It has also reduced its two-year discount rates, three and five-year fixed rates and its buy-to-let reversion rates by up to 0.5%.
Other changes to its buy-to-let range include an increase in the maximum portfolio size to five properties and available up to £2m, while the maximum age at the end of the mortgage term will be 85.
Charles Haresnape (pictured), managing director of Aldermore said: “We’re very comfortable with the way our buy-to-let portfolio is performing and feel the time is right to strengthen our range. These enhancements to both criteria and rates will ensure our buy-to-let products are among the most competitive available and I have no doubt they will be popular with both brokers and their clients.”
