What new high LTV buy-to-let mortgage products are available from CHL and do they suit my investment strategy?

Quick Answer

Assessing specific CHL Buy-to-Let products requires direct inquiry as lenders' offerings frequently change. High LTV products generally suit strategies where you want to minimise upfront capital, but come with higher interest rates and stricter stress tests.

When considering buy-to-let mortgage products, particularly from specialist lenders like CHL Mortgages, it's essential to understand that 'high LTV' in the BTL space isn't quite the same as it is for residential mortgages. While a 90% or 95% LTV might be available for a primary residence, BTL products rarely exceed 80% LTV, and often carry significantly different terms when moving above 75%. As of December 2025, the market is navigating a Bank of England base rate of 4.75%, which has pushed typical BTL mortgage rates to 5.0-6.5% for 2-year fixed deals and 5.5-6.0% for 5-year fixed deals. This higher cost of borrowing, coupled with increased stress testing, means that what constitutes 'suitable' for an investment strategy has shifted considerably. CHL Mortgages, a dedicated buy-to-let lender, focuses on professional landlords and a range of property types beyond standard single tenancy agreements, often offering products for Houses in Multiple Occupation (HMOs), multi-unit freehold blocks (MUFB), and holiday lets. While they do offer competitive rates across various LTV tiers, their 'higher' LTV products, typically around 75% to 80%, are designed for experienced investors seeking to maximise their leverage, rather than for those with minimal deposits. ### Buy-to-Let Mortgage Features to Consider Now * **Higher LTV Availability and Costs**: While CHL might offer products up to 80% LTV, these usually come with higher arrangement fees or increased interest rates compared to a 65% or 70% LTV product. For instance, a 75% LTV product could carry a rate of 6.2% with a 2% arrangement fee, whereas an 80% LTV might be 6.5% with a 3% fee. This means a larger portion of your rental income could be consumed by finance costs, impacting your net yield. For an investor buying a £250,000 property with an 80% LTV, a £200,000 mortgage at 6.5% interest means annual interest payments of £13,000 before any capital repayment. This is a significant fixed cost to factor into your calculations. * **Stress Testing**: All BTL lenders, including CHL, will apply a stress test to ensure the property's rental income can comfortably cover the mortgage payments. The standard BTL stress test is currently 125% rental coverage at a notional rate of 5.5%. For higher LTV products, some lenders might apply an even higher notional rate, perhaps 6.0% or 6.5%, or require a higher interest cover ratio (ICR) of 145% or 160% to mitigate their risk. This can significantly limit your borrowing capacity, especially in areas with softer rental yields. * **Product Flexibility**: CHL often caters to more complex property structures such as HMOs, which can generate higher rental income but also come with more stringent licensing and regulatory requirements. For HMOs with 5+ occupants forming 2+ households, mandatory licensing is required, and minimum room sizes like 6.51m² for a single bedroom or 10.22m² for a double must be met. This specialisation can be a benefit if your strategy involves these types of properties, as mainstream lenders might not offer products for them. * **Exit Strategy Considerations**: Higher LTV lending often implies a higher risk for the lender, which can translate into early repayment charges (ERCs) that are longer or more punitive. Understanding your planned hold period and exit strategy is crucial to avoid incurring significant penalties if you need to sell or refinance earlier than anticipated. ### Suitability for Your Investment Strategy Whether CHL's high LTV products suit your strategy hinges on several factors, including your experience level, the type of property you're acquiring, and your long-term goals in the current market climate. * **Experienced Landlords**: If you're an experienced landlord with a proven track record, understanding of the market, and robust cash reserves, high LTV products can be a tool for portfolio expansion. CHL typically favours professional landlords who can demonstrate their ability to manage properties and understand the financial implications of higher gearing. This isn't usually an entry-level strategy for beginners. * **Property Type and Yield**: High LTV products are more viable if you are investing in properties with strong rental yields. For example, HMOs or multi-unit blocks often generate higher yields than a single-let property. A property generating a gross rental yield of 8-10% might comfortably pass the stress test, even at 75-80% LTV, whereas a property with a 5% yield would struggle significantly. Given that Section 24 no longer allows individual landlords to deduct mortgage interest from rental income for tax purposes, higher yields are even more critical for profitability. * **Capital Appreciation Strategy**: If your primary strategy relies heavily on capital appreciation, high LTV allows you to leverage your capital more effectively. However, this also amplifies risk. What looks like a good deal at 80% LTV might be marginal at 70% LTV. The market for capital appreciation is more volatile and less predictable than rental income, so this approach requires careful analysis of local market trends and economic forecasts. * **Refurbishment Strategy**: If you aim to add value through refurbishment to then refinance at a higher valuation, CHL's 'light refurbishment' or 'heavy refurbishment' products, which often allow for higher LTVs based on the post-refurbishment value, could be very suitable. This ‘flipping’ of the property value allows you to extract capital and recycle it, reducing your overall capital employed in the deal. However, be mindful of renovation costs, which can escalate quickly, and ensure your project adheres to energy efficiency standards, as properties will need a minimum EPC rating of E currently, with proposals for C by 2030. ### Practical Considerations with CHL CHL Mortgages operates exclusively through intermediaries, meaning you'll need to work with a mortgage broker who has access to their product range. A good broker will be invaluable in assessing whether a CHL product fits your criteria, navigating their specific underwriting requirements, and comparing their offering with other specialist lenders. They can also help you understand the nuances of the BTL market, including the impact of the 5% additional dwelling stamp duty surcharge, which significantly increases costs for investors. ### Potential Advantages of CHL's Offerings for Certain Strategies * **Complex Property Types**: CHL is strong in lending for properties that generate higher yields due to their structure, such as **HMOs** and **Multi-Unit Freehold Blocks**. If your strategy involves these, CHL's expertise and product flexibility can be a significant advantage. For example, if you're converting a large family home into a 6-bed HMO, CHL might offer a product that standard lenders wouldn't, effectively allowing you to leverage a higher income stream. * **Experienced Investor Focus**: Their focus on professional landlords means their criteria might be more flexible for those with larger portfolios or more complex income structures, compared to lenders targeting first-time landlords. They understand the intricacies of property business entities. * **Refurbishment Lending**: For strategies involving significant **value-add refurbishments**, CHL offers products that can facilitate the initial purchase and even allow for 'valuation uplift' refinancing quickly after completion, enabling you to extract equity and reuse capital much faster. This can be critical for growing a portfolio with limited initial funds. * **Tailored Solutions**: Rather than generic products, CHL strives to offer more niche solutions for specific high-yield strategies, including **short-term lets** or **holiday lets**. This can provide an avenue for investors looking at diversification beyond traditional long-term rentals, especially if the property is in a tourist hotspot with strong demand. For a seasoned investor leveraging their experience and actively seeking higher yields through these specialist property types, CHL's higher LTV offerings, within their specific parameters, could align well with a growth-oriented strategy. However, for a beginner or an investor seeking simple, standard buy-to-let, the complexities and costs associated with higher LTV specialist products might not be the most appropriate starting point. ## Higher Leverage and Specialist Product Advantages * **Amplified Returns on Capital Employed**: Utilising an 80% LTV, for example, allows you to control a more valuable asset with a smaller cash injection. If a property generating £1,200/month rent with outgoings of £200/month delivers a net profit of £1,000/month, the percentage return on your 20% deposit (£50,000 on a £250,000 property) is significantly higher than if you had put down a 40% deposit. This magnifies your cash-on-cash return, although it also magnifies risk. * **Access to More Properties**: A smaller deposit per property means you can potentially acquire more units or higher value properties within the same capital budget. This is a core strategy for portfolio growth, particularly for those looking to scale up quickly, like myself initially. By leveraging effectively, you can accelerate your progress towards financial goals. For instance, if you have £100,000, you could buy one £250,000 property at 60% LTV (£100k deposit + £150k mortgage) or two £250,000 properties at 80% LTV (£50k deposit each + £200k mortgage each). The latter option, with CHL, could result in double the rental income potential and double the capital appreciation potential, but also double the finance costs and responsibilities. * **Specialist Property Expertise**: For niche assets like HMOs or MUFBs, CHL's underwriting team often possesses a deeper understanding of the specific risks and rewards. This can result in smoother applications and more tailored product offerings compared to generalist lenders who might not fully comprehend the business model. * **Speed and Efficiency**: Specialist lenders can sometimes process complex applications more quickly than mainstream banks, which is crucial in a competitive property market where quick decisions can secure a deal. This is particularly true for refurbishment products where timing is key for project management. ## The Realities and Risks of High LTV BTL Lending * **Increased Vulnerability to Market Downturns**: Higher leverage means smaller equity cushions. A 10% fall in property value on an 80% LTV property wipes out half your equity, whereas on a 50% LTV property, it only takes a fifth. This makes high LTV investments more susceptible to negative equity and puts you at a greater risk if you need to sell in a falling market. * **Higher Interest Costs and Fees**: As mentioned, higher LTV products typically come with a pricing premium. This means more of your rental income goes towards servicing the debt. With mortgage interest not being a deductible expense for individual landlords since April 2020, this directly impacts your net profit and taxable income from your rental venture. For example, if you are a higher rate taxpayer, a £10,000 mortgage interest payment effectively costs you £10,000 from your net rental income, whereas before April 2020 it would have reduced your taxable income by £10,000. * **Stricter Stress Testing**: Lenders mitigate their increased risk on higher LTV products by applying more stringent stress tests. This means the property needs to generate a significantly higher rental yield to qualify for the loan, potentially limiting your property choices or forcing you into areas with higher risk profiles. * **Refinancing Challenges**: If interest rates rise or property values fall, refinancing a high LTV mortgage can become difficult. You might find yourself in negative equity, unable to meet new lender stress tests, or facing hefty early repayment charges if you can't remortgage to a new, more favourable deal. This can trap you in an unfavourable product or force a sale at a loss. * **Deposit Erosion**: If the property value declines, your effective LTV increases, reducing your equity and potentially making future borrowing or refinancing more challenging. This risk is amplified with a larger initial loan percentage. ## Investor Rule of Thumb Never chase the highest LTV just for the sake of it; always base your borrowing decision on a detailed cash flow analysis, a robust contingency plan, and a clear understanding of the full cost of debt over your projected hold period. ## What This Means For You CHL Mortgages offers some compelling products for specific buy-to-let strategies, particularly for those looking to scale or invest in complex property types. However, whether their high LTV options are right for you largely depends on your individual circumstances, risk appetite, and the specifics of your investment. Most landlords don't lose money because they misunderstand LTV; they lose money because they don't fully calculate the impact of higher interest rates, stress tests, and property specific costs like the 5% additional stamp duty charge on a £250,000 property (which is £12,500 on top of the base SDLT) on their net profit.

Steven's Take

Listen, the property market has changed. 'High LTV' isn't a silver bullet, it's a tool, and like any tool, it can be misused. When I started building my £1.5M portfolio with under £20k, I used leverage, absolutely, but it was calculated leverage. CHL offers some great specialist products, especially if you're going for HMOs or refurbishment projects that genuinely add value. But don't just jump at 80% LTV because it's available. You need to scrutinise the interest rate, the stress test, and how it impacts your net cash flow, not just the gross rent. With the base rate at 4.75% and BTL rates up, that extra 5% LTV can make a huge difference to your monthly costs, and with Section 24, those costs hit your bottom line hard. Make sure your strategy can comfortably absorb these costs, especially if you're a higher rate taxpayer. It's about smart growth, not just growth for growth's sake. Get proper advice, understand the numbers inside out, and make sure your deals stack up, even with economic headwinds.

What You Can Do Next

  1. **Engage a Specialist BTL Mortgage Broker**: Work with a broker experienced in CHL's product range and complex BTL cases. They can assess your specific situation, portfolio, and investment strategy against CHL's criteria and those of other specialist lenders.
  2. **Perform Detailed Cash Flow Analysis**: Create a comprehensive spreadsheet that projects your rental income and all expenses (mortgage, insurance, management fees, maintenance, void periods, additional dwelling SDLT, and landlord non-deductible interest) for any potential property. Don't forget to factor in the specific stress test requirements that CHL (or any lender) will apply.
  3. **Understand CHL's Specific Product Criteria**: CHL often has different requirements for HMOs, MUFBs, and standard buy-to-lets. Familiarise yourself with their tenancy requirements, property condition standards, and minimum deposit amounts for the specific product you're considering. Also, check their EPC and energy efficiency requirements.
  4. **Assess Your Risk Tolerance**: High LTV means higher gearing and amplified risk. Honestly evaluate your financial stability, contingency funds, and ability to absorb potential market downturns or interest rate hikes. With current BTL rates between 5.0-6.5%, ensure your projections are conservative.
  5. **Review Your Investment Strategy Against Market Conditions**: Consider whether higher LTV borrowing aligns with current market realities, including interest rates, rental demand, and potential legislative changes like the Renters' Reform Bill. Ensure your strategy accounts for factors like the 5% additional dwelling SDLT, Capital Gains Tax of 18-24% (with a £3,000 annual exempt amount), and Corporation Tax if investing via a limited company.
