The Great 2026 Buy-to-Let Remortgage Rush: Is Your Portfolio Ready?
If you are a landlord looking at your mortgage documentation this month, you are not alone. 2026 is shaping up to be a monumental year for the Buy-to-Let (BTL) market. There is a significant wave of refinancing activity already underway.
According to new research released by Paragon Bank this February, approximately 39% of landlords, nearly four in ten, plan to refinance their rental properties during 2026. This represents a substantial remortgage cycle. UK Finance data indicates that 1.8 million homeowners overall are due to remortgage in 2026. Many of these homeowners will be coming off historically low five-year fixed rates.
At Mandalay Financial, we are helping landlords navigate this busy market to ensure they secure the best possible rates for their portfolios. Here is what is driving the surge and how it affects you.
The Legacy of 2021
To understand the current market, we have to look back five years. 2021 was a record-breaking year for the BTL sector, fueled largely by the Stamp Duty holiday. As a result, many landlords rushed to purchase properties or lock in deals during that period. They typically opted for five-year fixed-rate mortgages.
Now, as we move through 2026, those deals are maturing. The volume is substantial: it is estimated that £49.7 billion in fixed-rate BTL mortgages will mature in the 12 months leading up to November 2026. Consequently, this concentrated maturity schedule is creating the perfect conditions for what we are calling the “Great Remortgage Rush.”
Data from the Intermediary Mortgage Lenders Association (IMLA) supports this trend, forecasting a 25% cumulative rise in BTL lending by the end of 2026. Buy-to-let lending is expected to reach £44 billion in 2026 alone. Additionally, buy-to-let remortgages have already surged 23% year-on-year to October 2025. This demonstrates the momentum building in this sector.
Who is Refinancing?
The data suggests that portfolio landlords are the most active participants in this remortgage wave. Those with larger portfolios (four or more properties) are significantly more likely to be planning a refinance compared to those with fewer assets. On average, landlords anticipate refinancing 2.2 properties each this year.
Interestingly, despite the trend toward limited company ownership in recent years, the majority of these expected refinances (78%) are set to be in a personal name. This indicates that many landlords who purchased during the 2021 boom did so before the regulatory and tax landscape fully shifted toward corporate structures.
The scale of activity means that experienced landlords are treating 2026 as a strategic pivot point. It is an opportunity not just to secure better rates, but to fundamentally reassess their portfolio structure and growth plans.
The Interest Rate Opportunity
One of the primary drivers making 2026 an opportune time to remortgage is the improving interest rate environment. The Bank of England is forecast to gradually reduce the Base Rate through 2026 to the 3.0%-3.75% range. This will create a more favourable borrowing climate than many landlords have seen in recent years.
Leading two-year fixed rates are now available from just over 3.5%, while five-year equivalents start from just over 3.7%. Industry analysts predict that average five-year fixed buy-to-let mortgage rates will settle around 4.5% by the end of 2026: a significant improvement for landlords currently on higher rates.
This rate environment directly impacts two critical metrics for landlords: lower monthly interest payments and enhanced ability to pass lender rental coverage stress tests. These tests require rent to cover mortgage payments plus a safety margin. For many landlords, this could be the difference between maintaining profitability and struggling with cash flow.
Opportunity for Improvements
Refinancing isn’t just about finding a new rate; it is also a strategic opportunity to release capital.
Many landlords are using this maturity window to withdraw equity to fund property improvements. In 2025 alone, landlords withdrew nearly £1.1 billion via remortgages specifically to fund property improvements. This represents a 54% increase in renovation-focused borrowing. With upcoming regulations regarding property standards and energy efficiency on the horizon, 2026 serves as the perfect time to raise the funds needed to future-proof your investments.
The rental yield landscape remains robust despite some cooling from recent peaks. The UK average rental yield sits at approximately 5.96%, with regional hotspots in the North East and Midlands consistently delivering yields exceeding 7% gross. However, annual rent growth is forecasted to slow to 2-2.5% in 2026 from recent highs. Persistent housing supply shortages continue to underpin strong tenant demand and occupancy rates.
This combination of factors: lower borrowing costs and steady rental income, creates a favourable environment for landlords to invest in their properties while maintaining healthy returns.
Why You Need a Broker in 2026
With nearly £50 billion of mortgages looking for a new home, lenders are competing for business. However, the landscape is vastly different from 2021.
If your fixed rate is ending, simply accepting your lender’s product transfer offer might not be the most cost-effective move. With nearly 40% of the market moving at once, it is vital to have a clear view of the entire lending landscape.
This is where Mandalay Financial can help.
As expert mortgage brokers, we can:
Scan the whole market to find competitive rates that match your specific LTV and rental income profile. The difference between a decent rate and the best available rate can translate to thousands of pounds over the term of your mortgage.
Advise on structure, helping you understand the implications of refinancing personally versus other options. The market is increasingly sophisticated, with more landlords diversifying into mixed-use properties and HMOs in search of risk mitigation and greater yields.
Manage complex portfolios, ensuring that if you are refinancing multiple properties (like the average landlord this year), the process is streamlined and efficient. We coordinate timing, documentation, and lender requirements so you can focus on managing your properties.
Assist with capital raising if you plan to withdraw equity for renovations or regulatory upgrades. We help structure your remortgage to release the funds you need while maintaining strong affordability metrics that satisfy lenders.
Secure Your New Deal Today
Don’t wait until your current deal expires to start looking. With the high volume of applications expected this year, getting ahead of the curve is essential. Lenders are processing record numbers of applications. By starting the conversation early, you have time to explore all your options without the pressure of an imminent deadline.
The 2026 remortgage wave represents both a challenge and an opportunity. Landlords who approach it strategically, viewing refinancing not just as a rate-chasing exercise but as a chance to optimise their portfolio structure and funding, will be best positioned for long-term success.
