UK House Prices vs Rents: Why Income Is Doing the Heavy Lifting Right Now

In the short newsletter we sent out, the third point was simple:

House prices are creeping up, but rents are still doing the heavy lifting.

This longer breakdown digs into what that actually means – using the latest data – and what it implies for:

• Traditional buy-to-let landlords

• People investing through Fractional Keys

• The outlook for UK property over the next few years

1. House prices: modest growth, not a boom

Across almost every major index, the story is the same:UK house prices are rising slowly – low single-digit growth – with big regional differences.

Official HPI (Land Registry / ONS)

The UK House Price Index for September 2025 shows: 

• Average UK price: ~£272,000

• Annual change: +2.6%

• Monthly change: –0.6% (prices dipped slightly between August and September)

So over the year, prices are up – but just. There’s no runaway bull market here.

Lender indices (Halifax & Nationwide)

Lender data paints a similar picture:

• Halifax (October 2025):

  • Annual change: +1.9%

  • Monthly change: +0.6%

  • Average price: £299,862, a new record high in cash terms 

• Nationwide (October 2025):

  • Annual change: +2.4%

  • Monthly change: +0.3% 

So depending on the index, annual growth is somewhere between about 1–3%.

Regional split: North ticking up, South cooling

Aggregates hide a lot of local variation:

• Zoopla’s latest index puts the average UK price around £270,200, up 1.3% year-on-year – but with southern England seeing small declines (around –0.2%) while markets like the North West and Scotland are still growing more strongly. 

• The ONS has highlighted stronger annual house price growth in the North East (around 7–8%) versus near-flat growth in London. 

• The FT reports London prices down 1.8% year-on-year to September 2025 and more than 15% off peak in some prime boroughs, reflecting a long period of stagnation after years of outperformance. 

Big picture: prices nationally are edging higher, but this is not a 2020–21 style surge. Real (inflation-adjusted) growth is close to flat.

2. Rents: still running hotter than prices

Where prices are jogging, rents are still running, even if they’re starting to slow.

The latest ONS “Private rent and house prices” bulletin for August 2025 shows: 

• Average UK monthly private rent: £1,348

• Annual rent growth: +5.7%

  • Down from 5.9% the month before – the eighth consecutive month of slowing rental inflation, but still a high rate.

Breakdown by country (12 months to August 2025):

• England: £1,403, up 5.8%

• Wales: £811, up 7.8%

• Scotland: £1,002, up 3.5%

• Northern Ireland: £860, up 7.2% (to June 2025)

In England specifically, the ONS notes:

• Fastest rent growth in the North East (9.2%)

• Slowest in Yorkshire & The Humber (3.4%)

Other datasets tell the same story in slightly different numbers:

• Homenicom puts the average rent in England at £1,410 in September 2025 – up 5.5% year-on-year.

So even though rental inflation is slowing, it’s still running at roughly double the pace of house price growth.

That’s exactly what we mean by:

“Rents are doing the heavy lifting.”

Most of the return in today’s market comes from income, not big instant jumps in capital values.

3. What this means for yields

If rents are up around 5–6% year-on-year and prices are up around 2–3%, then – in simple terms – gross yields are nudging higher:

• Suppose last year a property was worth £250,000 and rented for £12,000 a year → 4.8% gross yield.

• If today the price is up 2.5% (~£256,250) but rent is up 5.5% (~£12,660), the gross yield moves to roughly 4.9–5.0%.

That’s obviously simplified and ignores costs, but the direction is right:

• When rents rise faster than prices, yield improves (all else equal).

• In a world where interest rates aren’t near zero anymore, that income component is increasingly what makes property stack up.

For investors, the interesting bit is this balance:

• Capital growth: modest, regionally mixed, very unlikely to rocket in the short term.

• Income: still strong, especially in high-demand rental markets where supply is tight.

4. For traditional landlords: a squeeze and an opportunity

For classic buy-to-let landlords, this environment is a mix of tailwinds and headwinds.

Tailwinds

• Rents are historically high and still rising faster than prices.

• Demand to rent remains strong because buying is harder:

  • Higher mortgage rates

  • Stricter affordability tests

  • Bigger deposits needed

That supports:

• Lower vacancy in good locations

• Resilient cashflow for well-run rentals

Headwinds

At the same time:

• Mortgage rates are well above the 2010s era.

• Running costs have risen (maintenance, insurance, service charges).

• The Autumn Budget has just announced higher tax on rental profits from 2027, and a “mansion tax” on £2m+ homes – adding to an already heavy tax and regulatory load on landlords.

So while the raw rental numbers look attractive, net yield after tax and finance can feel under pressure – especially for highly leveraged or higher-rate taxpayers.

For many landlords, the strategic question becomes:

“Is the extra yield worth the extra hassle and policy risk?”

5. For Fractional Keys investors: why “rents > prices” is interesting

From a Fractional Keys perspective, this kind of market is actually very attractive.

Our model (as you’ve shaped it):

• Focuses on rundown / value-add properties,

• Keeps total cost well below £2m per property,

• Refurbishes to a decent standard, then holds for rental income and long-term growth.

Here’s why the current environment fits that approach.

A. Income-led market = good for yield strategies

If:

• Prices are only growing at 1–3% a year, but

• Rents are growing at 5–6%,

then the main driver of returns is rental income, not quick flipping.

That lines up with what Fractional Keys is built for:

• Collecting monthly rent,

• Building steady cashflow,

• Letting capital appreciation play out over the longer cycle rather than relying on short-term spikes.

B. Mid-priced stock, strong rental demand

The biggest rental pressures are often in:

• Everyday family housing and

• Good commuter / regional city stock,

not necessarily prime £2m+ mansions.

That aligns with your plan to:

• Target properties under ~£200k total purchase + renovation,

• Put them into areas with steady renter demand,

• Offer investors exposure to “real world” housing that people actually live in.

Meanwhile, high-end segments (especially in London) are seeing price weakness and may face extra tax drag from the mansion tax – a space we don’t need to play in. 

C. Diversification vs all-in exposure

Traditional landlord:

• One or two properties, heavily geared.

• If that local market stagnates or a tenant fails, your portfolio feels it sharply.

Fractional Keys investor:

• Can spread small amounts across multiple properties and cities.

• Your exposure to any one local market or tenant is much smaller.

• You still benefit from rents outpacing prices, but with softer downside if one area underperforms.

6. What to watch next

A few key indicators will tell us whether this “rents doing the heavy lifting” trend continues:

1. Wage growth vs rent growth

   • If rents keep rising faster than wages for too long, affordability will bite and growth has to cool.

   • So far, rent inflation is slowing, but remains high by historical standards. 

2. Interest rates and mortgage costs

   • If the Bank of England cuts rates gradually from here (as many expect), mortgage rates should ease further, potentially supporting more buyer demand and slightly stronger house price growth. 

3. Tax and regulation

   • The Autumn Budget just tightened the screws further on landlords; future Budgets and regulatory changes will influence how many private landlords stay in or leave the market. 

4. New supply

   • Construction levels and planning policy will determine how quickly the market can expand rental stock. Limited supply tends to lock in higher rents.

7. Takeaways in one go

• House prices: up roughly 1–3% over the last year depending on the index – modest growth, with some weakness in London and the South versus stronger Northern and devolved-nation markets. 

• Rents: still up around 5–6% annually, though that rate is gradually slowing – meaning income, not capital gains, is doing most of the work in returns. 

• Yields: improve at the margin when rents outrun prices – especially on sensibly priced, high-demand stock.

• Landlords: benefit from strong rents but face rising costs, higher taxes and more risk sitting directly in the firing line of every policy change.

• Fractional Keys investors: can tap into the same rental tailwinds via a diversified, professionally managed portfolio of sub-£2m properties, without personally owning and managing a buy-to-let.

In a world of modest house price growth and strong but slowing rental inflation, the question isn’t “Is property still worth it?” – it’s “What’s the smartest way to get exposure?”

Fractional Keys is being built for exactly this kind of market:steady income, sensible valuations, and wide access – not just for people with six-figure deposits.
