What mortgage products or lending criteria changes does the Imla forecast suggest for buy-to-let investors in 2026-2027?
Quick Answer
IMLA forecasts for 2026-2027 suggest a stable buy-to-let mortgage market, with limited new product lines but a continued focus on affordability, portfolio assessment, and energy efficiency reflecting regulatory trends.
## Anticipated Stability and Focused Evolution in Buy-to-Let Lending
For 2026-2027, Imla forecasts point towards a period of stabilisation rather than revolutionary change in the buy-to-let mortgage market. The focus will likely remain on refining existing product lines and criteria to navigate the ongoing economic landscape and regulatory shifts. Key areas for landlords to consider include:
* **Continued Affordability Scrutiny**: Lenders will maintain stringent stress tests, likely requiring rental coverage ratios of 125% at a notional rate around the current Bank of England base rate of 4.75% plus a margin, or even higher, to ensure properties are profitable. This means a property generating £1,000 in rent would need to cover interest repayments of roughly £800 at a 5.5% stress rate. For instance, a £200,000 loan at 5.5% interest costs about £917 a month. If the rent is £1800, that covers the stress rate, but if it's only £1200, it wouldn't pass the typical stress test.
* **Portfolio Lending Refinement**: For landlords with multiple properties, lenders will continue to assess the overall portfolio financial health, not just individual assets. This holistic approach helps manage risk for both the lender and the investor. Understanding your overall portfolio debt service coverage ratio (DSCR) will be crucial.
* **Emphasis on Energy Efficiency**: With the proposed minimum EPC rating of C by 2030 for new tenancies, lenders will increasingly factor EPC ratings into their underwriting. We're already seeing green mortgages, and this trend will accelerate, potentially offering better rates for higher EPC-rated properties or requiring plans for improvements.
* **Limited New Product Innovation**: Given the current economic climate and regulatory landscape, Imla suggests that entirely new, groundbreaking mortgage products are less likely. Instead, expect tailored versions of existing products, perhaps with specific criteria for HMOs or multi-unit freeholds designed to meet slightly different risk profiles.
* **Adaptation to Section 24 Impacts**: The full effect of Section 24, where mortgage interest is no longer deductible for individual landlords, continues to shape lending. Companies borrowing through a limited company are exempt from this, meaning continued favourability for corporate structures in BTL lending, potentially even more so than individual borrowing.
## Potential Challenges and Areas for Caution
While stabilisation is generally positive, buy-to-let investors need to be aware of potential watchpoints:
* **Persistent Higher Interest Rates**: The Bank of England base rate, currently at 4.75%, is not expected to fall dramatically. This means higher borrowing costs will likely persist, impacting cash flow and reducing profit margins for many buy-to-let investors. Typical BTL mortgage rates could remain in the 5% to 6.5% range.
* **Increased Regulatory Scrutiny**: The Renters' Rights Bill, with Section 21 abolition expected in 2025, and Awaab's Law extending to the private sector, signal continued regulatory focus on landlord responsibilities. Lenders will be keen to ensure landlords are compliant, potentially adding more checks to their processes.
* **Valuation Challenges for Older Stock**: Properties with lower EPC ratings or significant repair requirements could face tougher valuations or higher lending hurdles as the 2030 EPC deadline approaches, impacting both purchase and refinancing potential.
* **Tightened Deposit Requirements**: While not a direct Imla forecast, if house price growth remains flat or negative, lenders may become more cautious, potentially increasing required deposit percentages or reducing loan-to-value (LTV) offerings.
## Investor Rule of Thumb
Future-proof your buy-to-let investments by prioritising strong rental yields, energy efficiency upgrades, and a clear understanding of your overall portfolio's financial health, as these elements will become increasingly critical for securing advantageous lending.
## What This Means For You
The landscape is evolving, and staying ahead of lending criteria and market trends is not just smart, it's essential. Understanding how stress tests, EPC regulations, and portfolio assessments impact your next deal can be the difference between a profitable venture and a missed opportunity.

Steven's Take
The Imla forecasts for 2026-2027 really hammer home that the focus needs to be on solid, foundational investing. We're unlikely to see radical shifts in mortgage products; instead, it's about lenders getting smarter with how they assess risk on existing offerings. This means your numbers have to stack up even more rigorously. Stress tests won't ease up much, and with the proposed EPC changes down the line, lenders are already looking at property standards. For us, this means deals need to be robust from the get-go, with strong yields and a clear path to maintain property quality. Don't chase deals that barely scrape through the stress test today, because tomorrow's criteria might be even tougher. Look at your overall portfolio profitability and how you can add value through energy efficiency, which is becoming a prime consideration for sustainable growth.
What You Can Do Next
Review Your Portfolio's EPC Ratings: Identify any properties currently below a C rating and start budgeting for necessary upgrades to meet future requirements, potentially unlocking better 'green mortgage' rates.
Understand Current Stress Tests: Calculate your rental coverage ratio (ICR) using a notional rate of 5.5% or higher to ensure your existing or prospective properties can comfortably meet lender demands.
Consider Limited Company Structure: Evaluate if holding new buy-to-let investments within a limited company aligns with your investment strategy, as this structure largely bypasses Section 24 restrictions on mortgage interest deductibility for individuals.
Build a Strong Relationship with a Broker: Work with a specialist buy-to-let mortgage broker who understands the nuances of portfolio lending and can navigate stricter criteria to find the best products for your specific circumstances.
