Remortgaging Landlords Dominate Buy-to-Let Market Activity

Remortgaging landlords are generating the majority of lenders’ business in the buy-to-let (BTL) sector, according to new research. A survey found that 57% of leveraged landlords arranged a refinancing deal in the last 12 months, a figure up 10 percentage points on the previous quarter.

The findings come from the latest Landlord Trends research by Pegasus Insight. The 57% figure matches the high first recorded at the end of 2025. The research also shows that two-thirds of landlords arranged their most recent BTL loan through a mortgage intermediary, with this rising to three-quarters among portfolio landlords.

When selecting a mortgage, landlords placed the greatest importance on securing a competitive interest rate, followed by low upfront fees and charges. Remortgages and product transfers together accounted for around eight in ten recent transactions, while mortgages for new purchases made up just 8%.

Fixed Rate Expiries Fuel Activity

The report highlights that landlords coming to the end of fixed rate deals are a key driver of current activity. In the last two years, 62% of mortgaged landlords have reached the end of a fixed rate period. Of these, 60% remortgaged with their existing lender, while 29% switched to a different lender. Nearly a third of maturing business therefore changed hands.

Most landlords (64%) began arranging their replacement deal three to six months before their fixed rate ended. The most commonly cited challenges at renewal were higher interest rates and difficulty finding a competitive deal.

Looking ahead, 40% of borrowers plan to remortgage or take a product transfer in the next 12 months, covering an average of two-and-a-half loans each. Among portfolio landlords with four or more BTL mortgages, around half expect to refinance in the coming year, across an average of 3.7 loans.

These trends are relevant for UK letting agents and inventory clerks, as ongoing refinancing activity may impact landlord decision-making, property management timelines, and the volume of tenancies under management.
