What is often required for a guarantor to agree to the role?

A guarantor typically needs to prove sufficient income to cover the lease to ensure that they have the financial capability to support the tenant in fulfilling their obligations. This requirement serves as a safety measure for landlords, as it indicates that the guarantor is financially stable and capable of stepping in if the tenant fails to pay rent or meet other lease obligations. By providing proof of income, such as pay stubs, tax returns, or bank statements, the guarantor demonstrates their reliability and commitment to covering any potential financial shortfalls from the tenant. This aspect is crucial in the leasing process, as it offers landlords reassurance that there is a backup plan in place for securing rent payments.

In contrast, the other options do not typically reflect the standard expectations of a guarantor's role. A nominal fee or a formal interview may not be universally required, and co-signing without financial backing undermines the purpose of having a guarantor, as it reduces the landlord's security against non-payment.
