As we approach the end of 2025, many landlords are focusing on year-end accounts, tax planning, and tenant renewals. But there’s one area that can have a bigger impact on your bottom line than almost anything else: your mortgages.
If your fixed rate ends in 2026 – or even late 2025 – now is the time to act. Lenders are signalling tighter criteria next year, regulatory expectations are evolving, and energy performance is climbing rapidly up the agenda. Landlords who wait until the renewal letter arrives risk reduced choice, higher costs, and unnecessary stress.
At NetRent, we specialise in helping landlords plan ahead. This post is your reminder – and your nudge – to get your mortgage options reviewed before the New Year rush.
1. Why Leaving Renewals to the Last Minute Is So Risky
Many landlords still treat remortgaging as a “job for next month”. In today’s market, that approach is expensive.
Waiting until a few weeks before your deal ends can lead to:
-
Falling onto the Standard Variable Rate (SVR) – often 2–3% higher than your fixed rate, costing hundreds per month.
-
Limited product choice – especially if lenders tighten stress testing or reduce LTVs in early 2026.
-
Time pressure – valuations, underwriting questions and legal work all take time; if there’s a hiccup, you have no buffer.
-
Missed opportunities – such as releasing equity for improvements or securing a longer fixed term ahead of possible future volatility.
By contrast, starting the process four to six months before renewal gives you maximum control and flexibility.
2. What a Proper Renewal Review Should Actually Include
A professional mortgage review isn’t just about checking whether your rate is going up. It should be a full health check on your borrowing and your portfolio. At a minimum, you should be asking:
-
Can I beat my existing lender’s offer on the open market?
-
Is it the right time to release equity for improvements or expansion?
-
Does this renewal give me the chance to switch to a better structure – for example, into a limited company (SPV) product?
-
Are there green or EPC-linked products that reward my property’s efficiency?
-
Would it be smarter to fix for longer to protect cash flow into the 2030s?
If your current approach to renewal is just “accept the first offer that arrives”, you’re almost certainly leaving money on the table.
3. Why Acting Before 2026 Matters
With around 7–8 weeks left of 2025, there is still a valuable window to get ahead of lender changes expected next year.
By reviewing and securing options now, you can:
-
Lock in today’s criteria before stress tests and portfolio checks tighten further.
-
Get into the underwriting queue before the usual surge in applications in January and February.
-
Use current valuations and lending appetite to your advantage, especially where you’ve seen capital growth.
-
Plan energy upgrades or refurbishment projects with a clear funding strategy in place.
The message is simple: the earlier you start, the more choice you have.
4. How NetRent’s Renewal Review Works
Our role is to take the pressure off landlords and turn renewals into an opportunity rather than a chore. A typical NetRent review will include:
A. Portfolio Overview
We look at your whole position – not just one mortgage. That includes:
-
Current rates, terms and expiry dates
-
Loan-to-value (LTV) across each property
-
Rental performance and yield
-
Ownership structure (personal vs SPV)
B. Affordability and Stress Testing
We run your figures through current lender models so there are no surprises:
-
Can your rental income meet lender stress rates?
-
Are there properties that might struggle under tighter 2026 rules?
-
Would adjusting borrowing, term or structure improve approvals?
C. Market Scan and Product Matching
We then search across a wide panel of mainstream and specialist lenders to identify:
-
Cheaper or more flexible replacement products
-
Green / EPC-friendly options
-
Opportunities to release equity or consolidate debt
-
Longer-term fixes that secure your costs well beyond 2026
D. A Clear, Actionable Plan
You’ll get a straightforward set of recommendations: what to refinance now, what to leave, and where the biggest gains or savings are likely to be.
5. A Reminder for Letting Agents
If you’re a letting agent this is also the time to encourage your landlords to act early.
-
Landlords with stable, well-financed properties are less likely to panic-sell, reducing churn in your managed portfolio.
-
Proactive remortgaging can fund EPC upgrades, helping meet local and national standards.
-
Joint planning between landlords, agents and NetRent can ensure properties remain safe, compliant and mortgageable long-term.
If you support a group of landlords, a coordinated review ahead of 2026 can make a real difference to the stability of your local rental market.
6. Your “Last Call” Checklist Before 2026
If you do just five things before the end of 2025, make it these:
-
List your renewal dates for the next 12–24 months.
-
Identify any mortgage ending in 2026 – these are priority.
-
Gather key documents: tenancy agreements, rental figures, EPCs, insurance, company accounts.
-
Think about your plans: are you expanding, consolidating, or upgrading?
-
Book a mortgage review call with a specialist broker – ideally before the New Year rush.
You don’t need every detail nailed down to start the conversation. You just need the willingness to plan ahead.
Final Thoughts: Don’t Wait for the Renewal Letter
Your renewal letter is a reminder – not a strategy.
Landlords who simply accept whatever their existing lender offers will almost always pay more, borrow less, or miss out on growth. Landlords who plan ahead, compare the market, and structure finance properly will be the ones who thrive in 2026 and beyond.
