“Soaring borrowing costs will cause pain to landlords this year, as they join millions of consumers facing higher mortgage repayments,” said Rachel Springall (pictured right), finance expert at Moneyfactscompare.co.uk. “This is terrible news, as rising costs could lead to higher rental payments for tenants, or a drop in the pool of properties available for rent if landlords decide enough is enough and sell off their portfolio.
“The unrest in the Middle East has caused absolute mayhem in the residential mortgage market, buy-to-let rates are also being hiked, and hundreds of deals have been pulled from sale.
“The positive sentiment entering 2026 has been shattered, and landlords not only have to face higher borrowing costs, but also prepare themselves for the Renters’ Rights Act, which comes into effect at the start of May 2026.”
Springall also noted that landlords might need extra borrowing to fund refurbishments and energy-efficiency upgrades to meet the Decent Homes Standard and EPC requirements.
