Institutional lease guarantors: how they work and what they cost

An institutional guarantor is a company that guarantees your lease in place of a parent or friend, for a one-time fee that usually runs from under half to slightly more than one month’s rent. You pay it before you sign, the landlord gets the protection, and if you stop paying, the company pays the landlord and then comes to you for the money.

These services exist because many NYC landlords want a guarantor earning about 80 times the monthly rent (see guarantor requirements), and plenty of renters don’t have one: international students, people who just moved to the US, freelancers, and anyone whose family lives outside the tri-state area.

How an institutional guarantor works

1. 1

   Check the building accepts one

   Coverage only works where the landlord has agreed to take that provider. Ask the leasing office which companies it accepts before you apply.
2. 2

   Apply online

   You share income, assets and, if you have it, US credit. Some providers ask a parent or relative abroad to qualify as a “responsible party.”
3. 3

   Get a quote

   The price depends on your rent, lease length, credit and the coverage the landlord requires.
4. 4

   Pay the fee

   Usually in full and up front, before lease signing. It is separate from first month’s rent and the security deposit.
5. 5

   Landlord receives the guaranty

   The company, or the insurer behind it, now backs your lease for the term. At renewal the landlord may require a new policy and a new fee.

What it costs

Most providers price the guaranty as a percentage of one month’s rent for a 12-month lease. The figures below come from each company’s own pages as of October 2026. They are examples, not endorsements, and prices change, so get your own quote.

For a $3,000 apartment, a fee of 70% to 110% of rent works out to $2,100 to $3,300 before you have paid any rent. Longer leases cost more. Insurent publishes how much more each lease length costs compared with a one-year guaranty; the table applies those markups to a $3,000 rent at its 70% to 90% range for US renters.

Add the fee to your move-in budget with the move-in cost calculator. If you have roommates, ask how the policy is priced: Insurent says it considers combined income and each person signing the lease must apply, and Leap says its fee is charged per lease so co-applicants can share it.

Who qualifies

Institutional guarantors still screen you, just with lower bars than a landlord’s 40x. Insurent, for example, publishes these tests: yearly income of at least 27.5 times the monthly rent, or liquid assets of at least 50 times the rent, plus “decent to good” credit for US renters. Renters with very poor credit are not eligible. International students qualify through a responsible party, typically a parent, who earns at least 50 times the monthly rent in their home country or holds liquid assets of 80 times the rent. Other companies don’t publish fixed thresholds and decide on each application.

What happens if you don’t pay

This is the part renters most often misunderstand. The guaranty protects the landlord, not you. TheGuarantors states that if you leave an unpaid balance, it pays the landlord’s claim and you are then responsible for reimbursing it. Insurent says a renter who defaults faces legal action to recover what the insurer paid, plus legal fees, and that the default will hurt your credit. Your lease obligations don’t change, and the landlord can still bring an eviction case.

Institutional guarantor vs the alternatives

Paying months up front. New York caps any deposit or advance at one month’s rent, and the Attorney General says a landlord can’t charge last month’s rent in advance on top of a security deposit. The state housing agency says an owner can’t require extra security from a tenant, a guarantor or any third party. Whether a tenant may volunteer prepaid rent is not clearly addressed, so don’t treat it as a standard option.

Deposit alternatives are different. Some of the same companies sell security deposit replacement products. TheGuarantors, for example, describes Deposit Coverage as a non-refundable fee of usually 25% to 50% of a month’s rent that reduces the cash deposit. Unlike a deposit, you never get that fee back, and you can still owe for damage.

Before you pay, check

• The landlord has confirmed in writing that it accepts this provider.
• The quote covers your full lease term, and what a renewal will cost.
• The refund policy if the landlord rejects you or the lease is cancelled before move-in.
• Whether co-applicants can share one policy and one fee.
• What you owe the company if a claim is paid, including legal fees.
