The low down on guarantor mortgages

  • What is a guarantor mortgage?

    Guarantor mortgages are a way for a parent or relative to support your mortgage application, by guaranteeing that they will pay the mortgage if you weren't able to. This can help you to increase your buying budget or get you on the ladder if you can't save a deposit.

  • What options are available?

    A guarantor can use their property as security, use their income as support, or use cash savings as security. Our Deposit Boost and Income Boost products are modern twists on these more traditional options.

  • Am I eligible for a guarantor mortgage?

    When applying for a guarantor mortgage, you'll need someone who is willing to help you get on the property ladder (at Tembo we call them a Booster). You and your Booster will also need to pass affordability requirements, as well as both having good credit scores.
