A poll of 500 landlords by Butterfield Mortgages asked them to name three qualities that they value most when choosing a buy-to-let broker.

It found that “tax and regulatory expertise” was the most highly-prized quality with 38% of respondents naming this, followed by “’access to a wide range of flexible, bespoke, or specialist financial solutions”, which was selected by 36% of landlords and “access to exclusive products not available directly to borrowers”, selected by 34%.

Less important broker qualities, which were selected by fewer than 30% of landlords included “clients of similar demographics”, “a broad range of lender partnerships”and “expertise in the local property market”.

Butterfield chief executive Alpa Bhakta says: “This research comes at a pivotal time, with Rachel Reeves’s Budget still fresh in people’s minds. Indeed, it is noteworthy that expertise in tax and regulation ranked higher than product range, highlighting the ongoing uncertainty among landlords about the potential impact of government policies on the buy-to-let market.

“Evidently, brokers and lenders must focus on providing access to up-to-date, expert guidance to help landlords navigate these challenges effectively.

“Our research also reveals that, despite recent rate cuts, borrowers still rely on brokers to offer a diverse range of financial options that enable them to adapt confidently to the evolving buy-to-let market.

“What’s more, landlords expect brokers to deliver a personal, tailored service that caters to their specific needs. The survey underscores the value landlords place on quality, human-centred service.

“Lenders must also consider these findings carefully – and they need to recognise their role in supporting both brokers and their clients as well.”
