Rent Guarantor Explained: Who Can Be One & What They Risk
Last updated: June 2026 · 8 min read
Quick answer
A rent guarantor is someone who legally agrees to pay your rent if you cannot. Landlords ask for one when a tenant has no rental history, a low or irregular income, or is a student. A guarantor is usually a parent or close relative who is a homeowner with a stable income — they typically need to earn around 30 times the monthly rent. The guarantor is liable for the full rent (and sometimes damage) for the entire tenancy, so the role carries real financial risk and should never be agreed to lightly. If you have no guarantor, alternatives include paying rent in advance, a guarantor service, or proof of savings.
For students, first-time renters and anyone with a thin financial history, a guarantor is often the key that unlocks a tenancy. But it is also a serious legal commitment for the person who signs — one that is too often agreed to without reading the small print. This guide explains the role from both sides: what tenants need, and what guarantors are really taking on.
1. Why landlords ask for a guarantor
A guarantor reduces the landlord's risk to almost zero: if the tenant stops paying, someone with proven means is contractually bound to step in. Landlords typically ask for one when a tenant:
- ✓Has no rental history (a first-time renter or recent graduate).
- ✓Is a student without a regular income.
- ✓Earns below the usual income threshold (around 30× the monthly rent).
- ✓Is self-employed or has irregular income that is harder to verify.
- ✓Has recently moved to the country with no local credit footprint.
2. Who can be a guarantor
A guarantor must satisfy the landlord that they could genuinely cover the rent. In practice that means:
- ✓A stable income — commonly around 30 times the monthly rent, sometimes higher.
- ✓Good credit history, checked as part of referencing.
- ✓Often a homeowner, giving the landlord a verifiable asset to rely on.
- ✓Usually based in the same country as the property.
Most guarantors are parents, but a sibling, other relative or close friend who meets the criteria can also act. The relationship matters less than the financial standing.
3. What a guarantor is liable for
This is the part people skip — and regret. A guarantor agreement is a binding legal contract. Before signing, the guarantor should check exactly:
- What is covered — rent only, or also damage, cleaning and legal costs?
- How long — just the fixed term, or does it continue into a rolling periodic tenancy?
- Joint tenancies — in a shared house, am I liable only for my tenant, or for the whole property's rent?
- How to end it — can I withdraw, and under what conditions?
The joint-tenancy point is the most dangerous. In some shared-house agreements, each guarantor can be liable for the entire property's rent — not just their own tenant's share. Always insist the agreement limits liability to your tenant's portion.
4. Renting without a guarantor
No suitable guarantor? You still have options:
- ✓Pay several months' rent in advance — often the simplest substitute.
- ✓Use a paid guarantor service that acts as your guarantor for a fee.
- ✓Provide proof of savings covering many months of rent.
- ✓Show a strong employment contract and salary that clears the income threshold on its own.
- ✓Choose landlords and platforms that accept robust income evidence in place of a guarantor.

Frequently asked questions
What is a guarantor for renting?
A guarantor is a person who signs a legal agreement promising to pay your rent if you fail to. They give the landlord security when a tenant cannot prove a strong rental or income history on their own.
Who can be a guarantor?
Usually a parent or close relative who is a homeowner with a stable income — commonly earning around 30 times the monthly rent. They must pass a credit and income check. Most landlords require a guarantor based in the same country as the property.
What is a guarantor liable for?
Typically the full rent for the entire tenancy, and often the cost of damage too, if you default. Liability can continue if the tenancy rolls into a periodic term, so a guarantor should read exactly what and how long they are agreeing to cover.
Can I rent without a guarantor?
Yes. Alternatives include paying several months' rent in advance, using a paid guarantor service that stands in for a personal guarantor, providing proof of savings, or renting from landlords who accept strong income or employment evidence instead.
Does a guarantor need to be a homeowner?
Not always, but many landlords prefer it because a homeowner has a verifiable asset. A guarantor who rents can sometimes be accepted if their income is high enough and their credit is strong.
