The UK residential market enters September with subdued price growth, resilient rental demand and an increasingly important question around future housing supply.

Buyer activity remains constrained by higher mortgage costs, while greater stock availability has given purchasers more choice and, in some cases, more negotiating power. For investors, that creates a market where entry price and asset selection matter more than short-term price momentum.

Nationwide reported annual UK house price growth of 1.6% in August, while Savills noted that higher mortgage rates continue to weigh on affordability and transaction activity. The market is not weak across the board, but it remains highly price-sensitive.

Rental demand remains a key support

The rental market continues to provide a stronger backdrop. Average UK private rents were 3.7% higher year-on-year in July, according to the ONS, although performance varies significantly by location and property type.

For investors, headline rental growth is only part of the picture. The more important question is whether an individual development has sustainable demand, limited competing stock and a tenant profile capable of supporting the projected rents over the long term.

The new homes pipeline is tightening

The most significant issue for the new homes market may be what is happening further up the development pipeline.

Around 232,000 residential units secured planning permission in 2025, 15% fewer than the previous year, while approvals remained under pressure into 2026. This matters because the homes not progressing through planning today are the completions that may be missing from the market several years from now.

Government reforms may help improve housing delivery, but the effect will not be immediate. Land still needs to be acquired, planning secured, development finance agreed and construction completed. Even schemes with permission may not proceed if viability, funding or sales conditions do not support delivery.

The result is a significant lag between policy intervention and completed housing supply.

For investors, this means national housebuilding targets are less relevant than the pipeline in the specific market being considered. What matters is how much competing stock is realistically likely to be delivered over the next three to five years.

Where constrained new supply coincides with strong employment, population growth and rental demand, the investment case can become materially stronger.

Financing remains the main constraint

Mortgage costs remain the key headwind. Higher borrowing rates have reduced affordability and changed the return profile for leveraged investors.

That makes it increasingly important to assess investments on realistic assumptions. A property that only works if mortgage rates fall sharply or rents rise aggressively is unlikely to offer a sufficiently robust investment case.

Purchase price, financing costs, service charges, rental demand and future resale liquidity all need to be considered together.

The McCooke view

The market is currently presenting two contrasting signals. Financing conditions remain challenging and short-term price growth is modest, but rental demand remains supportive and the future supply of new homes is becoming increasingly constrained.

That supply dynamic deserves particular attention.

Even if government policy succeeds in accelerating housebuilding, it will take several years for additional stock to reach the market. The weaker planning and development environment of recent years may therefore already be shaping the supply conditions investors will face later in the decade.

This does not make every new home a good investment. It does, however, increase the importance of identifying developments where future supply is limited, demand is sustainable and the entry price remains attractive.

For investors, that is likely to be far more relevant than trying to predict where house prices will be six months from now.
