Secure File Sharing for Mortgage Brokers

Mortgage brokers and real estate agents move sensitive documents through every deal -- pre-approval letters, W-2s, bank statements, purchase contracts, and disclosure forms. Email attachments bounce or expire, WeTransfer links disappear after a week, and neither gives you a record of who downloaded what. A branded client portal gives every client a private space to upload and download files under your firm's name, with a timestamped log of every action.

What documents go back and forth?

The typical mortgage file involves documents moving in both directions -- you collect financial evidence from the client, then deliver disclosures and closing packages back to them. Real estate agents add another layer: contracts, inspection reports, and title documents cycling between multiple parties on a deadline. Here is what the full checklist looks like:

• Pay stubs and employment verification letters -- from client to broker, often time-sensitive during underwriting
• Bank statements and asset documentation -- last two to three months, with account numbers visible
• Federal tax returns (W-2s and 1040s) -- include Social Security Numbers and detailed income history
• Credit authorization forms and gift letters
• Loan estimates and closing disclosures -- from broker to client, showing the full financial terms of the deal
• Purchase agreements and counteroffers -- signed PDFs cycling between buyer, seller, and both agents
• Inspection reports and appraisal reports
• Title commitments and settlement statements

Why email and WeTransfer fall short

Email and WeTransfer share three structural problems for this kind of work: files bounce on attachment size limits, transfer links expire, and there is no record of who actually downloaded what. For mortgage brokers and real estate agents, that last gap is the one that causes disputes -- a missing download confirmation is not a minor inconvenience, it is a liability.

Most corporate mail servers cap incoming attachments at 20 to 25 MB. A closing disclosure package with all addenda regularly exceeds that. WeTransfer's free tier expires links after seven days -- appropriate for a quick file handoff, not for a financial document the client may need to reference weeks after closing. And when a client says "I never received that," neither platform gives you anything more than a sent timestamp to point to.

The FTC Safeguards Rule for mortgage brokers

Mortgage brokers are classified as financial institutions under the Gramm-Leach-Bliley Act (GLBA). That means the FTC Safeguards Rule applies directly. Revised in 2023, it requires a written information security program covering how customer nonpublic personal information (NPI) -- including W-2s, bank statements, and Social Security Numbers -- is stored, transmitted, and accessed by anyone who handles it.

Using a dedicated portal per client -- with access controls and a download log -- is consistent with that obligation. To be clear: ProjectSend Cloud does not hold SOC 2, HIPAA, or ISO certification, and you should not cite it as a compliance solution. What it provides is encryption in transit and at rest, client-level access controls, a complete download history, and 2FA enforcement (Business plan) -- operational controls you can describe in your own security documentation.

How a client portal fits a mortgage brokerage

Each client gets a private, named account in your portal. They log in once, upload what you need, and download disclosures or final packages on their own schedule. You see every action in your admin panel -- timestamped, with the client's name attached to every download. When a client says "I never got that disclosure," you open the log instead of searching email threads.

The Pro plan ($19/month) includes 25 active client accounts, enough for most independent brokers. Additional active accounts are $0.40/month each. "Active" means the client has logged in at least once that month -- a completed transaction where the client is no longer active stops counting automatically. The Business plan ($49/month) removes the active client account limit and adds SSO and mandatory 2FA across your team. Full details at projectsend.cloud/plans.

The same pattern works for other professionals handling sensitive financial data. See how financial advisors use a client portal -- one account per client, full visibility into what has been shared and accessed.

Real estate agents: contracts, disclosures, and closing

Real estate agents face a tighter timeline: offer to close in 30 to 45 days, with documents moving between buyer, seller, both agents, the title company, and the lender. The risk is not just a lost file -- it is a file that went to the wrong party, or no clear record that the seller's disclosure was received before the inspection contingency period ended.

Real estate is one of the top sectors for business email compromise fraud, according to the FBI's Internet Crime Complaint Center (IC3). Attackers intercept document-sharing email threads and use them to redirect wire transfers at closing. Keeping all document exchange inside a dedicated, authenticated platform -- rather than open email chains -- removes the interception vector those attacks depend on.

A client portal does not replace your e-signature tool or your transaction management software -- it handles the file delivery layer that those tools leave to email. The buyer uploads the inspection notice; you upload the seller's response. Each version is in the client's account, timestamped, and available for audit after closing.

Getting started for free

The Free plan is a personal account on the shared instance -- 2 GB of storage, private links for your files, no expiry. There are no client accounts, no branded portal, and no seats on Free. It is a way to try the file delivery mechanics before committing to a portal. When you are ready for your own portal under your firm's name, Pro is $19/month and takes about five minutes to set up. No credit card required to start free.
