How will the new Renters' Rights Act impact mortgage eligibility criteria for buy-to-let properties, and what changes should I anticipate from lenders?
Quick Answer
The upcoming Renters' Rights Bill, particularly the abolition of Section 21, is set to increase lender scrutiny on buy-to-let rental income stability, potentially leading to adjusted stress tests and more stringent mortgage eligibility criteria.
## Will the Renters' Rights Act Affect My Buy-to-Let Mortgage Eligibility?
The Renters' Rights Act 2025, specifically the abolition of Section 21 'no-fault' evictions from 1 May 2026, is anticipated to influence buy-to-let (BTL) mortgage eligibility criteria. Lenders operate on risk assessment; changes in landlord's ability to regain possession directly impact their perceived risk of rental voids and arrears, which underpins mortgage security.
Historically, the swift process of Section 21 offered a degree of assurance regarding possession. Its removal means lenders will likely place greater emphasis on a landlord's ability to manage tenancies and adhere to new, strengthened possession grounds. This shift means that while the specific BTL mortgage rates themselves aren't directly legislated, the underlying serviceability and stress tests applied by lenders are likely to evolve to reflect this heightened risk. Always compare the latest rates, as typical BTL fixes vary by lender and product.
## How Might Lenders Adjust Their Underwriting Criteria?
Lenders are expected to adjust their underwriting criteria by increasing scrutiny on several fronts. The Interest Cover Ratio (ICR) is a primary tool for assessing affordability, and a common conservative example is 125% rental coverage at a 5.5% notional pay rate, although many lenders use 140% or higher. With the Renters' Rights Act, some lenders may increase their ICR requirements further or apply higher notional interest rates in their stress tests, making it harder for properties to qualify based on rental income alone.
For example, a property generating £1,000 per month in rent might currently pass an ICR at 125% of a 5.5% notional rate. If the lender increases this to 145%, the required rent would jump to £1,160 to service the same notional mortgage payment, potentially necessitating a larger deposit or a search for a higher-yielding property. This change fundamentally impacts the loan amount an investor can secure against a given property.
Lenders may also place more importance on a landlord's experience and property management track record. For first-time landlords, this could translate into requirements for larger deposits or more stringent background checks. Furthermore, portfolios with a history of frequent tenant disputes or arrears might face more challenging terms, as the perceived difficulty in resolving such issues increases without Section 21.
## What Specific Changes Should I Anticipate from Lenders?
Investors should anticipate several specific changes in lender behaviour and criteria. Firstly, expect an increase in the proportion of the rental income required to cover mortgage payments. As noted, if an investor was previously approved with an ICR at 125% of a reference rate, this might rise to 140% or even 150% with some lenders, pushing down the maximum loan amount available for a given rent.
Secondly, lenders might differentiate between properties or landlords more stringently. For instance, properties in areas with higher tenancy dispute rates could be subject to higher risk weighting. New landlords, or those expanding rapidly, might be asked for larger deposits—perhaps 30% instead of 25% for a typical BTL loan—or face higher arrangement fees to offset the increased perceived risk.
Thirdly, there may be a shift towards preferring landlords who use reputable letting agents or demonstrate robust property management practices. Lenders might introduce new clauses in offer letters or terms and conditions requiring landlords to demonstrate compliance with the new Act, including providing clear evidence of maintenance and tenant communication. This could be viewed as a way to mitigate the risk associated with more complex possession processes. Overall, the emphasis will be on demonstrating sustainable, well-managed tenancies, which ultimately supports the long-term viability of the investment for both landlord and lender.
## Positive Underwriting Shifts for Proactive Landlords
While the Renters' Rights Act introduces new challenges, it also presents opportunities for landlords who proactively manage their properties. Lenders may begin to favour landlords who demonstrate exceptional compliance with tenant welfare standards and have robust maintenance schedules.
For example, a landlord with a proven track record of timely repairs, high EPC ratings (current minimum E, moving to C by October 2030), and excellent tenant communication could potentially be viewed more favourably. This might translate into access to better rates or more flexible terms, as their properties represent a lower risk of tenant disputes and subsequent lengthy possession processes. This is about rewarding good practice.
## Challenges and Potential Hurdles for Less Prepared Investors
Conversely, landlords who are less organised or struggle with property maintenance and tenant relations may face significant hurdles. The increased difficulty in regaining possession without Section 21 means that issues such as rent arrears or property damage will require more thorough and compliant management under the new grounds for possession. This could lead to extended periods of non-payment or increased costs for legal action.
For example, a landlord struggling with an ongoing repair issue could find that their ability to secure new finance is hampered if a lender perceives a higher risk of tenant complaints and potential rent withholding. This could also result in higher interest rates or stricter covenants on their BTL mortgage products, potentially making some investments unviable. Therefore, meticulous property management becomes paramount.
## Investor Rule of Thumb
Post-Renters' Rights Act, lenders will prioritize lower-risk, professionally managed tenancies; expect higher ICRs and greater scrutiny of landlord experience and property condition.
## What This Means For You
Many landlords won't proactively review their portfolio's financial modelling or operational readiness for these legislative shifts.

Steven's Take
The abolition of Section 21 is a significant change, not just for landlords but for lenders too. Their risk models are adapting to a world where regaining possession is more prescriptive. From my experience building a £1.5M portfolio, anticipating these shifts and maintaining a high standard of property management and tenant relations is key. Lenders will increasingly favour landlords who can demonstrate they run their properties like a professional business, with clear processes for everything from maintenance to communication. Don't wait for your next mortgage renewal to understand these changes; proactively engage with them now.
What You Can Do Next
Review your current BTL mortgage terms and conditions, focusing on any clauses relating to tenant possession and landlord obligations – check your lender's website or contact your mortgage advisor for updated guidance.
Calculate your current Interest Cover Ratio (ICR) for all properties using a higher notional rate (e.g., 140% at 5.5% or 6%) to assess future affordability – use online BTL mortgage calculators or consult a specialist broker.
Familiarise yourself with the new grounds for possession under the Renters' Rights Act 2025 – refer to official government guidance on gov.uk/renters-rights-act for details.
Proactively improve your property management processes, ensuring robust tenant communication, regular maintenance, and meticulous record-keeping – consider using property management software or a reputable letting agent.
