Broker support remains essential for landlords, who typically hold 6.5 buy-to-let loans, spread across an average of 2.1 lender relationships and with average total borrowing standing at £714,000, according to new data from Pegasus Insight.

The research found that the majority continue to rely on intermediaries when arranging buy-to-let finance. This is particularly the case for landlords with larger portfolios or more complex borrowing structures.

The Landlord Trends Q4 2025 shows that the multi-loan, multi-lender approach highlights the operational complexity involved in managing property finance. It means that, rather than a single mortgage product, many landlords are juggling multiple borrowing arrangements, with the added complexity of different terms, maturities and refinancing timelines.

But the data also shows that landlords seem to be on top of managing the complexity they face and are highly engaged with financing decisions. Seven in ten began their most recent remortgage process at least three months ahead of product maturity.

Mark Long, managing director and founder of Pegasus Insight, said: “What stands out from the data is the degree to which landlord borrowing is structured across multiple products and lenders. For many, managing finance is no longer a one-off decision, but an ongoing process.”

A significant shift in operations

This marks a significant shift in how the sector operates and is in stark contrast to the past, said Long.

“What’s interesting here is not just the number of loans, but what that says about how landlords are operating. Managing multiple mortgages across different lenders requires a level of coordination and forward planning that simply wasn’t part of the model for many landlords historically.

“That creates both opportunity and exposure for borrowers. When financing is structured across several products, decisions in one part of the portfolio can have knock-on effects elsewhere, particularly around refinancing and cashflow timing.”

And it’s in this management of multiple products that brokers can be particularly useful, he said.

“It reinforces the importance of professional mortgage advice. As portfolios become more layered, landlords need a clear view across their borrowing, rather than treating each mortgage in isolation.”
