One Folder Per Loan, Named by Borrower and Loan Number
The appraisal is in the inbox, the title commitment is in a portal, the initial disclosures are in the origination system, and the borrower documents are spread across four email threads.
The short answer
A loan file is one folder per loan, named with the loan number and the borrower, holding everything from every source. The documents identify themselves: the loan number is on the disclosures, the property address is on the appraisal and the title commitment, and the borrower name is on nearly everything. A workflow uses the Read Details from File step to pull those off, the Rename step to name the file by date and document type, and the Move step to file it under the loan. The Email Attachment trigger is what covers the appraiser and the title company, who send by mail.

Four documents from four different senders, filed under the loans they belong to by the loan number or the property address printed on them.
Setting it up
Described once, then it runs
This is the sentence. Send it to the builder and the steps below appear on a canvas, wired and named, for you to change before anything runs.
When a loan document arrives, read the loan number, the borrower name or the property address off it, rename it date-first with the document type, and file it under that loan.
Loan number and borrower in the folder name
The loan number is what the system knows and the borrower name is what people say out loud. Putting both in the folder name means the folder is findable whichever one you happen to have in front of you.
Route on the property address too
An appraisal and a title commitment often carry the address and no loan number at all. Reading the address off the document and matching it to the open loan is what stops those two from being the ones somebody always files by hand.
Name by date and document type
A loan folder that reads chronologically shows the shape of the file at a glance: disclosures, borrower documents, appraisal and title, conditions, closing. That is faster to work with than any scheme of subfolders.
Stop on the ones that name nothing
A signature page or a one line email attachment sometimes identifies no loan at all. The Ask AI About the File step sends those to review, because a document filed under the wrong borrower costs far more here than in most filing.
The documents come from everywhere except one place
A loan file is assembled from the borrower, the appraiser, the title company, the insurance agent and underwriting, and each of them sends the way they send. Some use a portal, most use email, and a few fax to an address that turns into email. The common factor is not the channel, it is that the document says which loan it belongs to, which is why reading the document beats routing on the sender.
The property address is the second key and it earns its keep
Appraisals, title commitments, flood certificates and insurance binders are produced by people who do not have your loan number and do not need it. They identify the property. Matching an address to an open loan is the difference between those documents filing themselves and those documents being the ones that are always done by hand, which over a month is most of the filing time on a desk.
What it does not do
It files loan documents under the right loan and names them so the folder reads in order. It does not clear conditions, calculate anything on a disclosure, or check that a document is the current version of a form. It does not move documents into a loan origination system. It is the filing underneath the loan rather than the running of it.
Limits
What to know before you build it
It runs on new files, not your backlog
This workflow fires when a file arrives. It will not go back over the documents already sitting in the folder, so switching it on leaves the existing pile exactly where it is. Working through what is already there is a scheduled run instead, which is a different workflow.
Organize the files you already haveIt needs a connected account
This workflow reads files out of an email inbox, so it cannot run until that account is connected. Connecting one is on the Max plan, or on any team workspace. There is no version of this particular workflow that runs on the free plan, because the files it organizes never arrive in The Drive AI on their own.
FAQ
Common questions
How should mortgage loan files be organized?
One folder per loan, named with the loan number and the borrower surname, with every document named date-first by its type. Subfolders by document category cost more in filing decisions than they return in findability, because the filenames already say what each document is.
How do you file documents that only show the property address?
Read the address off the document and match it to the open loan for that property. Appraisals, title commitments and insurance binders are produced by parties who identify the property rather than the loan, and that is exactly why they are the documents most often filed by hand.
What happens to files for loans that do not close?
They stay in the loan folder. A withdrawn or denied file still carries retention obligations and is still what you would need if a question came back later, so archiving the folder is the right move rather than clearing it out.
Does this work across more than one loan officer?
Yes, and the value goes up. A consistent folder shape means somebody covering a file they did not originate can open it and see what is there, which is the situation where a personal filing habit costs the most.
The file assembles itself.
Every document under its loan, read off the page rather than sorted by hand.
