Buyer demand improving while rent expectations jump 11 points in a single month. That is not two unrelated data points. That is a buying environment for income investors who have their finance in place.
What Has Happened?
The RICS UK Residential Market Survey published on 10 September covers August 2026 data. Two datasets sit side by side in the report and they are pointing in opposite directions.
On the lettings side: tenant demand returned a net balance of positive 18%. Landlord instructions came in at negative 14%. That is the eighth consecutive quarter where landlord instructions have been negative, meaning fewer properties are entering the rental market than leaving it. Three-month rent expectations rose to 44% from 33% in July. Twelve-month rent expectations are running at approximately 3%. The RICS is not calling a rental market crisis, it is reflecting data that shows supply and demand moving further apart, not closer together.
On the sales side: buyer demand improved after the summer lull. Agreed sales picked up. RICS surveyors described the market as stabilising, with the slowdown that characterised the first half of 2026 showing signs of levelling off. This is not a recovery. It is a floor finding. Transaction volumes remain below the five-year average. Prices have drifted mildly negative in the most recent monthly data from Nationwide and Halifax. But the direction of buyer activity has shifted from declining to tentatively improving.
Those two readings are not contradictory. They reflect what happens when a soft purchase market meets a persistently supply-constrained rental market. Sellers who need to move are not holding out for peak prices. Buyers who want a deal can find motivated counterparties. Renters who have nowhere else to go are absorbing rent increases that landlords, facing rising compliance costs and higher finance rates, need to charge. All four of those conditions are present in the September 2026 market.
RICS data has been tracking falling landlord instructions since before the Renters' Rights Act came into force on 1 May 2026. The abolition of Section 21 and the new Ground 1A restrictions on reletting after possession have not reversed that trend. If anything, the regulatory complexity landed in May has added another category of landlord deciding the risk-adjusted case for holding residential letting stock no longer works. That judgement is most acute among smaller, personally-held portfolios, exactly the profile that has been exiting most consistently since 2023.
Why This Matters to UK Property Investors
The combination of a stabilising sales market and accelerating rent expectations is one I find genuinely useful to pay attention to. It is not the same as an outright buyers' market. It is also not the same as the 2021 situation where sellers had all the leverage and buyers were competing for stock. It sits in a specific middle position: vendors are negotiating where a year ago they were not, and renters are absorbing increases where two years ago they were pushing back hard.
For a BTL investor running income calculations, the 44% rent expectation reading matters more than the specific percentage itself. In isolation, 44% of RICS respondents expecting rents to rise in the next three months is consistent with what the past two years of supply squeeze have produced. What makes the September 2026 reading notable is the jump from 33% in July to 44% in August. That size of move in one month suggests expectations are accelerating rather than plateauing. Investors planning forward rent assumptions for properties bought in Q3 2026 should be including a 3% to 5% rental growth assumption for 2027, which is what 12-month RICS expectations support.
The negative landlord instructions reading is a direct consequence of the supply side story. Negative 14% means more landlords are withdrawing properties from the rental market than are adding them. That is an eighth consecutive negative quarter. A trend of that duration and consistency is structural, not cyclical. It does not reverse when interest rates fall slightly or when the autumn Budget passes without a CGT shock. It reverses when the regulatory and tax environment makes holding a rental property genuinely attractive for a wide range of landlord profiles again. That is not September 2026.
Practically, negative landlord instructions mean fewer properties competing for tenants in most UK markets. Where supply is genuinely constrained, landlords hold pricing power. In Birmingham B6 and B12, in Sunderland SR1 and SR4, in Leeds LS11, and in most of Manchester's M14 and M15 postcodes, void periods in 2026 have been consistently below historical averages. That is what rental supply pressure looks like from the inside of a portfolio.
The Risks Investors Need to Understand
Rent expectations rising and supply falling does not automatically make every BTL acquisition viable. The income case has to work at current finance rates, and for investors buying in September 2026, current specialist BTL rates run from around 3.40% at Paragon on qualifying properties at 65% LTV through to 4.22% on five-year fixes from The Mortgage Works. Mainstream lenders are sitting above 5.6% on two-year products. Any income calculation needs to use the rate the investor can actually access, not a best-case specialist rate if the property or portfolio profile does not qualify for it.
There is a specific risk in the August RICS data that gets less attention than the headline rent expectation figure. Tenant demand at positive 18% is lower than it has been at various points in 2024 and early 2025. The improvement in buyer demand tells part of that story: some tenants who have been renting since buying became unaffordable are now entering the sales market as conditions soften. That reduces the upward pressure on tenant demand slightly. It does not eliminate the supply-demand imbalance, but it is a nuance worth noting when modelling forward tenant demand in yield markets that have been very tight.
September 2026 also sits six weeks before the October 28 Autumn Budget, which is creating uncertainty across the whole property market. The Budget could include CGT changes that alter the disposal economics for existing landlords, which would affect the supply of tenanted stock coming to market via landlord exits. It could include further SDLT adjustments. Nobody knows. The uncertainty is suppressing discretionary purchasing across all buyer types, including BTL investors. That creates a tactical question: buy before the Budget into the current soft-price environment, or wait for clarity that may not remove the uncertainty anyway.
I would add one more risk that the RICS survey does not directly address: affordability constraints on tenants. Rental growth of 3% to 5% per year is sustainable in markets where wage growth is tracking similarly. In markets where local wage growth is below rental inflation, tenant affordability erodes, default risk rises, and void periods lengthen. In Yorkshire, the North East, and Birmingham, local wage growth has been broadly keeping pace with rental growth in 2026. In London and parts of the South East, the gap between rent levels and wages is a longer-term structural concern. The representative salary to afford average London rents is now over £74,000, which is not a sustainable tenant affordability base for the majority of the renter population.
Where the Opportunity Could Be
The setup I am watching most closely is tenanted stock from motivated sellers in yield markets where the income case already stacks without capital appreciation. The sales market stabilising after a soft period means those sellers are present. The supply crunch in rentals means the properties they are selling come with tenants already paying close to or at market rent, which removes the void and re-let cost at entry.
Birmingham B6 and B12 are producing gross yields of 6.8% to 8% on terraced residential stock at September 2026 prices. At 65% LTV and a Paragon specialist rate, the income margin before management fees and void is genuinely positive. That math works before you factor in any rental growth. If rental growth of 3% comes through in 2027, as RICS 12-month expectations suggest, the income case strengthens further in year two.
Sunderland SR1 and SR4 are consistently in the 7.5% to 9% gross yield range. Newcastle NE4 and NE6 are running 6.5% to 8% depending on property type. These markets have seen elevated tenant demand in 2026 because housing benefit tenants and lower-income workers have been priced further out of Durham and Newcastle city centre as rents rose faster than LHA rates. That demand pressure in the £550 to £750 per month rent band in Sunderland and surrounding areas is real and showing up in RICS data in the North East consistently.
Leeds LS11 and LS9 are producing gross yields of 7% to 9% on standard terraced stock. Sheffield S3 and S9 are in a similar gross yield range, typically 6.5% to 8.5%. In all of these markets, the eight-quarter landlord supply crunch RICS is recording has been visible in lower average void periods and a faster pace of re-letting when properties do come up. Limited company acquisitions of tenanted stock from exiting smaller landlords are happening quietly and regularly in all these markets. Professional investors are buying the supply that the RICS data is tracking as leaving the rental sector.
One angle I find underplayed in most commentary: limited company acquisitions by experienced landlords who understand their post-April 2027 tax position. The Lendlord Q3 2026 data showing 45.1% of BTL properties now in companies tells one story. What it does not capture is the proportion of active acquirers who are specifically buying into the current soft-price, high-yield environment because they have modelled their 2027 and 2028 tax liability in the company wrapper and the case is clear. Those investors are buying while smaller and personally-held landlords are selling. The RICS supply data confirms that picture.
Arsh's Investor View
The 44% rent expectations reading from RICS is the number that stood out to me most in this survey. Not because 44% is a record. It is not. But because in July 2026, the same survey was at 33%, and a swing of 11 percentage points in one month is unusual. It says expectations shifted sharply in August, which points to something more than gradual drift. I think what happened is that landlords and agents who had been cautiously optimistic about rental supply improving after the summer have updated that view. Supply is not improving. Demand is not softening. The numbers they are seeing in their own books are consistent with further rental growth, not a levelling off.
The sales market stabilising is real but limited. I would not call it a recovery. I would call it a pause in the decline. Buyer demand improving from a trough is not the same as buyers returning with confidence. What it means practically is that motivated sellers are still there, but they are no longer the only sellers. That is a marginally less favourable negotiating position for buyers than we had in July, but still more favourable than the 2021 to 2022 period when sellers held most of the cards.
My read on the October 28 Budget situation: the uncertainty is creating a paralysis among investors who are waiting for clarity before committing. I understand the logic but I think it is wrong. The confirmed changes are already in statute. The April 2027 property income surcharge is real and I am modelling around it. Whatever additional CGT or SDLT change might come from October 28 is unknown, and no decision made in September 2026 can fully account for it. Waiting for October 28 to tell you whether to buy in September is using the wrong variable as a decision gate. The income case on well-chosen Northern and Midlands stock at current prices either works or it does not. That calculation should drive the decision, not a speculative Budget outcome.

Key Takeaways
- The RICS August 2026 UK Residential Market Survey, published 10 September, showed three-month rent expectations at 44%, up from 33% in July. That is an 11-percentage-point jump in a single month. Twelve-month rent expectations are running at approximately 3% on average across the UK. Tenant demand came in at a net balance of positive 18%, while landlord instructions returned negative 14%, continuing the trend now in its eighth consecutive negative quarter.
- Landlord instructions have been negative for eight straight quarters, meaning fewer properties are entering the rental market than leaving it. This is structural, not seasonal. The Renters' Rights Act in force since 1 May 2026, combined with Section 24 mortgage interest restriction, higher compliance costs, and the April 2027 property income surcharge already in statute, are sustaining the exit pressure on personally-held landlords with thinner income margins.
- The sales market is stabilising. Buyer demand and agreed sales both improved in August 2026 after the summer lull. RICS described the market as finding a floor after the slowdown of earlier in 2026. Prices remain slightly negative on a monthly basis. Transaction volumes are below the five-year average. This is not a recovery; it is the beginning of a stabilisation that makes the purchasing environment moderately more accessible to buyers with finance and conviction.
- The split between a stabilising sales market and an intensifying rental squeeze is the core investor signal from this survey. Purchasing conditions have softened from the seller-dominated market of 2021 to 2022. Rental demand is hardening as supply stays constrained. An investor entering a high-yield market in September 2026 with specialist finance in place benefits from both conditions simultaneously.
- Income-first markets remain the clearest opportunity. Birmingham B6 and B12 (6.8% to 8% gross), Sunderland SR1 and SR4 (7.5% to 9%), Leeds LS11 and LS9 (7% to 9%), and Sheffield S3 and S9 (6.5% to 8.5%) all produce income margins that work at 65% LTV specialist BTL rates from around 3.40%. In all of those markets, the RICS landlord supply crunch is visible in below-average void periods.
- The October 28 Autumn Budget is creating uncertainty across the market. Some investors are waiting for clarity before committing. The confirmed April 2027 property income surcharge (22% basic, 42% higher, 47% additional rate) is already in statute. Speculative Budget changes to CGT or SDLT are unknown. An acquisition decision in September 2026 should be driven by whether the income case stacks at current prices and rates, not by a speculative Budget outcome that may not remove the uncertainty even if it confirms a specific measure.
Frequently Asked Questions
What did the RICS August 2026 UK Residential Market Survey show about rents?
The RICS August 2026 UK Residential Market Survey, published on 10 September 2026, showed three-month rent expectations at 44%, up sharply from 33% in July. Respondents expect UK rents to rise by approximately 3% over the next 12 months. In the lettings market, tenant demand returned a positive 18% net balance while landlord instructions came in at negative 14%, continuing the eighth consecutive quarter of falling supply entering the rental market. RICS described the imbalance between demand and supply as putting sustained upward pressure on rents.
Why are landlord instructions to letting agents still falling in 2026?
Landlord instructions have been negative for eight consecutive quarters in the RICS survey, meaning more landlords are withdrawing properties from the rental market than are adding them. The drivers are cumulative: the Renters' Rights Act in force since 1 May 2026 abolished Section 21 and introduced new Ground 1A restrictions, adding possession risk and compliance complexity. Section 24 mortgage interest restriction has been fully in force since April 2020, reducing net income for higher-rate personal taxpayers. The April 2027 property income surcharge, already in statute, adds 2% above standard Income Tax rates to rental income from April 2027. Rising compliance costs from EICR, Gas Safety, EPC, and now PRS Database registration fees compound the pressure. Landlords with thin income margins, typically smaller personally-held portfolios, are exiting before those pressures fully land.
Is the UK housing sales market recovering in September 2026?
RICS described the August 2026 data as the market stabilising, not recovering. Buyer demand and agreed sales improved after the summer lull, which moved the reading away from the declining trajectory seen in the first half of 2026. Monthly price data from Nationwide and Halifax remains slightly negative. Transaction volumes are below the five-year average. The October 28 Autumn Budget is suppressing discretionary purchasing across buyer types. The more accurate description is a floor finding rather than a recovery: the pace of deterioration has stopped, but the conditions for a meaningful sustained recovery, affordability improving, mortgage rates falling meaningfully, Budget uncertainty resolved, are not all in place simultaneously in September 2026.
Which UK regions are seeing the strongest rental demand in 2026?
The RICS data points to national rental demand at positive 18% in August 2026, but regional variation is significant. The North East, Yorkshire, the Midlands, and the North West have seen consistently elevated tenant demand throughout 2026, with below-average void periods reported by landlords operating in Sunderland, Newcastle, Leeds, Sheffield, Birmingham, Nottingham, and Manchester. London and the South East continue to show strong demand but at rent levels that are reaching affordability limits for many tenant groups, with a representative salary of over £74,000 now required to afford average London rents. Northern and Midlands markets are seeing a more sustainable demand profile where rental growth is tracking wage growth more closely.
Should I buy a buy-to-let property before or after the October 2026 Budget?
There is no definitive answer because the Budget outcome is unknown. The argument for buying before October 28 is that the current soft-price environment, motivated vendors, and available specialist finance products may not persist after the Budget, particularly if positive Budget news brings buyers back in volume. The argument for waiting is that a CGT or SDLT change could affect the disposal or acquisition economics in a specific way. The income case on a well-chosen Northern or Midlands property at 7% to 9% gross yield with 65% LTV specialist finance either stacks now or it does not. The April 2027 property income surcharge is confirmed in statute regardless of the Budget. Basing an acquisition decision primarily on speculative Budget outcomes, rather than confirmed current income calculations, is the weaker approach.
