A growing number of UK landlords are focusing less on expanding their property portfolios and more on strengthening their existing finances, with Foundation announcing the return of its pound-for-pound buy-to-let remortgage product alongside a series of wider pricing improvements.

The specialist lender has reintroduced its F1 Pound-for-Pound Remortgage Only mortgage, aimed specifically at landlords who simply want to replace an existing mortgage rather than borrow additional funds. The move comes as many investors continue to navigate higher borrowing costs, changing tax rules and ongoing economic uncertainty, choosing to improve cash flow and refinance existing lending rather than increase leverage.

For many portfolio landlords, limited company investors and expatriate property owners, refinancing has become an increasingly important financial strategy as fixed-rate mortgages mature over the next two years.

A Different Approach To Buy-to-Let Refinancing

Traditional remortgages often involve landlords releasing additional equity to fund further purchases, renovations or capital expenditure. However, that is not always the objective.

Foundation's relaunched product has been designed for landlords who simply want to move their existing borrowing to a new lender while maintaining the same loan balance.

The two-year fixed-rate mortgage is available at 75% loan-to-value with an initial rate of 3.99% and a 4% product fee. The lender is also offering a free standard valuation and no application fee, helping to reduce the upfront costs associated with refinancing.

While the headline rate is important, one of the more significant aspects of the product lies within the affordability assessment.

Because the mortgage involves no additional borrowing, Foundation assesses affordability using the mortgage pay rate with an Interest Coverage Ratio (ICR) of 125% for all applicants, regardless of whether they are basic-rate or higher-rate taxpayers. This differs from many standard buy-to-let affordability calculations, where higher stress rates can sometimes reduce borrowing capacity.

For landlords whose primary objective is simply replacing an existing mortgage, this approach may provide greater flexibility when refinancing.

Why More Landlords Are Choosing To Stand Still

The buy-to-let market has undergone considerable change over recent years.

Successive increases in interest rates, changes to mortgage interest tax relief, evolving energy efficiency requirements and regulatory reforms have all encouraged many landlords to become more cautious.

Rather than actively expanding portfolios, many investors are concentrating on preserving profitability, managing borrowing costs and maintaining liquidity while monitoring future market conditions.

Industry feedback cited by Foundation suggests that a significant number of landlords are delaying major investment decisions until there is greater clarity around interest rate expectations and the wider economic outlook.

In this environment, products designed purely for refinancing existing debt are becoming increasingly relevant.

Suitable Across A Range Of Landlord Structures

Although individual lending criteria always apply, Foundation's wider buy-to-let proposition supports a broad range of borrower profiles.

Its lending criteria include individual landlords, limited company borrowers, portfolio landlords, first-time landlords, Houses in Multiple Occupation (HMOs), Multi-Unit Freehold Blocks (MUFBs), holiday lets and certain expatriate borrowers through other areas of its product range. The lender also accepts newly established SPVs and does not impose limits on the number or value of properties already mortgaged elsewhere.

This breadth of lending reflects the increasingly diverse nature of today's landlord market, where financing requirements often extend well beyond straightforward single-property investments.

For accountants advising property-owning clients, refinancing existing debt without increasing borrowing may also support broader financial planning, particularly where clients wish to improve cash flow, reduce monthly costs or prepare for future investment opportunities.

Wider Product Transfer Rate Reductions

Alongside the return of the pound-for-pound remortgage, Foundation has also reduced rates across its buy-to-let and residential product transfer ranges by up to 0.25%.

The lender says the changes are intended to strengthen its refinancing proposition while providing brokers with greater flexibility when advising clients approaching the end of their existing fixed-rate deals.

Grant Hendry, Director of Sales at Foundation, said the relaunch reflects current market conditions and the changing priorities of landlords.

He explained that many brokers are seeking practical refinancing solutions for clients who simply want to replace existing borrowing rather than increase their debt, while also benefiting from lower upfront costs and affordability assessments better suited to pound-for-pound remortgages.

Refinancing Decisions Remain Highly Individual

Although specialist remortgage products can offer valuable opportunities, landlords should avoid assuming that switching lenders will always produce the best outcome.

Factors such as early repayment charges, product fees, rental income calculations, tax position, ownership structure and future investment plans can all influence whether refinancing represents good value.

For limited company landlords, portfolio investors and expatriate borrowers in particular, lender criteria can vary considerably, making specialist advice increasingly valuable when comparing available options.



As more fixed-rate mortgages mature throughout 2026 and 2027, products focused on straightforward debt replacement may become an increasingly important part of the buy-to-let lending landscape, particularly for investors whose priority is financial certainty rather than portfolio expansion.
