What is advertised to let in Overstone Court right now, what it is being asked at, how long it has been sitting, and how that compares with the blocks around it.
What the adverts name. All three adverts name the building.
Asking rents as advertised on 7 September. These are what landlords are asking, not what tenants have agreed to pay. "Where they cluster" is the middle half of the asking rents for that bedroom count — a quarter of the adverts sit above it and a quarter below.
| Type | Advertised | Asking range (pcm) | Where they cluster | Cut & still advertised |
|---|---|---|---|---|
| 2-bed | 3 | £1,025–£1,250 | — | 1 |
1 of the 3 adverts have cut their asking rent at least once and are still advertised. The cluster is shown from four adverts; a single figure means every advert of that type is asked at the same rent.
The oldest is a two-bedroom at £1,100, advertised since 4 June 2026 — 13 weeks, cut once.
Nothing from Overstone Court stopped being advertised in the seven days to 7 September. Across CF10 and CF11, 19 flats did; the median had been advertised 5 weeks.
Flats advertised, and how many of them had been advertised six weeks or more, on each Monday count. One point is added a week; the series starts with the 7 September 2026 count.
Counts before 7 September 2026 were made on a narrower basis and are not shown; the register that produces this page was completed on 6 September 2026, so this is the first comparable point.
Written by a director from the figures above, not generated. A count, not a forecast.
Counted across every advert in this count. Two agents, three flats.
When several agents advertise in one block at once, each is pricing without seeing the others' results, which is usually why the same specification is asked at very different rents in the same week. We name blocks, never flats, and we don't publish which agent holds which flat.
The same count, the same day, for the nearest blocks we track. The full list is on the block reports index.

Whole flats advertised to let on Monday 7 September 2026, from our own register of every CF10 and CF11 advert on the main portals. Asking rents, not achieved rents. Build-to-rent blocks, rooms, student houses and serviced flats are excluded. "6+ weeks" counts adverts live six weeks or more by the earliest date any portal or previous count has shown. Street rows count every advert on the street; building rows count only adverts naming the building. Fewer than 3 adverts and no figures are shown.
If it is empty, or coming empty, ask us whether it's you or the building. One email back from a director: the same count at building level, the adverts we left out named, and a straight read of what it means for yours. Free, no obligation. Pick already own it on the form.
Ask about my flatHow many flats in that building are empty right now, what they're advertised at and how long they've been sitting — the numbers the particulars leave out. Put the lot number in if it's an auction.

Where the figures come from. Every Monday we read every advert for a whole flat to let in CF10 and CF11 on the main portals and record it in our own register: the block, the bedroom count, the asking rent, whether it has been reduced, and the earliest date it appeared. The register is checked daily, so an advert that is re-posted does not reset its clock. On 7 September it held 259 live adverts (149 in CF10, 110 in CF11). Adverts that appear only on OpenRent carry a minimum age, because that site does not date them.
Counted at the level the advert names. An advert may name a building, name a different building on the same street, or name none. A building figure counts only adverts naming that building; everything else is a street figure, and the two are never mixed. Where a page is for a street, the count of adverts naming the building is shown separately.
Asking rents, not achieved rents. Every rent on this page is what was advertised. "Where they cluster" is the middle half of the asking rents for a bedroom count, shown from four adverts. Flats that disappear from the portals are recorded as gone, with the last asking rent and how long they were advertised; we say when we can't tell whether a flat let or was withdrawn.
Blocks, never flats. Nothing here identifies an individual flat, its landlord or its agent, and a block with fewer than 3 adverts shows no figures. Build-to-rent blocks, rooms, student houses and serviced apartments are left out, because none of them is an individually-owned flat.
Our figures, not the portals' content. The count is our own work, made by reading. We reproduce no listing, photograph or text from any portal and link to none of it.
Corrections in public. If you think a figure is wrong, email hello@cardiffmodernliving.co.uk and we will correct it here, with a date.
