Buckinghamshire Building Society increases Expat BTL maximum LTV to 80% and launches new two-year fixed rates

05 March 2026

Buckinghamshire Building Society has increased the maximum loan-to-value (LTV) on its Expat Buy to Let products from 75% to 80%, while also launching two new fixed rate options for both personal and limited company applicants.

The changes are designed to give brokers greater flexibility when supporting expat landlords looking to invest in the UK property market, particularly those seeking higher leverage in a competitive environment.

The new product options both offer a fixed rate until 31/05/2028 and are available for personal and limited company (SPV) applicants as follows:

Everyday Expat BTL – 5.79%
Expat BTL Ltd Co SPV – 5.89%

Both products provide short- to medium-term rate certainty, giving landlords clarity over repayments while retaining the benefit of a manually underwritten approach.

Enhanced Criteria for Flats and Apartments

In addition to the LTV increase and new product launches, the Society has also recently enhanced its property criteria.

Buckinghamshire Building Society will now consider flats and apartments in blocks of up to 10 storeys, increased from the previous limit of six storeys. This broadens the scope for landlords targeting city-centre and higher-density locations.

For ex-local authority properties, the maximum remains at four storeys, reflecting the Society’s considered and responsible approach to risk.

All cases continue to be manually underwritten, ensuring that property type, applicant profile and overall affordability are assessed on their individual merits.

Claire Askham, Head of Mortgage Sales at Buckinghamshire Building Society, said:

“Expat landlords are a key part of the UK investment landscape, but they don’t always fit neatly into high street criteria – particularly when it comes to higher LTVs. By increasing our maximum LTV to 80% and expanding our appetite for flats in taller blocks, we’re giving brokers more scope to place cases that might otherwise stall.

“As always, we take a common-sense, case-by-case approach. Our manual underwriting means we can look beyond the headline details and work with brokers to find solutions that are right for their clients.”

The enhancements reflect the Society’s ongoing commitment to supporting intermediaries with specialist solutions, responsive service and accessible decision-makers.
