Knight Frank has cut its UK house price growth forecast for 2026 to 1.5 percent, but says rents will keep rising as tighter possession rules and weak sales confidence keep pressure on the private rented sector.
That split matters for landlords. Softer house price growth is not automatically bad news if rental income holds up, but it does change the balance of where returns come from. Investors relying on capital appreciation look set for a slower year. Investors focused on yield and cashflow may fare better, provided they can handle higher regulation and financing costs.
Rental growth is expected to outpace sales values
Knight Frank said rental growth is still expected to reach 4 percent in 2026 and 3.5 percent in 2027, even after trimming its forecasts slightly. The agency tied that resilience to the disruption now hitting the sales market and to the extra caution likely to come with the Renters’ Rights Act.
The warning for landlords is that firm rents do not mean an easy market. If tenant demand stays strong because more would-be buyers delay moves, landlords may still face heavier regulation, stricter compliance and a slower path to recovering possession when things go wrong.
This follows Landlord Knowledge’s recent report on rent growth easing while house prices edged higher. Knight Frank’s latest forecast points to a similar conclusion from a different angle: rental income may remain more dependable than sales growth, but the sector is offering fewer easy wins.
Yield looks more important than capital growth again
There is a useful reality check in Knight Frank’s downgrade. For much of the past cycle, landlords could tolerate thin margins because asset prices were doing part of the work. A 1.5 percent house price forecast changes that maths. Returns will depend more heavily on financing discipline, local demand and how much spending a property needs over the next few years.
That is why this forecast sits naturally alongside Landlord Knowledge’s latest coverage of landlord exit rates. If price growth stays muted while compliance risk rises, some owners may still choose to sell even if rents remain firm. Others may see better opportunity in well-bought stock outside the most expensive markets.
The bigger point is that landlords should not confuse stable rents with stable policy risk. Knight Frank’s outlook helps explain why the rental market may stay tight even if the sales market loses momentum.

What this means for landlords
- If you’re buying for yield: slower house price growth puts more emphasis on financing, void assumptions and local rent depth.
- If you’re planning a sale: muted price growth may argue for sharper pricing rather than waiting for a strong bounce.
- Watch for: regional markets where rental demand stays high but sales activity softens.
- Bottom line: in 2026, income may matter more than paper gains.
Editor’s view
Landlords have seen this pattern before. When price growth cools, the market gets more honest. The winners are usually not the boldest buyers, but the ones who know exactly where their return is coming from.
