Buy-to-let mortgage rates look set to climb again after a period of falling pricing and heavy competition between lenders. SWAP rates are rising, several major lenders have already repriced, and a new government is reopening debate on rent controls and landlord taxation.
There are still ways for landlords to protect their position, but doing so means acting early and keeping a close eye on how the market moves over the coming weeks.
Why SWAP rates matter for landlords
Movement in SWAP rates is the biggest factor behind this shift in mortgage pricing. Lenders use SWAP rates as one of the key inputs when pricing fixed-rate mortgages, so when they rise, funding costs for lenders typically rise too, and mortgage rates tend to follow.
Two-year SWAP rates have climbed to around 4.2%, while five-year SWAP rates now sit at approximately 4.29%. Geopolitical tensions and concerns over future inflation have driven that increase, reversing some of the gains landlords saw during the recent price war between lenders.
Inflation data itself has looked encouraging, but markets remain wary that higher energy and shipping costs could put fresh pressure on prices in the months ahead. For landlords approaching a remortgage or a new purchase, the safest assumption right now is that rates won't keep falling.
Lenders are already repricing
That shift in SWAP rates has already started showing up in lender pricing. In recent weeks, a number of major lenders have increased their rates, including:
- Nationwide
- The Mortgage Works
- NatWest
- Barclays
- Coventry Building Society
- Paragon
- Keystone
- Rely
Brokers report that lenders are often giving only a few hours' notice before withdrawing a product or repricing it, sometimes flagging changes during the afternoon that take effect later the same day. A mortgage rate is generally only secured once a full application has reached the lender, so landlords who've found a product that fits their circumstances have little room to sit on a decision.
A new government, and a shifting policy landscape
Political change is always worth watching closely where housing is involved, and this shift has brought a fresh cabinet with it. Angela Rayner has returned as secretary of state for housing, communities and local government, Matthew Pennycook remains housing minister, and John Healey has been appointed chancellor.
Much of what comes next remains speculative, but a few themes stand out. Existing planning reforms and housing delivery targets look set to continue, alongside support for a larger council housebuilding programme. For the private rented sector specifically, the sharper concerns lie elsewhere.
Rent freezes have generated considerable discussion as part of a broader cost-of-living package, though nothing has been confirmed and any freeze remains under consideration rather than policy. Landlords are understandably wary of what such a measure could mean for returns across the private rented sector, but for now the more useful approach is to stay informed rather than react to speculation.
Tax reform is arguably the bigger long-term question for property investors. Ideas reportedly under discussion include changes to capital gains tax on residential property, a possible national insurance charge on rental income, and wider reform of property taxation generally.
One proposal getting particular attention would replace both council tax and stamp duty with a proportional property tax, under which investment properties and second homes could face notably higher charges than owner-occupied homes. None of this is confirmed government policy, but landlords would be wise to track the direction of travel and think through how any of these changes could affect portfolio profitability.
Deadlines landlords shouldn't miss
Alongside the political backdrop, several operational deadlines remain live. Landlords relying on a Section 21 notice served before 1 May have until tomorrow, 31 July to apply for court possession; after that, any claim will need to rely on alternative grounds instead. Student landlords should also check notice requirements and deadlines tied to Section 8 Ground 4A.
Further down the line, plans remain in place for a private rented sector database, a landlord ombudsman, and greater digitisation of court processes, with these reforms expected to continue rolling out over the coming years.
Where a portfolio review can help
When uncertainty rises, it's usually worth focusing on what's actually within your control. For landlords concerned about rising mortgage costs, higher operating expenses or potential legislative change, reviewing rental income, property values, outstanding borrowing and current mortgage rates can help identify ways to reduce finance costs, improve cash flow, strengthen resilience across a portfolio, and get ahead of future regulatory or tax changes.
Whether you're approaching a remortgage, weighing up a new purchase or simply reviewing an existing portfolio, small adjustments made now can carry real weight in a market that's shifting this quickly.
