Buying a home involves more than finding the right property and picking a mortgage. Once you decide to apply for a loan, you enter a multistep process that requires paperwork, patience and careful attention to timing.
From gathering financial documents and comparing lenders to navigating underwriting and closing costs, each stage plays a role in determining whether your loan is approved — and on what terms. Understanding what happens at each step can help you avoid delays, spot potential issues early and feel more confident moving forward.
Here’s what to expect when applying for a mortgage loan, including how the process unfolds from application through closing and what borrowers can do to stay on track along the way.
Filling out a mortgage loan application

You’ll probably fill out a lender’s application online, and then talk with a loan officer by telephone. This is where the folder of financial information you’ve collected will come in handy. When filling out the application, you’ll need to provide borrower, property, employment and expense information.
Be prepared to give the name and phone number of someone who can verify financial information about you — most likely, your employer's personnel office. If you have substantial income from investments, you'll be asked to substantiate this through account statements and possibly an accountant, stockbroker, trust officer or similar source.
If you are self-employed or if 25% or more of your income is from commissions or bonuses, you must provide two years of tax returns to offer proof of established income. Self-employed people may also need a profit-and-loss statement so the lender can assess your company’s strength.
To begin processing of your application the lender may require a fee of $100 to $500 that covers the cost of pulling your credit report and obtaining an appraisal of the property's market value. The fees are non-refundable in most cases.
Review loan estimates
Once the lender has received your application, it will issue you a good faith estimate (GFE), which is mandated by the federal Real Estate Settlement Procedure Act (RESPA). Once you've obtained lenders' GFEs, you can compare their rates, closing costs and terms in an apples-to-apples format.
Check whether the quoted interest rate is guaranteed, and for how long. If you think that interest rates may rise while your application is being processed, ask for a "lock-in." Get it in writing.
Some lenders may offer a rate lock with a float-down option, meaning that if the rate goes down by a certain amount before you close, you will get the lower rate.
Loan processing

After you submit a mortgage application, the lender reviews your financial information to confirm you qualify for the loan. This typically begins with loan processing, where the lender collects and organizes documents such as pay stubs, bank statements, tax returns and employment verification.
At the same time, the lender orders a home appraisal to confirm the property is worth the purchase price and may also begin a title search to make sure there are no ownership disputes or liens tied to the home.
Once processing is complete, the loan moves to underwriting. The underwriter reviews your credit, income, assets, debts and the property details to determine whether the loan meets lending guidelines.
This is where you'll need patience. Borrowers are often asked to provide additional documentation or explanations during this stage. After all conditions are satisfied, the loan receives final approval, sometimes called "clear to close."
Before closing, the lender issues a Closing Disclosure outlining your finalized loan terms, monthly payment and closing costs. Federal rules require you to receive this document at least three business days before signing.
During this time, buyers typically secure homeowners' insurance, arrange funds for closing costs and complete a final walkthrough of the property.
Closing
At closing, you sign loan documents, funds are transferred and ownership of the home officially changes hands.
Closing costs vary depending on where you live: They can be anywhere from 2% to 3% of a home’s purchase price and up to 5% to 6% in high-tax areas.
These expenses can add up and typically include discount points you may pay to lower your interest rate, along with an origination fee that generally ranges from 1% to 1.5% of the loan amount.
You’ll also likely see charges for services such as an appraisal, survey, title search, title insurance, deed and mortgage recording, transfer taxes and attorney fees. If your lender requires an escrow account, the estimate will also include projected monthly costs for property taxes and homeowners' insurance.
Applying for a mortgage can feel complex, but understanding each step from preparing your finances to reviewing final closing documents can make the process more manageable. Staying organized, responding quickly to lender requests and carefully reviewing loan details can help prevent delays and unexpected costs. With preparation and attention to detail, borrowers can move through the process with greater confidence as they work toward closing on their new home.
