How to Screen Co-signers and Guarantors

A co-signer (or guarantor) agrees to pay the rent if the tenant fails to do so. This is common for students or first-time renters.

1. Higher Standards

The co-signer needs to support their own household plus your tenant's rent.

• Income: Look for 4x-5x the monthly rent in income.
• Credit: Excellent credit (700+) is a must.

2. Full Application

The co-signer must fill out a full application. Verify their income and run their credit just like a tenant.

3. The Agreement

They must sign a "Guaranty of Lease" document. Ensure it states they are "jointly and severally liable" for all financial obligations, including damages, not just rent.

4. Out-of-State Risks

Be cautious with out-of-state co-signers. It is much harder to sue and collect from someone in a different jurisdiction.

Conclusion

A strong co-signer significantly reduces your risk, but only if they actually have the means to pay.
