What Does the Mortgage Approval Process Look Like?

Mortgage approval happens in five stages: preapproval, the formal application and Loan Estimate, processing and the appraisal, underwriting and conditional approval, then clear to close and the Closing Disclosure before you sign. The lender's underwriter makes the approval decision, and the loan is not final until the underwriter signs off on the last conditions shortly before closing. Purchase loans that closed in March 2026 took an average of 36.8 days from application to closing, according to ICE Mortgage Technology.

The stages at a glance

The time figures are ICE's March 2026 averages for purchase loans. Your loan can run faster or slower depending on the lender's workload and how quickly you answer requests.

1. Preapproval: before you make an offer

A preapproval letter states how much a lender is willing to lend you, based on your credit, income, savings, and debts. The CFPB notes that it is not a guaranteed loan offer, but it gives a seller a reason to take your offer seriously. Lenders use the labels differently: some call a letter based on what you tell them a prequalification and use preapproval only for one based on verified documents, so ask which kind you are getting.

The lender may pull your credit at this stage. If it decides you do not qualify, it must send you an adverse action notice. How to get preapproved covers what the lender checks and how long the letter lasts. If you plan to compare lenders, how mortgage credit checks affect your score explains how to keep several checks from counting as several inquiries. If you have no credit score at all, see qualifying with no credit history.

2. Application and Loan Estimate

Once a seller accepts your offer, you complete the full application, the Uniform Residential Loan Application (Fannie Mae Form 1003). For federal disclosure rules, your application counts as received once you give the lender six things: your name, income, Social Security number, the property address, an estimate of the property's value, and the loan amount you want.

From that point, the lender has 3 business days to deliver or mail a Loan Estimate, a standard form showing the rate, monthly payment, and closing costs it expects to offer. Three rules apply here:

• Fees wait. Until you receive the Loan Estimate and tell the lender you want to proceed, it can charge you only a reasonable fee for your credit report. Application and appraisal fees come after.
• You must say yes. You have at least 10 business days after the lender provides the Loan Estimate to indicate that you want to proceed before it can expire. An unlocked interest rate can change during that period, and qualifying changes in circumstances can permit revised estimates. The lender cannot treat your silence as a decision to go ahead.
• You are not locked in. The CFPB's toolkit says you are not committed to any lender until you sign the final closing documents.

After you say you want to proceed, the lender asks for full documentation. What documents you need to apply has the checklist by borrower situation.

3. Processing, rate lock, and the appraisal

A loan processor collects your pay stubs, W-2s, bank statements, and the purchase contract, verifies them, and orders the appraisal and title work. The processor assembles the file; the processor does not approve the loan.

Rate lock. Your Loan Estimate shows a rate that is either locked or floating. A lock sets the rate for a period, typically 30, 45, or 60 days, and it can be expensive to extend if closing slips. Even a locked rate can change if your loan amount, credit score, or verified income changes, in which case the lender sends a revised Loan Estimate.

Appraisal. The lender orders the appraisal from an independent appraiser, who estimates the home's market value for the lender. Within 3 business days of your application, the lender must tell you that you have a right to a copy. It must give you the copy as soon as the appraisal is done or at least 3 business days before closing, whichever comes first, unless you waive advance receipt and agree to receive it at closing. The lender generally must obtain that waiver at least 3 business days before closing. An appraisal that comes in lower or higher than expected is one of the reasons the CFPB lists for a revised Loan Estimate; how a lender evaluates a property covers your options when the value falls short.

Some conventional loans skip the appraisal. Fannie Mae's automated underwriting system, Desktop Underwriter (DU), offers value acceptance on certain loan files, which means no appraisal is required. Purchases at $1,000,000 or more do not qualify.

Title. Most lenders require a lender's title insurance policy, which protects the amount they lend if someone later claims an interest in the home, such as from a past owner's unpaid taxes or an unpaid contractor. The title company searches the records before closing.

4. Underwriting and conditional approval

The underwriter is the person who approves or denies the loan. Underwriting means confirming your credit and financial information is accurate and that you meet the lender's requirements. Many conventional loans first run through DU, and the underwriter then reviews the file against the recommendation: credit history, debt-to-income ratio, income, savings, and the appraisal.

The underwriter often issues a conditional approval, meaning the loan is approved once you supply specific items. Examples:

• An updated pay stub or bank statement because the earlier one aged out.
• Proof of homeowners insurance on the new home.
• The source of a large deposit. Fannie Mae defines a large deposit as a single deposit over 50% of your total monthly qualifying income, and the lender must document where it came from if you use that money for the purchase. If you earn $6,000 a month, any single deposit over $3,000 needs a paper trail if you use it toward the purchase.

Answer conditions the same day if you can, since each one goes back to the underwriter for review. If your loan is turned down, what to do after a mortgage denial covers next steps.

Your file has to hold steady until closing. The CFPB warns that even financing a new refrigerator before you close could make it harder to get the mortgage. Under Fannie Mae's rules, the lender generally rechecks salaried employment on or within 10 business days before the date on your mortgage note. That window can extend to 15 business days before the note date if supporting documents are dated within that period and reflect the most recent pay period. A job change late in the process can stop the loan.

5. Clear to close, Closing Disclosure, and closing

When the underwriter has signed off on every condition, the lender issues a clear to close. The lender must then make sure you receive the Closing Disclosure, a 5-page form with your final loan terms and costs, at least 3 business days before you sign.

Compare it line by line with your Loan Estimate. The CFPB says the 10% cap on increases from your Loan Estimate applies to the combined eligible charges. These include recording fees and required services you can shop for when you choose providers on the lender's written list that are unaffiliated with the lender or broker. Choosing a provider outside that list removes the percentage cap for that service. Qualifying changes in circumstances can permit revised estimates. Three changes after you receive the Closing Disclosure restart the 3-business-day wait: the annual percentage rate (APR) changes beyond a small tolerance, the loan product changes (for example, fixed to adjustable), or a prepayment penalty is added.

A settlement agent runs the closing in most of the country. In several Western states the role is called an escrow agent, and some states in the Northeast and South require an attorney. You sign the note and mortgage, and pay your cash to close.

How long does the whole process take?

A purchase loan takes a little over 5 weeks on average. ICE Mortgage Technology reported that purchase loans closed in an average of 36.8 days in March 2026, the fastest since it began tracking in 2019. The typical loan took 11 days from application to rate lock and another 26 days from lock to closing. Getting preapproved, and the time you spend house hunting before you apply, come on top of that.

Federal rules also set a floor: the lender cannot close the loan until at least 7 business days after it delivers or mails your Loan Estimate.

What can add time:

1. Missing or stale documents. Gathering everything before you apply means the processor is not waiting on you.
2. A low appraisal. A value below the price can mean renegotiating the price, adding cash, or changing the loan.
3. New underwriting conditions. Each late request adds a review cycle.
4. A Closing Disclosure redo. Any of the three changes described above restarts the 3-business-day wait.
