The nation's landlords are finding renewed optimism, thanks to increased stability in the mortgage market and a notable drop in buy-to-let (BTL) mortgage rates, according to a detailed analysis by Octane Capital.

Octane Capital closely examined how the average monthly cost of a BTL mortgage has shifted since the Bank of England began hiking interest rates in December 2021. Their review spans key moments: from the rate surge at the end of 2021, to the rate hold in September of last year, and finally, the significant rate cut in August 2023—the first cut in four years.

Back in December 2021, when the interest rate hikes first took hold, BTL mortgage holders saw a modest average rate of 1.70%. This translated to a manageable monthly interest-only repayment of £286, but a full repayment plan would stretch the budget further to £827 each month.

Fast forward to September 2023, after 14 consecutive rate hikes, with the base rate peaking at 5.25%. The average landlord suddenly found themselves staring at a much steeper financial commitment.

Octane's findings show that by this point, the average BTL mortgage rate had surged to 5.99%, and monthly repayments for those making full payments had soared to £1,382—marking a jaw-dropping 67% increase. Landlords opting for interest-only payments were hit even harder, with monthly costs skyrocketing by 274%, landing at £1,071.

However, since September 2023, the tides began to turn. The decision to hold the base rate brought some much-needed stability to the mortgage sector. And with the first interest rate cut in years arriving in August, the cost of borrowing for landlords has seen a noticeable dip.

As of August 2024, the average BTL mortgage rate has eased down to 4.33%, offering landlords some breathing room. Full monthly repayments have decreased by 12%, now averaging £1,212, while interest-only payments have dropped by a significant 25%, down to £801.

Amidst continued speculation about landlords fleeing the market, new data from Pegasus Insight paints a different picture. Those landlords who remain in the game are standing firm, and many are expanding their portfolios with renewed confidence.

During the second quarter of 2024, the average portfolio size of a BTL landlord ticked up from 7.2 properties to 7.6. In the East Midlands, the increase was especially striking, with landlords adding an average of 2.5 properties to their portfolios between Q1 and Q2. Growth was also seen across Wales (+1.9), the North West (+1.0), the East of England (+0.5), and the South East (+0.5).

Jonathan Samuels, CEO of Octane Capital, remarked: “Our new Labour Government has shown early signs of intent with respect to rental market reforms, the majority of which are seemingly designed to further deter investment within the buy-to-let sector.

"Despite this, those intent on remaining within the sector are doing so with confidence, with landlords across the nation bolstering their portfolio sizes so far this year.

“This confidence has come following the greater degree of mortgage market certainty that has materialised following a hold on interest rates and, as a result, landlords are benefiting from reduced monthly mortgage costs.”

While challenges remain, the landscape for landlords is certainly shifting. The combination of falling rates and stabilized policy signals is breathing new life into the market, and those willing to stay are finding reasons to grow.
