Quick answer: A cosigner or guarantor is another party — either someone you know or a third-party insurance company you pay — who becomes legally tied to your lease. OneApp Approval Assist is different. It helps you get approved on your own, for a fixed, one-time fee when you apply at a participating property (see nationwide list of OneApp properties here).

When Approval Requires A Little Help: Understanding Your Options
Getting denied for an apartment is stressful, and it’s easy to feel like you’re out of options. The good news is you’re not.
Below, we break down what your options are and the pros and cons of each, so you can decide what fits your situation.
Key Takeaways
- When a renter needs help to get approved, they can ask another party to act as a “cosigner” or “lease guarantor” that will pay their rent if they can’t.
- Cosigners and lease guarantors are often used interchangeably with one key difference: a cosigner actually signs the lease and access to the property. A guarantor does not.
- Some people will pay an insurance company to be their cosigner or lease guarantor, with a fee set based on things like credit and income, and penalties that could apply down the line.
- OneApp Approval Assist is different. You pay one flat fee upfront, with payment plans available at most properties. And there’s no extra bill later if something goes wrong.
Option 1 | Someone You Know: A Personal Cosigner or Guarantor
A personal cosigner or guarantor is someone in your life, usually a parent or close friend, who agrees to cover your rent if you can’t pay.
Although often used interchangeably, these terms differ in one important way: a “cosigner” actually signs the lease and has access to the property. A “guarantor” does not.
To use this option, you need:
- Someone who says yes
- That person to have good credit and steady income
- A relationship where asking feels okay
This option is free. But it only works if you have someone willing and able to help, and it puts their credit at risk if payments are missed.
Pros of a Personal Cosigner or Guarantor
✅ No cost involved
✅ Keeps things simple, no company or fees involved
Cons of Personal Cosigner or Guarantor
❌ Puts their credit at risk if you fall behind
❌ Requires an ask that can feel uncomfortable
❌ Not everyone has someone available who qualifies
❌ May cause delays due to the paperwork involved
Option 2 | An Insurance Company You Pay: A Cosigner or Guarantor for Hire
Instead of asking a person in your life, you can pay an insurance company to act as your cosigner or lease guarantor. It’s the same job, just done by a business instead of someone you know, and for a fee.
These companies may call themselves a guarantor service or a cosigning service, but most work the same way.
How it works: The company reviews your credit, income, and rental history, then agrees to cover your rent if you default
Pricing: Assess risk as insurance, usually based on your credit score and income, calculated per renter rather than one flat rate
When you learn the price: Usually after your credit and income have been reviewed
What’s covered: Varies by insurance provider and plan. Some cover rent only, others include damage and legal fees as an add-on
If they pay a claim: That amount is usually billed back to you
Approval speed: Usually fast, often the same day
Pros of a Cosigner or Guarantor for Hire
✅ No need to ask someone personally
✅ Often approved the same day
Cons of a Cosigner or Guarantor for Hire
❌ Price often isn’t confirmed until after you apply, and can be expensive
❌ You may owe money back if the company ever pays a claim on your behalf
❌ Coverage may not include everything, damage or legal fees can cost extra
Option 3 | OneApp Approval Assist
OneApp works differently. You don’t need a cosigner or guarantor.
How it works: You apply at the OneApp partner property. They then refer you directly to OneApp Approval Assist where you can apply for support. If approved (and most are), OneApp backs your lease so the property can approve you without a cosigner or guarantor.
Pricing: One flat fee equal to one month’s rent*, no matter your credit profile.
When you learn the price: Before you apply for support. And if it doesn’t work out, your fee is refunded back to you.
What’s supported: We cover a large portion of debt owed to the property manager that the renter may incur if the lease defaults (through eviction, lease termination, or other issues).
Credit check: Soft pull only, so it doesn’t affect your score.
If something goes wrong: The reimbursement paid to your landlord isn’t billed back to you.
Approval speed: Within minutes.
*For leases longer than 13 months, the fee will be prorated to account for the longer term of coverage.
Pros of OneApp Approval Assist
✅ Flat fee, known upfront, no surprises
✅ No cosigner or guarantor needed
✅ Payment plans available
✅ No debt owed back if something goes wrong later
✅ Approval within minutes
Cons of OneApp Approval Assist
❌ Only available at partner properties nationwide, so it’s worth checking if your building participates.

FAQs About Multifamily Approval Optimization
Is a cosigner the same as a guarantor?
Almost, but there’s a small difference. A cosigner signs the lease and shares responsibility right away, and can even live in the unit. A guarantor doesn’t sign as a tenant and usually only has to pay if you fall behind. Even so, most people use the two words to mean the same thing, and either one can be a person you know or a company you pay.
Will OneApp hurt my credit?
No. We only run a soft credit check, which doesn’t affect your score.
Can approval optimization actually reduce bad debt?
Yes, when it’s structured correctly. By expanding approvals within defined risk parameters and with appropriate offset mechanisms in place, operators can increase occupancy while maintaining, or even improving, collection performance.
Why don’t some companies tell me the price right away?
Because, for insurance models, your price depends on your credit and income. They can’t calculate it until they check those first which may lead to extra costs on your end.
Do I have to pay every year for OneApp?
No. One fee covers your full lease, up to 24 months. In some cases, a property may ask for a renewal fee, which is half your original amount.
What if I can’t pay the full fee at once?
You can either pay in full upfront with no additional fees, or opt into a payment plan at select properties. Learn more about the fee and payment plan options here.
