Providing proofs

Tip:

You should submit copies or scans of the original documents. Photos are acceptable, but you must submit them as a PDF, TIF or a JPEG. We don't accept mobile phone banking screenshots. If the submitted documents show a 16 digit PAN, please redact this information.

Please don’t submit proofs we haven’t asked for, as this may delay the progress of your case.

When applying for a mortgage with us, we may ask to see some proofs to help us confirm your clients' information such as:

Your clients' name and address
How much they earn
Proof of their deposit

You can provide these proofs on NFI Online (opens in a new window) once you’ve submitted your client’s application, and they've been requested. To speed up your application, make sure to get these proofs ready beforehand. This way you can attach the requirements straightaway.

Tip:

Did you know there are a range of free scanning apps, such as Adobe Scan* that can also help save you time and improve the accuracy and quality of your case packaging.

Most scanning apps are free and easy to use, helping reduce the time it takes for your clients to get their mortgage offer. To download, please visit the appropriate App store for your device.
