This includes an increase in its maximum BTL mortgage term to 40 years, up from the previous 35-year limit.

The Nottingham says the shift has been built to provide landlords with more flexibility when structuring borrowing, while also supporting a growing number of accidental landlords where longer terms can help manage affordability and repayment profiles.

In addition, the society has refreshed its BTL criteria to support affordability and access.

The refresh includes opening lending to first time landlord borrowers, enabling customers entering the rental market for the first time to build sustainable investments, as well as introducing more flexible lease length requirements where properties continue to meet the society’s minimum end of term standards.

It has also refreshed its approach to portfolio coverage, which it says is part of a broader effort to support more consistent and transparent assessments of background portfolios, while maintaining its core BTL affordability framework and responsible lending standards.

Nottingham Building Society sales director Matt Kingston says: “The buy-to-let market continues to evolve, and landlords are operating in a very different environment to even a few years ago.”

“Borrowing structures, portfolio management, and the types of customers entering the market are all changing.”

“These updates are about recognising that reality and giving brokers more flexibility when placing cases.”

“Extending the maximum mortgage term, opening our criteria to first-time landlord borrowers, and adopting a more transparent portfolio stress rate all help create a more practical framework for landlords managing their investments today.”
