It won't be clear whether you will pass referencing until the referencing process is completed.
Our referencing process is set up to handle a wide range of circumstances including not being resident in the UK, self-employed applicants and housing benefit claimants. As such we can reference tenants regardless of their circumstances, but for obvious reasons we can't say whether you will pass or fail until the full checks are carried out.
Do note, however, that failing referencing doesn't necessarily mean you cannot rent the property. You could still rent the property even if you don't pass referencing.
The most common way to rent a property even when you have failed referencing is to provide a UK-based guarantor who agrees to pay the rent should you fail to pay it in the future. Another solution can be to pay the rent for the let-period upfront, removing the risk that you won't be able to pay for it in monthly installments in the future.
On OpenRent, the landlord decides whether to accept or reject your application. Although most landlords use our referencing service, others have their own process, and in any case may accept an application regardless of the outcome of referencing.
The best thing to do is to contact the landlords of the properties you're interested in, and mention upfront any concerns you have about the application process.
