Role and Responsibilities of a Guarantor

A guarantor will step in and fulfill the lease obligations if the tenant fails to do so. By acting as security, the guarantor reduces the landlord’s risk and improves the probability of the lease terms being met. Once added to a lease, the guarantor will be responsible for the following if the tenant defaults:

  • Paying Rent – Guarantors must ensure that rent is paid in its entirety and on time if the tenant neglects this responsibility.
  • Damages – If the tenant damages the rental unit and doesn’t fix the issue, the guarantor will be liable for covering the expenses.
  • Legal Disputes – If the landlord files a lawsuit against the tenant due to lease violations, and the tenant is unable to cover the related costs or penalties, the guarantor may be pursued for payment.
