West One has announced an expansion of its residential mortgage and second charge product ranges, enhancing options for borrowers and brokers alike. The updates include larger maximum loan sizes, improved automated valuation model (AVM) criteria, and the introduction of additional credit tiers, which can significantly impact the mortgage market.

What changes has West One made to its mortgage offerings?

West One has introduced a new prime credit tier for residential mortgages, allowing lending up to 90% LTV. This tier is available to first-time buyers, home movers, and those looking to remortgage, with loan-to-income (LTI) multiples of up to 6.5x. Additionally, maximum loan sizes for its extra residential range have been raised to £1 million at 85% LTV in the premier extra and platinum extra product tiers. The AVM criteria have also been enhanced, facilitating purchases and remortgages up to 85% LTV.

How does this affect borrowers and brokers?

The increased loan sizes and updated credit criteria are designed to remove barriers for borrowers, allowing more individuals to access West One’s Extra product ranges. This is particularly beneficial for those who may have experienced isolated financial issues, as the new criteria acknowledge that these should not define an otherwise strong borrower. For brokers, the expanded offerings provide greater flexibility in meeting client needs.

What this means for the mortgage market

The enhancements by West One signal a shift towards accommodating more borrowers in the mortgage market. With larger loan sizes and higher LTVs, more clients can benefit from competitive mortgage options. This could lead to increased activity in the housing market, particularly among first-time buyers and those seeking to remortgage.
