Getting a mortgage starts well before you tour homes. You need to understand what you can afford, gather financial documents, get pre-approved by a lender, and then navigate the process from application through closing. The whole journey from first steps to getting your keys typically takes a few months, and knowing what to expect at each stage keeps things moving smoothly.
Check Your Financial Standing First
Before you contact a lender, take stock of three things: your credit score, your debt-to-income ratio, and your savings. These three numbers largely determine whether you qualify and what interest rate you’ll get.
Your credit score sets the floor. Conventional loans require a minimum 620 credit score. FHA loans, which are backed by the Federal Housing Administration, allow scores as low as 580 with a 3.5% down payment, or as low as 500 if you put down 10%. A higher score won’t just help you qualify; it typically earns you a lower interest rate, which saves thousands over the life of the loan.
Your debt-to-income ratio (DTI) measures how much of your gross monthly income goes toward debt payments, including the future mortgage. Conventional lenders prefer a DTI of 45% or below, though borrowers with strong credit and cash reserves sometimes get approved up to 50%. FHA loans cap DTI at 43% in most cases. To calculate yours, add up all your monthly debt obligations (car payments, student loans, credit card minimums, and the estimated mortgage payment) and divide by your gross monthly income.
Your savings matter for two reasons: the down payment and the reserves. Lenders want to see that you have several months’ worth of mortgage payments sitting in your accounts as an emergency cushion, on top of whatever you plan to put down.
Understand Your Loan Options
There are four main types of home loans, each with different down payment requirements and eligibility rules. Picking the right one can save you a significant amount of money.
- Conventional loans are not backed by the government and are the most common type. The minimum down payment is 3%, but anything under 20% means you’ll pay private mortgage insurance (PMI), a monthly fee that protects the lender if you default. PMI typically drops off once you reach 20% equity in the home.
- FHA loans are insured by the Federal Housing Administration and are designed for borrowers with lower credit scores or smaller down payments. The minimum down payment is 3.5% with a 580 credit score. FHA loans come with their own mortgage insurance premiums, which can last the life of the loan depending on your down payment amount.
- VA loans are available to military veterans, active-duty service members, and eligible spouses. They require no down payment and have no minimum credit score set by the VA, though individual lenders may set their own thresholds. You’ll need a Certificate of Eligibility from the VA to apply.
- USDA loans are backed by the U.S. Department of Agriculture for buyers in eligible rural areas. They offer zero down payment, but you must fall below the income threshold set for your community. Most lenders look for a credit score of at least 640.
Gather Your Documents
Mortgage applications are paper-intensive. Having everything ready before you apply prevents delays. Here’s what lenders typically ask for:
- Tax returns: one to two years’ worth. You’ll likely sign a Form 4506-T, which lets the lender verify your returns directly with the IRS.
- Pay stubs: usually from the past 30 to 60 days, plus W-2 forms from the past two years.
- Other income documentation: if you receive income from a business, side gig, rental property, Social Security, child support, or investments, bring 1099 forms, direct deposit records, or other proof.
- Bank and investment statements: the most recent two to three months of checking, savings, and investment account statements, including retirement accounts.
- Photo ID: a driver’s license or passport.
- Rental history: some lenders ask for 12 months of canceled rent checks or a letter from your landlord confirming on-time payments.
- Gift letters: if a family member is helping with your down payment, you’ll need a signed letter stating the amount, the relationship, the date you received the money, and a clear statement that repayment is not expected.
Get Pre-Approved
Pre-approval is when a lender reviews your finances and tells you how much they’re willing to lend. It’s not a guarantee of a loan, but it carries far more weight than a basic pre-qualification, which is usually just a rough estimate based on self-reported numbers. Sellers and their agents take pre-approved buyers more seriously because it shows a lender has already vetted your income, assets, and credit.
During pre-approval, the lender pulls your credit report and reviews the documents listed above. You’ll receive a pre-approval letter stating the loan amount you qualify for. That letter is typically valid for 60 to 90 days, so time your application close to when you plan to start house hunting.
It’s worth getting pre-approved by two or three lenders. Each will offer slightly different rates and terms, and comparing them gives you leverage. Multiple mortgage inquiries within a short window (generally 14 to 45 days, depending on the scoring model) count as a single inquiry on your credit report, so shopping around won’t hurt your score.
Make an Offer and Apply Formally
Once you find a home and your offer is accepted, you formally apply for the mortgage with your chosen lender. Within three business days of receiving your application, the lender must provide a Loan Estimate. This standardized document breaks down your loan terms, estimated monthly payment, interest rate, and all projected closing costs. Every lender uses the same format, which makes comparing offers straightforward if you’re still considering multiple lenders at this stage.
This is also when you can lock in your interest rate. A rate lock is a written guarantee from the lender that your rate won’t change for a set period, usually 30 to 60 days, while the loan is processed. Some lenders charge a fee for the lock, especially for longer lock periods, so ask about this upfront. If rates are rising, locking in early protects you. If rates are falling, some lenders offer a “float-down” option that lets you take advantage of a rate drop.
What Happens During Underwriting
After you apply, the loan goes to underwriting. This is the lender’s deep review of your financial profile and the property itself. The underwriter verifies everything you submitted, confirms your employment, and orders a home appraisal to make sure the property is worth the amount you’re borrowing.
Underwriting typically takes two to four weeks, but it can stretch longer if the underwriter needs additional documentation. You might be asked for updated bank statements, explanations for large deposits, or letters from employers. Respond quickly to these requests; delays here push back your closing date. Avoid making major financial moves during this period. Taking on new debt, switching jobs, or making large purchases can change your DTI or raise red flags that slow or derail the process.
Closing Costs and What You’ll Pay
Closing costs are the fees you pay to finalize the loan, and they typically run 3% to 5% of the loan amount. On a $300,000 mortgage, that’s $9,000 to $15,000. These costs are separate from your down payment and are usually due at closing, though some lenders let you roll them into the loan balance.
Here’s what’s typically included:
- Origination fee: the lender’s charge for processing the loan, often around 1% of the loan amount.
- Points: optional upfront fees you can pay to lower your interest rate. One point equals 1% of the loan amount and typically reduces your rate by a fraction of a percent. Paying points makes sense if you plan to stay in the home long enough for the monthly savings to exceed the upfront cost.
- Appraisal fee: covers the professional assessment of the home’s market value.
- Title search and insurance: protects against ownership disputes on the property.
- Credit report fee, attorney fees, and inspection fees.
- Prepaid interest: covers the interest that accrues between your closing date and the end of that month.
- Escrow deposit: an upfront fund, usually covering a couple months of property taxes and homeowners insurance, that the lender holds to pay those bills on your behalf going forward.
A few days before closing, you’ll receive a Closing Disclosure that shows your final costs. Compare it line by line with the Loan Estimate you received earlier. Significant discrepancies are rare, but you have the right to question anything that changed.
Closing Day
Closing is the final step. You’ll sign a stack of documents, provide your down payment and closing costs (typically via cashier’s check or wire transfer), and officially take ownership of the property. The whole appointment usually takes one to two hours. Bring your photo ID and any remaining documents your lender requested.
After closing, the lender funds the loan, the title transfers to your name, and you get the keys. Your first mortgage payment is generally due the first of the month following a full month after closing. If you close on March 15, for example, your first payment would typically be due May 1, since the prepaid interest you paid at closing covers the rest of March.
How Long the Whole Process Takes
From pre-approval to closing, expect roughly 30 to 60 days once you have an accepted offer. The pre-approval itself can take a few days to a couple of weeks depending on how quickly you provide documents. The time you spend house hunting is entirely variable. All told, most buyers spend two to four months from their first lender conversation to moving day, though it can be faster or slower depending on your local market and how smoothly underwriting goes.
