Three in five homes listed for sale since January are still without a buyer, according to the latest Zoopla housing market data, as sales agreed fell 7 percent year on year and buyer demand dropped 15 percent.
The fresh slowdown matters because it points to a thinner market just as many landlords are weighing whether to buy, hold or sell into the second half of 2026. Mortgage rates that moved up to around 5 percent in April appear to have knocked confidence again, while London and parts of the South are seeing more stock build up.
For landlords, that creates a more mixed picture than the headline slowdown suggests. Softer demand can improve buying conditions in some markets, but it also raises the risk of overpaying for stock that may take longer to resell if refinancing or exit plans change.
Mortgage costs are slowing buyer demand
Zoopla’s latest market update shows higher borrowing costs are still doing the damage. The portal said average mortgage rates rose from 4 percent at the start of the year to 5 percent in April, adding pressure to monthly costs and pushing some would-be buyers into a wait-and-see stance.
That helps explain why more homes are sticking on the market. The latest figures reported by Zoopla show that 60 percent of homes launched since January remain unsold, with the sharpest slowdown in Wales and the Midlands.
That matters to landlords because softer owner-occupier demand can open up buying opportunities, especially where sellers need to move and pricing starts to adjust. But it also means investors need to be tougher on local comparables, yields and refinance assumptions than they were earlier this year.
This follows Landlord Knowledge’s recent report on Halifax’s second monthly price dip, which highlighted how weaker house price momentum was starting to reopen a buyers’ market for some investors. The latest Zoopla figures suggest that window may be widening in higher-priced or slower-moving areas.
Regional splits are creating different landlord opportunities
The slowdown is not uniform. Zoopla’s data points to London still under heavier pressure, with annual price growth turning negative again, while northern markets continue to hold up better. That leaves landlords with a familiar but sharper divide between weaker southern resale conditions and more resilient lower-cost regions.
Investors targeting flats will also be watching closely. Landlord Knowledge recently reported on the record gap between house and flat prices, and a softer sales market is unlikely to help recovery in leasehold-heavy areas where service charges and reform uncertainty are already hitting demand.
A contrarian reading for landlords is that weaker mainstream buying demand does not automatically mean weaker rental demand. If more first-time buyers pause purchases because rates remain high, some will stay in the private rented sector for longer. That can support lettings demand even while sales volumes soften.
Still, there is a warning here for landlords planning short-hold flips or rapid exits. A market where buyers are more selective and homes sit longer can quickly erode projected gains once finance, voids and works are factored in.
Why pricing discipline matters more now
Zoopla’s own view is that correctly priced homes are still selling, while overpriced stock is sitting. That is not just a message for owner-occupier sellers. It applies to landlords buying additions, valuing existing assets and deciding whether to sell weaker units before autumn.
Anyone expanding a portfolio now needs to stress-test the deal against slower resale conditions, not just current rents. And landlords trying to dispose of stock should assume buyers have more room to negotiate than they did earlier in the year.
The underlying source remains Zoopla’s house price index coverage for the UK market, which has already flagged a market where active buyers are fewer, more price-sensitive and taking longer to commit.
What this means for landlords
- If you’re buying: Expect more room to negotiate in slower southern markets, but underwrite for slower exits and stricter yield discipline.
- Watch for: Any further jump in mortgage pricing over summer, which could leave more stock sitting and push sellers to cut harder.
- Bottom line: A weaker sales market can create buying chances for landlords, but only if the numbers still work after assuming softer resale conditions.
Editor’s view
For landlords, this is not a crash story. It is a pricing story. The investors who do best from here are likely to be the ones willing to buy selectively, walk away quickly and stop treating every softer market as a bargain.
