Pre-qualified, pre-approved, underwritten: not the same offer

A pre-qualification letter is a lender's quick estimate, often based on numbers the buyer simply reported. A pre-approval letter is stronger, because the lender actually checked income, assets, debts and credit before writing the number down, though it is still not a guaranteed loan. Underwriting is a separate stage entirely: the lender's full review of the real file after a buyer is under contract, ending in an actual approval or denial. The three happen in that order, and only the last one is a lender saying yes for real.

What is the difference between pre-qualified, pre-approved and underwritten?

The Consumer Financial Protection Bureau's own guidance warns that lenders use "prequalification" and "preapproval" inconsistently, so the label a lender chooses doesn't say much about what it actually did. Both describe a letter stating the lender is generally willing to lend up to a certain amount, based on assumptions, and the bureau is direct that neither one is a guaranteed loan offer. What separates them in practice is verification: some lenders will issue a pre-qualification letter on numbers the buyer simply reports, and save a true pre-approval for a letter backed by checked income, assets and credit. Underwriting is a different stage of the same loan, not another version of the same letter. It happens after a buyer has a signed purchase contract, when the lender processes the full application, verifies everything behind it, and approves or denies the actual loan.

What does a pre-qualification letter actually check?

A pre-qualification letter from some lenders rests on unverified information, numbers the buyer reports about income, assets and debt that nobody on the lender's side has confirmed yet. The bureau notes that a lender may or may not even run a credit check to produce one. That makes a pre-qualification letter useful for a buyer still working out a rough budget, since it costs nothing and takes little time, but it carries less weight once there's a real house and a real seller comparing offers, because nothing behind the number has actually been checked.

What does a lender verify before issuing a pre-approval letter?

A true pre-approval starts from the same assumptions a pre-qualification does, but a lender issuing one has looked at the buyer's income, assets, debts and credit record rather than taking the buyer's word for them. The letter still carries a cap, a specific loan amount it's good up to, and the bureau's guidance says it typically expires 30 to 60 days after it's issued, which is one more reason to get it close to when house hunting actually starts rather than months ahead. Even with that verification behind it, the bureau is still plain that a pre-approval letter "is not a guaranteed loan offer." It's a lender's considered opinion of what it will likely do, not a commitment that survives whatever the file turns up next.

What happens to an application between pre-approval and the final decision?

Once a buyer has a signed contract, the lender moves from the pre-approval's assumptions to verifying the actual file. The bureau describes the lender following up to request documents that confirm what the buyer already submitted, and processing that information until it has everything it needs to decide. Two of the most common things that change the numbers at this stage, per the bureau's guidance on revised Loan Estimates, are a home appraisal that comes in under the sale price and overtime, bonus or other irregular income the lender ultimately can't document the way the buyer described it. Either one can mean a different loan amount, a different rate, or a different set of terms than the pre-approval letter implied, which is why that letter was never the final word.

What can a buyer do if a loan is denied after pre-approval?

A pre-approval is not a guarantee, so the file can still come back denied once the lender finishes checking it. If that happens, the bureau says a buyer can request an explanation in writing, and the lender has to provide one. From there, the bureau points a denied buyer toward pulling a free credit report to look for mistakes, talking to a HUD-approved housing counselor, and remembering that a different lender can still approve the same file, since being denied by one does not require being denied by another.

Which of the three should a buyer have before making an offer?

A seller reading two offers side by side is reading two letters that might say nearly the same thing on paper and mean very different amounts of lender work behind them. Because the bureau points out that "prequalification" and "preapproval" aren't used the same way from lender to lender, the stronger move is asking any lender directly whether its letter rests on verified income, assets and credit, or on what the buyer reported. Underwriting isn't part of this choice at all. It doesn't start until there's a signed contract, so no buyer brings an underwritten loan to an offer; the strongest paper available before that point is a pre-approval a lender actually verified.

The question worth asking any lender before writing an offer isn't what the letter is titled, it's what the lender actually checked to produce it. Our vendor list has the lender we refer buyers to when that conversation needs to start.
