A lot of a loan officer’s time after an application comes in doesn’t go to the borrower. It goes to the file. Paystubs, W-2s, bank statements, tax returns, a photo ID, maybe a gift letter. Each one has to be opened, checked, and understood before the loan can move.
Most of that review happens one document at a time. That’s where much of the time goes, because the questions that actually hold a loan up rarely live inside a single document. They live between them.
Each document in a file gets checked on its own terms. Is it the right one? Is it complete, current, and legible? That work matters, but a paystub can pass every one of those checks and still raise a question once you compare it to the income on the application.
Bank statements are a good example. Fannie Mae’s Selling Guide defines a large deposit as a single deposit that exceeds 50% of the borrower’s total monthly qualifying income. If those funds are going toward the down payment, closing costs, or reserves, the lender has to document where they came from. So whether a deposit needs attention depends on the income documentation, not just the statement it appears on. The bank statement can’t answer that question by itself.
The same is true across the whole file. The application, income documents, asset statements, and conditions all describe the same borrower. The real review is making sure they tell the same story.
When documents are reviewed in isolation, the connecting work falls on the loan officer. They open one file, then another, keep numbers in their head or on a notepad, and piece together what’s missing or what doesn’t line up.
It also tends to happen in rounds. A missing page gets caught on Monday. A deposit that needs an explanation gets caught on Wednesday. Each discovery means another request to the borrower, another wait, and another pass through a file the LO has already been through once.
That time shows up on the cost side. MBA’s latest performance data put the average production cost at $10,936 per loan in the second quarter of 2026. Not all of that is file review, but hours spent re-reading the same documents are part of what lenders are paying for.
The real gain from AI here isn’t reading any single document faster. It’s an AI review that looks at the file as a whole. Instead of a series of separate checkmarks, the loan officer gets one picture: what the loan looks like, what’s missing, what doesn’t line up, and what might need an explanation.
That changes the order of the work. The LO starts with a summary instead of a stack. Questions that might have surfaced over several days show up together and early, while there’s still time to handle them in one conversation with the borrower instead of three.
It doesn’t replace judgment. Deciding whether an explanation makes sense, or how to talk to a borrower about it, is still the loan officer’s call. The AI just gets them to that point sooner.
For lenders evaluating AI, the useful question isn’t only whether a tool can read a document. It’s whether it helps a loan officer understand the loan.
That’s the thinking behind the AI document review in LiteSpeed Intelligence. AI Sidekick analyzes the loan file, summarizes it, surfaces potential red flags and discrepancies, and identifies missing documents. It can also recommend letters of explanation and needs-list items, and translate conditions into clearer language. Alongside it, Document Agent handles the organizing work: splitting, rotating, renaming, and classifying uploaded documents, then sending them to the Encompass eFolder.
The loan officer stays in control of what happens next. The review just starts from the whole picture instead of page one.
Borrowers don’t think of their loan as a set of separate documents, and loan officers shouldn’t have to review it that way either. The time AI saves doesn’t come from reading each page a little faster. It comes from showing how the pages fit together, so the LO knows where the file stands and what to do next without piecing it together by hand.
