Product Transfers vs Remortgages – Which Is Better for Landlords?

When a buy-to-let mortgage deal comes to an end, landlords face a key decision: should they do a product transfer with their current lender, or a full remortgage to another lender? Both options have advantages and drawbacks. In 2026, with affordability tests still challenging and rates shifting, understanding the trade-offs can save landlords time, money and stress.

What Is a Product Transfer?

A product transfer is when you stay with your existing lender but switch to a new rate once your current deal expires. It usually involves minimal paperwork, no valuation, and no legal process. Many lenders also waive arrangement fees on transfers.

Pros:

• Quick and simple process.
• Usually no legal or valuation costs.
• No affordability reassessment in many cases.

Cons:

• Fewer product choices compared with remortgaging.
• Limited ability to release equity.
• Rates may not be the most competitive in the wider market.

What Is a Remortgage?

A remortgage is when you switch to a new lender and take out a brand-new mortgage. This may allow access to better rates, higher loan-to-value (LTV) options, or equity release for portfolio growth. However, it involves a full application, affordability testing, valuation and legal work.

Pros:

• Access to the full market of lenders and products.
• Opportunity to release equity for new purchases or refurbishments.
• Potentially lower rates if another lender is more competitive.

Cons:

• Full affordability checks and underwriting.
• Valuation and legal processes can add time and cost.
• Arrangement fees may be higher than transfers.

Case Study: Transfer vs Remortgage

Scenario: A landlord’s two-year fix ended in December 2025. The lender offered a product transfer at 5.75%. Another lender offered 5.25% on a remortgage, but with a £2,000 fee.

Outcome: The landlord had a £150,000 loan. The 0.5% lower rate saved £750 annually. Over two years, savings totalled £1,500, less than the £2,000 fee. The product transfer was cheaper overall.

However, had the landlord wanted to release equity for another purchase, the remortgage would have been the better option despite higher upfront cost.

When a Product Transfer Makes Sense

• You want speed and simplicity.
• You do not need to release equity.
• Your current lender’s offer is close to market best rates.
• You want to avoid fresh affordability checks.

When a Remortgage Makes Sense

• You want to release equity for expansion or refurbishments.
• You want access to a wider choice of products.
• Your current lender’s rates are uncompetitive.
• You want to move borrowing into a limited company structure.

Practical Tips for Landlords in 2026

• Review both product transfer and remortgage options 6–12 months before expiry.
• Calculate total costs, not just headline rates, including fees.
• Model cashflow under both scenarios to see long-term impact.
• For portfolios, consider sequencing – some properties may be best remortgaged, others simply transferred.

Final Thoughts

There is no one-size-fits-all answer. Product transfers are efficient and low-cost, while remortgages offer flexibility and opportunity. The best choice depends on your strategy: stability vs growth, simplicity vs maximum savings. The key is to compare both routes before making a decision.
