did anywhere else — the page splits into what's newly in range and what carried over from £400,000, so you can see precisely what the extra buys. If any single page changes the budget decision, it's this one.
Open the list →West Norwood at £500k
6 flatsSE27 · plus what £500k buys if the two-bed rule is dropped
The extra £100,000 buys gardens, not floor area. Ullswater Road is £500,000 for 642 sq ft — £779 per square foot in an area where £400,000 was buying 725 sq ft. The page includes a genuinely interesting sidebar: a 932 sq ft three-bed at £475,000, if the two-bedroom rule turns out to be negotiable. Ends with a straight verdict on whether the stretch is worth making.
Open the list →Sydenham SE26 to £500k
6 flatsSydenham · one stop from Forest Hill
The strongest tenure position of any area on the site — share of freehold is standard in Sydenham rather than the exception, which removes the lease-length question that hangs over most of the other lists. What you pay for it is £691 to £767 per square foot, noticeably worse value than the same area's £400k band. Read this one alongside Sydenham at £400k.
Open the list →Herne Hill SE24 to £500k
4 flatsSE24, including the Brixton SW2 and Denmark Hill SE5 edges
A different market from everywhere else — roughly double South Norwood per square foot. £500,000 buys 600 to 670 sq ft, less than the one-bed that started this and £125,000 more. What you get is Brockwell Park, a real high street, Thameslink to Farringdon and the Victoria line walkable. The page carries the full sixteen-property comparison table that summarises every search on the site.

| Sydenham SE26 (£400k band) | £401–£607 | 790–936 sq ft | Space for the money, with condition or lease attached |
| Forest Hill SE23 | £430–£620 | 605–872 sq ft | The origin patch; still competitive |

| The 1-bed that started this | £620 | 605 sq ft | Forest Hill, £375,000 — the benchmark |
| Streatham Hill SW2/SW16 | £648 | 617 sq ft | Ruled out — no private gardens at this price |
| Sydenham SE26 (£500k band) | £691–£767 | ~650–720 sq ft | Share of freehold as standard |
| Herne Hill SE24 | £717–£831 | 593–667 sq ft | The premium end, knowingly paid |
Three questions, and none of them are search questions.
One — space or address. A thousand square feet and a sixty-foot garden in South Norwood, or six hundred and sixty in Herne Hill for a hundred thousand pounds more. The trade is fully mapped and it is monotonic; there is no clever third option hiding in an area nobody has looked at yet. Go and stand in both on a Saturday.
Two — the £425,000 question. West Norwood at £425,000 opens more new stock than any other budget increase tested. If the budget can move at all, that is where the twenty-five thousand goes furthest.
Three — leases. Tenure is unpublished on a striking number of the more expensive listings, particularly in Herne Hill, where three of four say "ask agent". A short lease behind a £500,000 asking price is a far bigger problem than one behind £350,000. Ask before viewing, not after.
