In January 2026, 8% of new BTL lending was agreed above 5%. By April it was 43%. That is not a gradual shift. It happened in a single quarter.
What Has Happened?
Five-year BTL fixed rates taken out in 2021 are hitting their expiry window. Bank Rate that year sat at 0.1%. Limited company five-year deals were available from around 1.5% to 2.2% from specialist lenders. A significant cohort of portfolio landlords locked in at those levels, some to sit out the rate cycle they knew was approaching, some because five years suited their portfolio refinancing plan at the time. Most of those deals expire between mid-2025 and the end of 2026.
Hamptons published their April 2026 remortgage analysis this month. Landlords refinancing from 2021 five-year products saw monthly mortgage payments rise by an average of 28.5%. Those coming off two-year deals taken in 2024 at around 4.5% faced a much smaller 3.4% increase. The two groups are living in very different mortgage markets, but both are happening now, simultaneously.
The rate environment itself moved sharply in the first four months of 2026. The average two-year fixed BTL rate sat at 4.66% on 1 March. By 1 April it had reached 5.44%. The average five-year fixed moved from 5.05% to 5.75% in the same period. Moneyfacts confirmed in late March that BTL mortgage costs were at their highest for two years. In April 2026, 43% of all new BTL applications were agreed at rates above 5%, according to Hamptons. In January the same figure was 8%.
The driver was swap rates. The Iran conflict from February pushed energy prices and inflation expectations higher. Swap rates track those expectations closely and fixed BTL products follow swap rates within days. Two-year swaps currently sit at 3.49%, down from a peak during March and April but still well above the 2.49% seen in late 2024. Some lenders including Nationwide, HSBC, Halifax and Santander started cutting rates in May as swap rates pulled back slightly, but the products on offer in late May are meaningfully more expensive than they were at the start of the year.
The Bank of England held Bank Rate at 3.75% at the April 29 MPC meeting, 8 votes to 1. The single dissenter voted to raise to 4%, not to cut. The next decision is June 18. JP Morgan is forecasting a rate rise at that meeting. Market pricing in late May expects a hold. Lombard Odier has published a forecast of base rate reaching 2.75% by Q4 2026 through a series of cuts. Three credible institutions, three positions pointing in opposite directions from the same decision date.
Why This Matters to UK Property Investors
The 28.5% payment shock for the 2021 five-year cohort translates into real numbers quickly. On a £150,000 interest-only BTL mortgage, a landlord who locked in at 1.75% was paying approximately £219 a month. Refinancing onto a two-year fixed at 5.44% takes that to around £680. The jump is £461 per month on a single property. If rents on that same property rose from £750 to £900 in the same period, the rent growth covered about a third of the mortgage cost increase. On a portfolio of five similar properties, the additional monthly mortgage bill runs above £2,300.
Which properties survive that shock depends almost entirely on the original yield. A North East terrace bought at £90,000 on a 9% gross yield carries enough margin. A South East flat bought at £350,000 on a 4.5% gross yield has never had enough margin at rates above 5%, regardless of how much time the landlord has spent hoping rates would fall before renewal. Those two situations require different responses, and the investors who locked in without acknowledging the difference are feeling it now.
The 43% of new BTL lending above 5% in April is the counter-narrative to the exit headlines. Portfolio investors are still transacting. They are doing it at today's rates rather than waiting for 2021 pricing that will not return. The deals being written above 5% are concentrated in the North, in Bradford BD3 and BD4, Sunderland SR1 to SR3, Middlesbrough TS1 to TS5, Hull HU3 and HU5. Two-bed terraces at £90,000 to £115,000 generating £650 to £800 monthly gross. At 75% LTV on a £95,000 purchase, the interest-only mortgage at 5.44% costs around £362 a month against £720 gross rent. That passes the 145% rental cover stress test and still leaves cash flow after management and maintenance. Not comfortable, but viable.
For landlords whose 2021 five-year fix expires in July, August or September, the June 18 decision creates a specific timing question. Do you fix now at late May rates that have softened from the April peak? Or do you wait six weeks to see the June result? If JP Morgan's rate rise call is correct and Bank Rate moves from 3.75% to 4%, two-year swaps will likely widen and BTL fixed rates could move 25 to 40 basis points higher. For a landlord waiting until July to complete a product transfer, that outcome adds cost to every property in the portfolio for the duration of the new fix.
The Risks Investors Need to Understand
The JP Morgan rate rise prediction for June deserves more attention than it's getting. The April MPC vote wasn't 8-1 to cut or even to hold reluctantly. One member of the nine-person committee actively voted to raise. If the April CPI figure (due in May) or the preliminary May figures signal sticky inflation ahead of June 18, the balance within the committee could shift. The committee is not uniformly dovish. A June rise is not the consensus, but it is not a fringe view either when one member has already voted for it.
Moneyfacts noted that BTL product numbers fell in March 2026 alongside the rate rises. Fewer competing products create pricing problems specifically for non-standard situations: HMOs, multi-unit freehold blocks, limited companies with multiple properties under one entity, borrowers with older adverse credit. The clean single residential BTL at 65% LTV in a straightforward limited company still has options. Move outside that profile and lender appetite shrinks. If your portfolio has complexity, budget for that in your expectation of available rates.
Stress-testing at the current product rate is not enough. Any acquisition modelled on a two-year fix at 5.44% needs to be stress-tested at 6.5% before committing. If the property breaks at 6.5%, the investor is carrying meaningful refinancing risk for the two-year period until the next fix. In northern markets at 9% gross yield, 6.5% stress test typically passes. At 6% gross yield it is marginal. At 5% it does not work at all. Knowing which category your deal falls into tells you whether the rate environment creates an acceptable risk or a structural problem.
Product transfers are underused and often misunderstood. Many lenders allow existing borrowers to move to a new fixed rate product within the same lender without a full underwrite or new affordability assessment. For landlords whose rental income, when assessed at current rates, would not pass a fresh 145% rental cover calculation, a product transfer with the existing lender avoids triggering a new assessment entirely. Not every lender offers this, and the product range on a transfer is often narrower than the open market. But for landlords who would struggle in a full remortgage application, it is worth asking your broker before concluding the only option is exit.
Where the Opportunity Could Be
The 2021 five-year cohort is producing motivated sellers, and in the right markets they're the most interesting stock appearing right now. A landlord who bought a Midlands two-bed at £95,000 with a 1.75% fix, whose property is now worth £120,000 but whose refinancing calculation no longer works, is selling for reasons that have nothing to do with the property's income-generating potential. The new buyer refinances at 5.44%, but enters at a price that reflects the seller's financing stress rather than pure market value. Gross yields on that stock in Birmingham B21 and B12 and Nottingham NG7 and NG8 are running toward 7.5% to 8% at current rents. That is a workable entry in those postcodes.
Bradford BD3 to BD5 and Sunderland SR1 to SR3 are showing similar dynamics at lower acquisition prices. Two-bed terraces in those postcodes at £85,000 to £110,000 with gross monthly rents of £650 to £750 produce yields pushing 9% on the right stock. In those markets, a buyer financing at 5.44% has headroom. The cash flow model works and the capital position is not deteriorating: North East asking prices were +2.7% year-on-year in May 2026 (Rightmove). In Bradford's broader Yorkshire and Humber region, the ONS February 2026 data showed 3.9% annual capital growth. Both at the same time.
For landlords facing their own renewal: fixing before June 18 has a specific logic in the current environment. Two-year products softened slightly in May from the April peak. Taking a two-year fix in the next few weeks hedges against the JP Morgan rate rise scenario at a cost of roughly £60 to £80 per month on a £150,000 loan compared to what was available in late 2025. If June brings a hold and rates drift lower over the following twelve months, a break-and-refix is possible on many products, with the arrangement fee and early repayment charge factored in. If June brings a rise, today's fixers sit on products that look better than anything available post-decision.
The Lombard Odier scenario, 2.75% base rate by Q4 2026, is the scenario where a tracker or short-term variable looks clever in retrospect. A tracker at Bank Rate plus 2% currently runs at 5.75%. If base rate falls to 2.75% through three or four cuts between now and December, that tracker reaches 4.75% before the year is out. On a £150,000 loan the monthly saving versus a two-year fixed at 5.44% runs to around £85 a month from Q4. But the tracker carries full JP Morgan rate rise risk in the upside scenario, and the timeline for Lombard Odier's cuts to materialise runs right through a June meeting where the vote might go the other way.
Arsh's Investor View
I know landlords sitting on 2021 five-year fixes that expire this summer. They all took out those rates for sensible reasons. Some modelled a stress test to 4% at the time and thought that was conservative enough. What they didn't model was 5.75% two-year swaps in the spring of 2026. The ones who bought northern properties at 8% or 9% gross yield are uncomfortable but functioning. The ones who bought London or Surrey stock at 4% to 5% gross yield are having a harder conversation.
The April MPC dissenting vote is what I keep coming back to. The narrative running through the property press is "rate cuts are coming, hold on." But one of nine MPC members voted to raise at the April meeting, not cut. The committee that was expected to be running a deliberate cutting cycle is instead running an 8-1 hold with one active vote to go in the opposite direction. JP Morgan has the institutional apparatus to make forecasts like the June rate rise call stick in the minds of markets even if they're wrong. The risk of being wrong about that prediction while sitting on an unfixed mortgage in July is not symmetric. Fix or transfer to a fix, then watch from a position of certainty.
Product transfers deserve more attention than they get. I've seen two landlords in the past six months who thought they had no choice but to sell because they assumed a full remortgage was the only route when their fix expired, and the rental income at today's rates wouldn't pass the stress test. In both cases there was a product transfer option with the existing lender that kept them in the portfolio. The rate on the transfer wasn't the best available. It was the best available given the constraints. Which in both cases was fine because the rent was still covering the mortgage with some headroom, just not enough to pass a fresh 145% assessment. Ask the question specifically before you draw conclusions about what your options are.
On the broader picture: 43% of new BTL lending above 5% in April 2026 is not a sign of a market on its knees. It is a sign of a market that has repriced and is transacting at the new price. The investors doing those deals have done the regional analysis, found the postcodes where 9% gross yield services a 5.44% mortgage, and got on with it. That is always how this works. The rate environment is the constraint. Strategy is finding the market where the return exceeds the constraint by enough.
How Property Investor App Can Help
Property Investor App lists live BTL and HMO opportunities across the UK, including properties from landlords exiting before or during their next mortgage fix in Birmingham, Bradford, Nottingham, Sunderland and other high-yield markets where the 2021 cohort is most active. For investors looking to benefit from motivated seller pricing in these areas, PIA's deal feed includes off-market and sourced stock with rental income figures included, letting you filter by region and yield band and build a shortlist of properties working above 8% gross at current acquisition costs. For landlords considering their own refinancing options, PIA also connects sellers with the landlord-to-landlord sale market when exit is the cleaner path.
Key Takeaways
- Hamptons April 2026 remortgage analysis: landlords refinancing from 2021 five-year BTL fixes faced a 28.5% average monthly payment increase. Those coming off 2024 two-year deals faced 3.4%. The gap reflects how low rates were when the five-year cohort fixed.
- Average two-year fixed BTL rates moved from 4.66% (1 March 2026) to 5.44% (1 April 2026). Five-year fixed rates moved from 5.05% to 5.75% in the same period. Moneyfacts: BTL costs at a two-year high as of March 2026.
- In April 2026, 43% of all new BTL mortgage applications were agreed at rates above 5%, up from 8% in January. The shift happened in a single quarter, driven by swap rate rises linked to the Iran conflict and energy price pressure.
- Bank of England held at 3.75% on April 29, 8-1 vote. The dissenting vote was to raise to 4%, not to cut. Next MPC decision: June 18. JP Morgan forecasts a rate rise; Lombard Odier forecasts 2.75% by Q4 2026; market consensus expects a hold.
- On a £150,000 interest-only BTL loan, moving from 1.75% to 5.44% increases monthly payments from approximately £219 to £680. Cash flow impact is concentrated in lower-yield southern properties where there was never enough margin to absorb this.
- Product transfers with existing lenders can allow landlords to refix without a new affordability assessment, which matters where the passing rent at today's stress-test rates would not support a full remortgage application.
Frequently Asked Questions
Why are landlords who fixed in 2021 facing such a large mortgage cost increase?
Five-year BTL fixed rates taken out in 2021 were priced when Bank Rate was 0.1% and specialist limited company products were available from around 1.5% to 2.2%. Bank Rate subsequently rose to a peak of 5.25% in 2023 before falling to 3.75% today. Two-year fixed BTL rates averaged around 5.44% in April 2026. Hamptons data published in May 2026 shows landlords refinancing from 2021 five-year deals experienced an average 28.5% increase in monthly mortgage payments. On a £150,000 interest-only loan, that is roughly £460 more per month compared to the expiring rate. Properties with high gross yields (8%+) in northern markets have the cash flow headroom to absorb this. Lower-yield properties in London and the South East generally do not.
Should I fix my BTL mortgage before the Bank of England June 18 decision?
The case for fixing before June 18 is straightforward if you believe there is any meaningful probability that JP Morgan's rate rise prediction for that meeting is correct. One MPC member voted to raise at the April 29 meeting, not to cut. If the June 18 vote moves in that direction and Bank Rate goes from 3.75% to 4%, two-year swap rates will likely widen and BTL fixed products could price 25 to 40 basis points higher within days. Fixing now at late May rates locks in current pricing. If June brings a cut instead, the cost of having fixed early is modest: a potential break-and-refix at an arrangement fee, or accepting the existing rate until the next renewal. Ask your broker for specific rates available today and model the difference before deciding.
What BTL mortgage rates are available for landlords in May 2026?
Two-year fixed limited company BTL rates in late May 2026 sit around 5.4% to 5.6% for standard residential properties at 75% LTV with specialist lenders. Five-year fixed rates are in the 5.7% to 6.0% range. HMO and multi-unit freehold block products carry a premium of 20 to 50 basis points over standard residential rates. At 65% LTV the best two-year products from some lenders are approaching 5.0%. Product availability is narrower than it was in 2024: BTL product numbers fell in March 2026 as rates rose and some lenders restricted criteria. Rates have softened slightly in May from the April peak as swap rates partially reversed. Check with a specialist BTL broker for current best-buy products specific to your property type and limited company structure.
Is it worth waiting for Bank of England rate cuts before remortgaging a buy-to-let?
That depends on the timeline of expected cuts and your current product situation. Lombard Odier forecasts base rate reaching 2.75% by Q4 2026, which would push two-year fixed BTL rates toward 4.5% to 5% if the cut path materialises. Against that, JP Morgan is forecasting a rate rise in June 2026, and one MPC member already voted to raise at the April meeting. A landlord whose current fix has expired and is sitting on a standard variable or revert rate is paying significantly more than available fixed alternatives while waiting for cuts that may not arrive on the assumed timeline. The asymmetric risk argument is that fixing now at 5.4% and being proved wrong by cuts costs a modest amount; waiting for cuts that don't come costs the difference between the revert rate and the fixed product for the entire waiting period. Product transfers with existing lenders are also worth exploring before committing to a full remortgage.
What should landlords do if their 2021 five-year fix is expiring?
First, check your options with a specialist BTL mortgage broker at least three months before the fix expires. Most fixed products can be booked three to six months ahead at the rate available on booking date, protecting against rate rises before completion. Second, ask specifically about product transfers with your existing lender before approaching new lenders: a product transfer can allow a refix without a new affordability assessment, which matters if rental income at today's stress-test rates would be borderline in a full remortgage application. Third, run the cash flow on the new rate for your specific property, not on a regional average. A property at 9% gross yield in the North East works at 5.44%. A property at 4.5% gross yield in the South East does not, regardless of what the national averages suggest. If the numbers genuinely don't work at the new rate, selling to another landlord before the fix expires can be more efficient than a distressed sale post-maturity.
