Struggling to stretch your income to buy a home? 🏠🔑
In today’s market, property prices mean your income doesn't always match the borrowing amount you need.
An Affordability Booster Mortgage (officially known as a Joint Borrower Sole Proprietor mortgage) is one option available to help bridge that financial gap.
How it works:
Combined Income: A close relative links their earnings to your mortgage application, which can increase the overall amount you are able to borrow.
Sole Ownership: They act as a joint borrower and share responsibility for the mortgage payments, but they are not named on the property deeds. You remain the sole owner of the home.
Tax Efficiency: Because your family member is not added to the property deeds, it avoids triggering expensive second-home stamp duty taxes for them, while preserving any tax relief or buyer status you hold.
Weighing it up:
While this structure helps some buyers secure a property, it is not suitable for everyone. There are significant financial and legal pros and cons to consider for both you and your family member before making a decision.
Every financial situation is different and each provider has their own lending criteria.
