Prequalified vs. Preapproved for a Mortgage: What’s the Difference?

If you’re getting ready to buy a home, one of the first things you’ll hear is that you need to get preapproved. But what does that actually mean — and how is it different from being prequalified? And what about a loan commitment letter, or being pre-underwritten?

These terms get used interchangeably, but they are not the same thing. The difference matters — especially in a competitive market where sellers are evaluating the strength of every offer on the table.

Here’s a simple breakdown of each level and what to look for.

Prequalified: The Starting Point

Getting prequalified is the first step in the mortgage process. At this stage, a loan originator collects basic information about your income, assets, and debts — often through a phone or online interview — to get a general picture of what you might qualify for.

Your credit may or may not be pulled at this point. The information you provide hasn’t been verified yet. No W-2s, no paystubs, no bank statements — just what you’ve told the lender.

A prequalification letter can be issued quickly and it does serve a purpose: it tells you roughly what price range to shop in and gives you a chance to evaluate the loan originator before you commit to working with them. But it is not a commitment to lend, and a seller’s agent knows that.

A prequalification letter is the minimum. In most situations, you’ll want to be fully preapproved before making an offer.

Preapproved: What It Actually Means

A true preapproval means you’ve provided all the supporting documentation to back up your application — and the lender has reviewed it.

To be considered preapproved, at minimum you should have:

• Completed a loan application
• Provided income documents, like W-2s, paystubs and possibly tax returns
• Supplied documents to show where your funds for closing are coming from, such as your bank statements or asset accounts.
• Had your credit report pulled and reviewed
• Had your loan scenario run through AUS (automated underwriting)
• Received “findings” from the AUS that detail what’s needed for final approval

Once all of that is in order, your loan originator prepares a preapproval letter that can be used when presenting an offer. A well-prepared preapproval letter should include the date, your name(s), the loan amount and sales price you’re approved for, the loan type (conventional, FHA, VA, etc.), confirmation that credit, income, and assets have been reviewed, and any conditions the approval is subject to — such as a satisfactory appraisal and clear title.

Note that a standard preapproval letter is typically prepared by the loan officer. It does not necessarily mean an underwriter has reviewed your file — though for more complex scenarios, that’s exactly what I do before issuing the letter.

If you haven’t provided your supporting documents to your loan originator, you’re prequalified — not preapproved.

Pre-Underwritten: The Strongest Approval

Being pre-underwritten means your full application and documentation have been reviewed and approved by a human underwriter before you’ve even found a home. This is the highest level of approval you can have going into a home search.

The pre-underwritten approval has largely replaced what used to be called a loan commitment letter, which served the same purpose — a lender committing to finance the loan based on the borrower’s file, subject only to property conditions.

Here’s a quick way to check where you stand: ask your loan originator for the underwriter’s name. If they say “Fannie Mae” or “Freddie Mac,” that’s the automated underwriting system — not a human underwriter. AUS approval is part of a standard preapproval, but it’s not the same as having your file reviewed by an actual underwriter.

Why does this matter? A pre-underwritten approval:

• Gives you and your agent real confidence in your buying power
• Can help your offer stand out over buyers who are only preapproved or prequalified
• Speeds up closing once you’re under contract, since much of the underwriting work is already done
• Catches potential issues early — before you’ve fallen in love with a house

Does Getting Preapproved Hurt Your Credit Score?

This is one of the most common questions I hear, and it’s a reasonable one. When a mortgage lender pulls your credit, it does create an inquiry that may temporarily lower your score by a few points. But a few things are worth knowing:

First, getting your credit pulled early is actually an advantage. If there’s anything on your report that needs to be addressed — a payment reported late, an old collection, a score that’s lower than you expected — you want to find that out now, not the week you’re trying to make an offer.

Second, mortgage rate shopping is treated differently than other types of credit inquiries. Multiple mortgage credit pulls within a short window are generally counted as a single inquiry for scoring purposes. So shopping lenders won’t compound the impact the way buying a car and applying for a credit card at the same time would.

Third, if you’re a few months away from buying, small steps can make a meaningful difference. Paying a credit card balance down below 30% of the credit limit, for example, can move your score more than you’d expect — and a better score can mean a better rate. Before making ANY changes to your credit, please check with your mortgage professional.

Bottom line: don’t let concern about a small credit score dip stop you from getting preapproved. Start the process early so there’s time to work through anything that needs attention.

What Can Change After You’re Preapproved?

A preapproval is not a guarantee. Several things can affect it between the time it’s issued and the time you close:

• Mortgage rates. Your preapproval is based on rates at the time it was prepared. Rates aren’t locked until you’re under contract. If rates rise dramatically before you find a home, your qualifying payment may change.
• Your financial picture. Any changes to your employment, income, debts, or assets can affect your approval. Don’t buy a car, change jobs, open new credit accounts, or make large undocumented cash deposits without talking to your loan originator first.
• Property-specific costs. Property taxes, homeowners insurance, and HOA dues are not known until you’ve identified a specific home. These all factor into your debt-to-income ratio and can affect how much you qualify for at a given payment.
• Mortgage insurance. For FHA, VA, and USDA loans, funding fees and mortgage insurance premiums are set by the program and can change over time.

This is why I often prepare updated preapproval letters for clients as they make offers on specific homes — to make sure the numbers reflect the actual property taxes and HOA for that property.

How Long Is a Preapproval Valid?

Most preapproval letters are valid for 90 days, which aligns with when lenders consider a credit report to be stale. Updating a preapproval is usually straightforward — in most cases it means refreshing the credit pull and providing updated paystubs and bank statements. If your situation hasn’t changed significantly, the process is quick.
