How Long Does a Mortgage Preapproval Last in Wisconsin?

Most mortgage preapprovals are good for 60 to 90 days. If you got yours during the spring market and you are still touring homes in October, it has almost certainly gone stale — and in a competitive offer, a stale preapproval letter is the fastest way to look unserious to a listing agent.

This comes up constantly this time of year. A buyer gets preapproved in April, loses out on two houses, takes the summer off, then starts looking again when the fall inventory shows up. The letter in their inbox is five months old. Here is what that means, and how little work it takes to fix.

How long is a preapproval actually good for?

There is no single state or federal rule setting the clock, so the window comes from the documents behind the letter rather than the letter itself. In practice, a Wisconsin preapproval holds up for about 60 to 90 days, because that is roughly how long the underlying pieces stay current:

• Your credit report — the pull behind a preapproval is generally considered usable for around 90 to 120 days.
• Income documents — pay stubs and bank statements are expected to be recent, usually within the last 30 to 60 days at the time you write an offer.
• Your own situation — jobs, balances and debts move, and the older the file, the less anyone can rely on it.

Some lenders print an expiration date on the letter. Others do not, which is worse: the letter looks permanent when the file behind it is not.

Why do preapprovals expire at all?

Because a preapproval is a snapshot, not a promise. It says: based on what we verified on this date, this buyer can borrow roughly this much. Every input in that snapshot has a shelf life. An underwriter looking at a five-month-old file cannot tell whether you have since financed a truck, changed employers, or co-signed for a family member — all of which genuinely change the answer.

The expiration also protects you. A letter nobody has re-checked can have you shopping in a price range you no longer qualify for, which is a painful thing to discover after your offer is accepted.

What happens if mine expires mid-search?

Nothing dramatic, and nothing permanent. You are not back to square one and you do not start a new application from scratch. Renewing a preapproval usually means sending updated pay stubs and recent statements, confirming nothing major has changed, and getting a fresh letter dated this week. For most buyers it is a same-day or next-day turnaround.

What you should not do is write an offer on the old letter and hope nobody checks the date. Listing agents look. A current letter is one of the cheapest forms of credibility you can hand them.

What changes between the first letter and the renewal?

Sometimes nothing. Sometimes quite a lot, and that is worth knowing before you are under contract. Take a buyer preapproved in April for a $320,000 purchase in Waukesha. By October three things had moved: she had paid off a car, her employer added a bonus structure, and taxes on the homes she was targeting had been reassessed. Two helped her, one did not. Her renewed letter came back at a different number — and she would far rather learn that in October than during underwriting.

So treat the renewal as a check-in, not paperwork. It is a chance to ask whether the price range still fits, whether a different program suits you better now, and what your document list looks like for the offer you are about to write.

What should you do if you are still shopping this winter?

Winter is a quieter market in Wisconsin, which is exactly when a buyer with a current letter has an edge. A practical rhythm for the next few months:

1. Refresh the letter now if yours is more than about 60 days old, even if you have not found the house yet.
2. Tell me before you take on new debt. A financed appliance set or a new vehicle is the single most common reason a renewal comes back lower.
3. Re-date it again before the spring market. If you are still looking in February, go in with a letter written in February.

The bottom line

A preapproval is not a document you earn once and keep. It is a current read on where you stand, and it goes out of date on purpose. Keeping it fresh takes a few minutes and two documents, and it is the difference between an offer a listing agent takes seriously and one they set aside.
