By acting as a guarantor, you are making a financial commitment that you would take on the responsibilities of the tenancy if the tenant you are acting for should fail to meet them. For example, you would be called on to pay any missed rent payments if the tenant can’t or won’t do it themselves. As such the letting agent needs to be sure you could afford to cover the rent if this should happen, and so we need to carry out reference checks to verify a guarantor’s income too.
