Approval isn’t one moment. It’s a sequence — and most of the anxiety I see comes from people treating it like a single yes-or-no verdict that lands at the end. It doesn’t work that way. There are clear stages, each one stronger than the last, and at every step I can tell you precisely where your file stands and what’s left.

Underwriting is the engine underneath all of it. An underwriter isn’t looking for a reason to say no. They’re confirming, with documents, that the picture you described on your application is real and repeatable. When you know what they check and why, the process stops feeling like a black box and starts feeling like a checklist.

This page walks the whole thing: the stages from prequalification to funding, the four things underwriting evaluates, what a “condition” actually is, and the short list of moves that can quietly undo an approval you already have.

The five stages, from guess to funded

Each stage answers a stronger question than the one before it. The gap between the first two is where most people get a false sense of certainty — so I won’t let a buyer of mine make an offer on anything weaker than stage two. The whole sequence usually fits inside a 30-day purchase; here’s how long underwriting takes at each step.

1. 1

   Prequalification

   A back-of-the-envelope estimate built on what you tell me, with nothing verified. It’s useful for orientation and almost worthless to a seller. A prequal answers “roughly, could this work?” — not “will this close?” I explain why the distinction matters in pre-approval vs. prequalification.

2. 2

   Pre-approval

   Now the numbers are real. I run a soft credit check, review your actual income documents, and produce a true cost sheet against a real loan amount. This is the number that holds up when you write an offer, because it’s been checked rather than claimed.

3. 3

   Conditional approval

   You’re under contract, the file is with an underwriter, and they’ve issued a yes — with a list. That list is the “conditions.” It is completely normal, even on a strong file, and it is not a sign of trouble. It’s the underwriter saying “approved, once you hand me these specific items.”

4. 4

   Clear to close

   Every condition has been satisfied and signed off. The loan is approved with nothing outstanding, the closing disclosure goes out, and the clock starts on the mandatory three-day review window before you can sign.

5. 5

   Closing and funding

   You sign, the lender funds, and the deed and mortgage record. On a purchase the keys are yours; on a refinance you get a three-day right to cancel after signing before the loan funds. This is the moment everything has been building toward, and by the time you reach it there should be no surprises left.

The four things an underwriter is actually checking

Underwriting is old, and the framework is older — four C’s that every file gets measured against. Almost every condition an underwriter raises traces back to one of these. I break down each one in what underwriters actually look for.

What a “condition” really is, and why it isn’t personal

When a file comes back “conditionally approved” or “suspended,” people read it as bad news. It almost never is. A condition is just a specific item the underwriter needs in hand before the approval is final — a recent pay stub, a letter explaining a deposit, an updated bank statement, proof a debt was paid off. “Suspended” usually means the same thing with a pause attached: the underwriter needs something before they keep going.

The document requests can feel relentless, especially the second and third round. That’s not suspicion — it’s a paper trail. An underwriter can only approve what they can prove, and the cleanest files still generate conditions. My job is to anticipate most of them up front so the list at this stage is short, and to translate anything that sounds alarming into plain English. The two milestones people most often mix up — conditional approval and clear to close — I compare in conditional approval vs. clear to close.

The moves that can undo a loan you already have

An approval is a snapshot of your finances at a moment in time, and lenders re-verify some of it right before closing. A few common changes can knock a file out of its own approval — and they catch good borrowers off guard because they feel harmless.

The big three: changing jobs mid-process, which resets the income picture the underwriter just confirmed; opening new credit — a car loan, a furniture line, even a new card — which moves your debt-to-income and your score; and moving large sums between accounts without a clear paper trail, which turns a clean asset picture into a sourcing problem. None of these mean you can’t do them eventually. They mean timing matters, and a quick text before you act can save the loan.

I’d rather you ask first than explain after. If you’re mid-process and weighing any financial move, that’s exactly the kind of thing to run by me before it happens. The job-change version of this comes up constantly — I walk through it in can I change jobs before closing?
