Bank of Ireland has introduced Joint Borrower Sole Proprietor (JBSP) options specifically designed for remortgage customers. This move enables a wider range of borrowers to access mortgage solutions that cater to diverse family structures and financial situations.

What are the new JBSP options for remortgages?

The new JBSP options allow borrowers to combine incomes while only one person holds the property title. This is particularly advantageous for those who may have lower individual incomes but can benefit from a combined application. Additionally, the maximum loan amount has been increased to £1.5 million, expanding the potential for larger remortgage amounts.

Who can benefit from these remortgage changes?

The changes are aimed at a broad audience, including first-time buyers, young professionals, and families looking to remortgage. The minimum age for the main applicant has been set at 18, and in certain situations, students may also qualify, making homeownership more accessible to younger individuals.

What this means for borrowers seeking remortgages

For borrowers, the introduction of JBSP options signifies a shift towards more inclusive lending practices. It acknowledges the realities of modern family life and the diverse paths to homeownership. With increased loan limits and the consideration of students, more individuals can now explore remortgaging opportunities that were previously out of reach.
