Which mortgage products or lenders are most popular with UK buy to let investors right now?
Quick Answer
Fixed-rate buy-to-let mortgages from specialist lenders and challenger banks are most popular with UK investors due to current market stability needs and tailored product offerings.
## Securing Your Investment: Popular Buy-to-Let Mortgage Choices
When it comes to financing a buy-to-let (BTL) property in the UK, investors are primarily looking for stability, competitive rates, and products that align with their investment goals. Right now, fixed-rate mortgages are the clear front-runner for most landlords.
* **Fixed-Rate Mortgages (2-year & 5-year):** These remain incredibly popular, offering payment certainty amidst fluctuating interest rates. While the Bank of England base rate sits at 4.75%, BTL mortgage rates typically range from 5.0-6.5% for 2-year fixes and 5.5-6.0% for 5-year fixes. Locking in a rate for a set period allows landlords to budget efficiently, which is especially important for cash flow.
* **Interest-Only Mortgages:** Most BTL mortgages are structured as interest-only. This keeps monthly repayments lower, maximising rental profit and freeing up capital for further investments or property maintenance. The principal loan amount is usually repaid when the property is sold or by other means.
* **Product Transfers:** Many landlords prioritise staying with their existing lender when their fixed term ends, opting for a product transfer. This is often simpler, quicker, and can sometimes avoid new valuation or legal fees, proving a popular choice for refinancing without major upheaval.
* **HMO Mortgages:** For investors targeting higher yields through Houses in Multiple Occupation (HMOs), specialist lenders offer specific HMO products. These are designed to accommodate the unique licensing and rental income calculations associated with multi-let properties. For example, a 5-bed HMO might generate £500 per room per month, leading to a higher overall income than a single family let, which lenders then use for their affordability calculations.
* **Limited Company Mortgages:** With Section 24 impacting individual landlords (mortgage interest is no longer deductible for personal income tax calculations), more investors are opting to incorporate. Limited company mortgages are specifically designed for properties held within a company structure. Corporation tax is 19% for profits under £50k, making it an attractive option for some.
## Navigating the Buy-to-Let Lending Landscape: What to Watch Out For
While the BTL market offers opportunities, there are specific challenges and pitfalls that investors should be aware of, especially with current economic conditions.
* **Rising Interest Rates:** The current interest rate environment means that products are significantly more expensive than a few years ago. Higher rates mean higher repayments, directly impacting your cash flow and potential profit margins. For instance, at a 5.5% notional rate, a standard BTL stress test requires 125% rental coverage, which means rental income needs to be substantial to secure financing.
* **Increased Stress Tests:** Lenders are applying stricter affordability checks. The typical BTL stress test requires rent to cover 125% of the mortgage payment calculated at a notional rate, often around 5.5%. This means your property's rental income needs to be robust to meet lender criteria, impacting how much you can borrow or if you can borrow at all. Investors should always calculate their rental yield to ensure it meets these requirements.
* **The Impact of Section 24:** Individual landlords can no longer deduct mortgage interest from their rental income before calculating tax, which has significantly reduced profitability for many. While corporate vehicles like limited companies can still deduct interest, investors need to understand the tax implications thoroughly.
* **Mortgage Broker Importance:** The BTL market is diverse and complex. Relying on an experienced mortgage broker is crucial. They have access to specialist lenders and products not available on the high street and can guide you through the intricate criteria, saving you significant time and potential rejections. Avoid trying to navigate this alone if you're not an expert.
* **Lender Specificity:** High street banks often have very conservative lending criteria for BTL compared to specialist lenders. They might require higher deposits or have stricter rental coverage ratios. For example, a high street bank might only lend on standard family lets, whereas a specialist lender will cater to HMOs or multi-unit freeholds.
## Investor Rule of Thumb
Always secure your financing before committing to a property; the deal isn't a deal until the money is in place and the lender has given you an offer.
## What This Means For You
Understanding the popular mortgage products and the lending landscape is fundamental to building a robust property portfolio. Most landlords don't lose money because they choose the wrong product, they lose money because they choose the wrong product for their specific strategy without understanding the long-term implications.

Steven's Take
The buy-to-let mortgage market is dynamic and heavily influenced by the Bank of England's base rate. My advice is always to fix your rates where possible, especially with the current market volatility. Don't be afraid of the specialist lenders; they often have the most flexible products for different investing strategies, whether you're targeting an HMO or a multi-unit freehold. Work with a good broker, it's not an expense, it's an investment in getting the right deal.
What You Can Do Next
Assess your investment strategy (e.g., standard buy-to-let, HMO, commercial) to determine the most suitable mortgage product type.
Engage a specialist buy-to-let mortgage broker who has access to the full range of lenders, including those not on the high street.
Calculate your potential rental yield and cash flow using current BTL interest rates (5.0-6.5%) and the 125% stress test, ensuring the property meets lender affordability criteria.
Consider the tax implications of individual vs. limited company ownership, especially in light of Section 24's impact on mortgage interest deductibility.
