Quick answer

Use only the fax number your lender or broker gave you directly, confirmed with a phone number you already trust. Put your name and loan or application number on every page, combine all documents into one PDF, and fax it online. Keep the send report. If the lender offers a secure upload portal, that's usually their preferred option.

Buying a home or refinancing comes with a lot of paperwork: pay stubs, W-2s or tax returns, bank statements, signed disclosures, insurance details. Most lenders and brokers today use secure portals, but some still ask for a fax, especially smaller lenders, brokers, and title or settlement offices. Here's how to do it without a fax machine and without mistakes.

First: verify the fax number

Real estate and mortgage closings are a known target for fraud. Scammers send fake emails that look like they come from a lender, title company, or agent, sometimes with changed contact details. Before you send personal financial documents:

  • Use the fax number from your loan paperwork or the lender's official website.
  • If you got a new or changed number by email, call your loan officer at a phone number you already know (not one from that email) to confirm it.
  • Never change where you send money based on an email alone.

What to put on every page

  • Your full name (and your co-borrower's, if any)
  • Your loan or application number
  • Page numbers, for example "3 of 12"

A short cover sheet helps your documents reach the right person: loan officer or processor name, your contact phone, the number of pages, and a one-line list of what's enclosed. See What to put on a fax cover sheet.

Step by step: fax your mortgage documents online

  1. Download statements as PDFs from your bank or payroll portal, or scan paper documents with your phone.
  2. Black out information your lender didn't ask for, if your lender allows it (for example, unrelated account numbers on a combined statement). Ask first, since some lenders need complete statements.
  3. Open sendfaxfast.com and upload all files. Several files for the same number are combined into one fax, up to 100 pages and 10 MB.
  4. If a form needs your signature, you can sign on screen after uploading. It is a simple image signature, so ask your lender whether that is accepted for the document.
  5. Enter the fax number, pay for that one fax, and keep the send report you get by email.

Should I fax or use the lender's portal?

If your lender has a secure document portal, it's usually what they prefer, and it keeps everything in one place. Fax is a good fallback when the portal isn't working, when a broker or settlement office asks for a fax, or when you need to send something today and want a send report with a time stamp.

Australia and New Zealand

The steps are the same if your bank or broker in Australia or New Zealand asks for a fax. Enter the number in international format: +61 for Australia or +64 for New Zealand, without the leading 0.

Frequently asked questions

Can I fax bank statements to my mortgage lender?

Yes, if your lender accepts faxes. Use the fax number from your loan paperwork or the lender's official website, and put your name and loan number on every page.

Is it safe to fax financial documents?

Fax is sent directly to the number you dial, so the biggest risk is a wrong or fake number. Confirm the number with your loan officer by phone, and check every digit before you send.

How do I fax multiple documents to my lender at once?

Upload all files on sendfaxfast.com. Files for the same number are combined into one fax automatically, up to 100 pages and 10 MB.

Can I sign mortgage forms online before faxing?

SendFaxFast lets you add a simple image signature after uploading. Whether that is accepted for a specific mortgage document is up to your lender, so ask first.

Will I get proof that I sent the documents?

Yes. You get a send report by email with the date, time, fax number, and an image of the first page.
