In short: chasing happens because the borrower can't see what's missing, gets no feedback when they send the wrong thing, and your requests are buried across email threads. The fix is a system, not more reminders: one source-of-truth checklist, one channel, structured requests with examples, automated nudges, and validation as documents arrive — not at the end. Brokers who run this system report files completing in days instead of weeks, with most of the chasing done by software.
A median purchase file needs somewhere between 15 and 40 documents, depending on the borrower's situation and your market. Self-employed borrower? Add tax returns, business accounts, accountant references. Co-borrower? Double most of it. And brokers consistently report losing several hours a week — some say a full day — to follow-up emails, "did you get my message?" calls, and re-requesting things that arrived wrong the first time.
That time isn't admin. It's the bottleneck on how many files you can run at once.
Why chasing happens (it's not the borrower's fault)
Before fixing it, it's worth being honest about the mechanics. Borrowers don't ignore you because they don't care — they're buying a house. They go quiet because the process makes it easy to stall:
- No shared visibility. You know what's outstanding. They don't. The list lives in your head, your CRM, or an email from nine days ago. When a borrower has to reconstruct "what do they still need from me?" by scrolling a thread, they put it off.
- No feedback loop on wrong files. They send a payslip — cropped, expired, or the wrong month. They think they're done. You only notice when you review the file later, then a new email goes out, then they're confused, then it's the weekend. Every wrong document costs three to five days if feedback isn't immediate.
- Requests buried in email. Your document list competes with everything else in their inbox. The original request gets buried under replies, the attachment limit bounces their bank statements, and version two of the list contradicts version one. Email is a conversation tool, not a checklist tool.
Notice that none of these are fixed by sending more emails. More emails are the problem.
The 5-part system
1. One source-of-truth checklist
Every file starts from a complete, written checklist — not a request typed from memory. Build templates per borrower profile: standard purchase, remortgage (refinance in the US/CA), self-employed, buy-to-let, co-borrower. When the list is complete from day one, you don't drip-feed requests, and the borrower never gets the demoralising "oh, one more thing" email.
If you don't have templates yet, start with our mortgage document checklist and the self-employed variant and adapt them to your lenders.
UK advisers: this is effectively the document half of your fact find, formalised. AU brokers: align it with what your aggregator's lender panel actually asks for, not the generic list.
2. One channel
Pick one place where documents live and requests are visible — and stop accepting documents anywhere else. The moment some files arrive by email, some by WhatsApp, and some by hand, you've lost the single view of what's outstanding, and you're back to reconciling sources.
A dedicated borrower portal is the strongest version of this, but even a disciplined shared folder beats scattered channels. The test: can both you and the borrower see, at a glance, exactly what's missing right now? If not, you'll be chasing.
3. Structured requests with examples
"Send me your bank statements" produces screenshots, single pages, and statements from the wrong account. A structured request specifies, per document:
- Exactly what: "Last 3 months of statements for the account your salary is paid into"
- Format: "PDF downloaded from online banking — not screenshots"
- Validity: "Dated within the last 30 days"
- An example where ambiguity is common (what a 'full' payslip looks like, where to find a tax computation)
This feels pedantic. It is pedantic. It's also the single highest-leverage change on this list, because every ambiguity you remove is a wrong document you don't re-request.
4. Automated reminders
Manual chasing fails for a boring reason: it depends on you remembering, and you're busy. Automate it. A reminder that goes out at day 3 and day 7 — referencing the specific missing items, not "your documents" — does the chasing without consuming your week.
Two rules make reminders work:
- Reminders list what's missing, so the borrower can act from the reminder itself.
- Reminders stop the moment the file is complete. Nothing erodes trust faster than nagging someone who already finished.
5. Validate as documents arrive — not at the end
This is where most processes quietly fail. Documents trickle in over two weeks, you review the lot the night before submission, and discover the payslip is from the wrong month and the ID is expired. Now you're chasing again — under deadline pressure.
Instead, review each document within a day of arrival. Approve it, or reject it with a reason the borrower sees immediately ("this statement is missing page 2 — please re-download the full PDF"). The correction happens while the borrower is still engaged, not three weeks later when they've mentally moved on.
| Old way | System way |
|---|---|
| Requests drip-fed by email | Complete checklist on day one |
| Documents in inbox, WhatsApp, folders | One channel, one live status |
| "Send your bank statements" | Specific format, validity, example |
| Chasing when you remember | Automatic day-3 / day-7 nudges |
| Review everything pre-submission | Validate within 24h of arrival |
What changes in practice
The compound effect is bigger than any single part. A complete checklist means fewer total requests. One channel means no reconciling. Structured requests mean fewer wrong documents. Automated reminders mean the follow-ups happen without you. Early validation means errors cost a day, not a week.
Brokers who switch to this kind of system typically see time-to-complete-file drop from two-plus weeks to a few days, and — just as important — the hours they personally spend chasing drop to near zero. The chasing still happens; it's just done by software, politely, on schedule.
You can run a rough version of this with templates and calendar reminders. It works, but it leans on your discipline, and discipline is exactly what runs out in a busy month.
Run the system without building it yourself
Dossia is this five-part system as a product, built for mortgage brokers. Each borrower gets one private link — no account, no app to install — showing exactly what's outstanding. Reminders go out automatically. You validate or reject each document in one click, with feedback the borrower sees instantly, and export a bank-ready file when it's complete. EU hosting, GDPR-compliant by design.
