In this situation, as a guarantor, you are likely to be responsible for whatever any of the joint tenants owe the landlord, not just what the tenant you are helping may owe. You may also be responsible for any damage caused by other tenants, not just the one you're wanting to help.
Your Liability as a Guarantor If they fail to meet their obligations, creditors can pursue you directly for the debt. This can lead to lawsuits, credit damage, and financial loss, all because you agreed to help someone out.
Typically, a Guarantor Agreement is appended to the end of a lease agreement as an addendum. If, for whatever reason, you need to add a guarantor to a lease that has already been signed, be sure to have all tenants sign the agreement as well as the guarantor.
How to write a Texas lease agreement Begin by including the names and contact information of both the landlord and tenant. Describe the rental property, including its address and any unique features. Specify the lease term, including the move-in and move-out dates.
It will still be hard because guarantors are usually for students, and most landlords will expect working tenants to make 2.5 to 3 times the rent as you say, but you'll have a better chance than if you don't go into the details of your situation.
If a prospective renter doesn't meet those criteria, they should consider finding a guarantor who has a credit score of 700 or higher and an annual income of at least 80 times the monthly rent. For example, if the rent is $2,000 a month, the guarantor would need to make at least $160,000 a year.
No rental history: Many landlords or property managers require first-time tenants to have a guarantor. Once you've built up your rental history, you can possibly lease elsewhere without a personal guarantor.
Financial Requirements Income: Guarantors need to have a much higher income than what is needed for the tenant to qualify. This is usually about 80-100 times the monthly rent. For example, if the rent is $1,500 a month, the guarantor might need to earn at least $120,000 a year.
In most cases, guarantors will fill out the same application as a full lessee. The difference being that some landlords require only a credit screening and not the full criminal + eviction history check for the guarantor.
