What mortgage products or rates should buy-to-let investors anticipate for remortgaging in 2026?
Quick Answer
Buy-to-let investors remortgaging in 2026 should expect rates between 5.0-6.5% on typical fixed products, with lenders applying a 125% rental stress test at around a 5.5% notional rate.
## Anticipate Competitive Buy-to-Let Mortgage Products
For buy-to-let investors looking to remortgage in 2026, the mortgage product landscape will likely remain robust, albeit with an emphasis on affordability and stress testing. Whilst the **Bank of England base rate** currently stands at 4.75% (December 2025), this forms the foundation for BTL mortgage pricing. We're currently seeing typical BTL mortgage rates ranging from 5.0-6.5% for 2-year fixed products, and 5.5-6.0% for 5-year fixed products. These rates aren't massively influenced by what the UK property market is doing in terms of sales, but more by the health of the lending market and international finance. Lenders continue to offer various options, including:
* **Fixed-Rate Mortgages**: These remain highly popular for BTL investors seeking payment stability. Expect 2-year, 3-year, and 5-year fixed options to be widely available, with 5-year fixes often offering slightly less stringent stress tests. Securing a 5-year fixed rate now could mean certainty over repayments for a significant period. For example, on a £200,000 mortgage at 5.5% interest, your monthly interest-only payments would be £916.67. This certainty is vital for cash flow planning, especially with Section 24 impacting profitability.
* **Tracker Mortgages**: While less common for new BTL purchases, trackers may still feature for remortgaging, appealing to those who believe the base rate might decrease. These typically track the Bank of England base rate plus a set margin. However, the volatility means careful consideration is needed.
* **Interest-Only Mortgages**: The standard for BTL, allowing investors to maximise cash flow by only paying the monthly interest. The capital repayment is planned for sale or refinancing, which is important to remember. If you're looking at your exit strategy, understanding how your mortgage plays into it is key.
* **Limited Company Mortgages**: As more investors shift to holding properties in a limited company structure due to **Section 24**, the availability and product range for limited company BTL mortgages are set to expand further. Corporation Tax at 19% (for profits under £50k) is more favourable than higher rate income tax for many landlords.
## Key Challenges and Considerations for Remortgaging
While products will be available, investors need to be aware of several factors that could complicate remortgaging in 2026, including looking at scenarios for remortgaging a rental property with current conditions. The market has changed significantly, and what worked a few years ago might not today. Pay close attention to:
* **Stress Test Margins**: The standard BTL stress test requires 125% rental coverage at a notional rate, usually around 5.5%. As interest rates have risen, achieving this calculation demands higher rental income, or a larger deposit if you're looking to purchase. If your rent can't cover 125% of the hypothetical mortgage payment at 5.5%, you might struggle to remortgage with a new lender or even your existing one on better terms. A £1,200 monthly rent would need to generate an income buffer of £300 to meet a £900 mortgage payment at the stress test rate. This impact on **buy-to-let investment returns** is huge.
* **Property Valuation**: Lenders will conduct a new valuation. If property values have declined in your area, or if your property condition has deteriorated, this could impact your Loan-to-Value (LTV), potentially requiring a higher deposit to secure the best rates.
* **EPC Requirements**: While the proposed minimum EPC rating of C by 2030 for new tenancies is under consultation, lenders are increasingly factoring energy efficiency into their product offerings. Properties with lower ratings might face less favourable terms or even difficulties securing finance from some providers. This is a common question from landlords asking about **ROI on rental renovations** and improvements.
* **Lender Criteria**: Each lender has specific criteria. Some may prefer certain property types, locations, or landlord experience levels. It’s crucial to speak with a broker who understands the nuances of the BTL market and can compare different lender options.
* **Awaab's Law and Renters' Rights Bill**: Upcoming legislation regarding damp/mould and the abolition of Section 21 could influence lender confidence and criteria. These changes mean landlords must ensure their properties meet high standards, potentially affecting their ability to secure remortgages if properties fall short.
## Investor Rule of Thumb

Steven's Take
The increase in the Bank of England base rate to 4.75% and the associated higher mortgage rates are here to stay for a while. We're seeing more landlords consider limited company structures to mitigate Section 24's impact on their rental income. Don't just accept your existing lender's offer without exploring options. With stress tests so high, proving your property's profitability is more critical than ever. The focus isn't just on getting a rate, but on securing finance that maintains your cash flow and portfolio growth. Getting a good mortgage broker is key here.
What You Can Do Next
Review your current mortgage terms and note the end date of any fixed or tracker period.
Calculate your current rental yield and ensure it meets or exceeds typical stress test requirements (125% rental coverage at 5.5% notional rate).
Obtain an up-to-date property valuation to understand your current LTV (Loan-to-Value).
Assess your property's EPC rating and consider any necessary improvements to meet future standards.
Engage with a specialist buy-to-let mortgage broker to explore all available products, including limited company options, and identify the best rates and terms for your specific circumstances.
