Applying for a mortgage can feel intimidating, especially if you’ve never done it before. Getting a home loan is one of the largest financial decisions you can make, so the pressure to get things right the first time is high. Between the paperwork, the jargon, and the sheer size of the financial commitment, it’s easy to feel overwhelmed before you even start.
The good news? The mortgage process is more manageable than it looks once you know how to qualify and what to expect at each step.
This guide walks you through all the requirements, from getting your finances in order through closing day, with a realistic timeline, a document checklist, and a heads-up on what can actually go wrong along the way. By the end, you should feel confident enough to start shopping for lenders and making offers.
At a glance:
- Timeline: 30–45 days from application to closing; 60–90 days if complications arise
- Minimum credit score: 620 for conventional (though Fannie Mae removed its hard floor in Nov. 2025; most lenders still use 620 as an overlay), 580 for FHA with 3.5% down
- Documents you'll need: Two years of W-2s and tax returns, 30 days of pay stubs, two to three months of bank statements, government-issued ID
- The single biggest money-saving move: Get Loan Estimates from at least three lenders and compare them side by side. Borrowers who shop around can save hundreds of dollars per year on their mortgage payments
- Current rates: 30-year fixed averaging 6.30% as of April 17, 2026 (Freddie Mac PMMS)
Get your finances in order before you apply
Before you do anything else, you need to take an honest look at your financial picture. Lenders evaluate three main areas when deciding whether to approve your application, and the stronger you are in each, the better your rate and terms will be.
Credit score
Check your credit score with all three major reporting agencies (Equifax, Experian, and TransUnion), and dispute any errors you find. You can pull free reports once a year at AnnualCreditReport.com. Avoid opening new credit accounts while you’re preparing to apply. That includes store credit cards, auto loans, and personal loans.
There is no official minimum credit score to apply for a conventional loan, but most lenders like to see at least 620 for a conventional loan, and FHA loans accept scores as low as 580 with 3.5% down.[1] But the real magic number is 740+; that’s where you’ll qualify for the best rates.
Even a difference of 20–40 points can save you thousands of dollars over the life of your mortgage loan. On a $400,000 mortgage, the rate difference between a 700 and a 740 credit score could mean roughly $100 more per month, or more than $36,000 across a 30-year term, based on Freddie Mac’s loan-level pricing adjustments.[2]
Debt-to-income ratio
Your debt-to-income (DTI) ratio measures how much of your gross monthly income goes toward debt payments. To calculate it, add up all your monthly obligations — student loans, car payments, credit card minimums, and your projected mortgage payment — then divide by your gross monthly income.
Most lenders want to see a DTI at or below 43%, though some will go up to 50% if you have compensating factors like a large down payment or significant cash reserves.[1] The CFPB provides a helpful breakdown of how DTI thresholds affect your borrowing options.[3]
Savings and reserves
You’ll need funds for three things: your down payment, closing costs (typically 2%–6% of the purchase price), and cash reserves. Having two to six months of mortgage payments set aside strengthens your application and shows lenders you can handle a temporary income disruption.
“Three things catch people off guard more than anything else,” says Matt Oetting, Executive Loan Officer at Best Interest Financial. “First, paying off too much debt right before applying — it sounds smart, but wiping out your savings to zero out a credit card can leave you without the assets needed to qualify. Second, assuming a new job disqualifies you. Many loan programs work just fine with recent employment, especially if you’re in the same field. Third, taking a ‘no’ from one lender as the final answer.”
Get preapproved (not just prequalified)
Many first-time buyers use “prequalification” and “preapproval” interchangeably, but they’re very different:
- Prequalification: A quick, informal estimate of your borrowing power based on self-reported information. It involves a soft credit check and is non-binding. Think of it as a ballpark.
- Preapproval: A formal, verified assessment of your finances. The lender pulls your credit (hard inquiry), reviews your documentation, and issues a conditional commitment letter. This is what sellers and their agents actually take seriously.
To start the preapproval process, you’ll provide six key data points to the lender: your name, income, Social Security number, the property address (or an estimate), estimated property value, and desired loan amount.[4] The lender must send you a Loan Estimate within three business days of receiving these, per CFPB rules.
You’ll also need to submit supporting documents: two years of W-2s and tax returns, 30 days of recent pay stubs, two to three months of bank statements, and a government-issued ID. Self-employed borrowers should also have two years of business tax returns and a profit-and-loss statement ready.
A preapproval letter is typically valid for 60–90 days. If it expires before you find a home, you’ll need to reapply — the lender will want to reverify your financial picture.
Choose a loan type and lender
The right loan type depends on your credit profile, down payment, and eligibility. Here’s how the four main options break down:
- Conventional (conforming): The most common type. Requires a 620+ credit score and 3%–20% down. The 2026 conforming loan limit is $832,750 in most areas.[5] If you put less than 20% down, you’ll pay private mortgage insurance (PMI) — but unlike FHA loans, PMI drops off once you reach 20% equity.
- FHA: Backed by the Federal Housing Administration. Accepts credit scores as low as 580 with 3.5% down (or 500 with 10% down), per HUD’s FHA loan requirements. The trade-off is that FHA loans require a mortgage insurance premium (MIP) for the life of the loan — you can’t drop it at an equity threshold the way you can with conventional PMI.[6]
- VA: Available to eligible veterans, active-duty service members, and surviving spouses. Offers 0% down and no private mortgage insurance (VA home loan overview). The VA doesn’t set a minimum credit score, though most lenders use 620 as their internal floor.[7]
- USDA: Designed for properties in eligible rural areas. Offers 0% down for borrowers who meet USDA income limits.[8]
The right loan type depends on your credit profile, down payment, and eligibility. Here's how the four main options compare:
| Conventional | FHA | VA | USDA | |
|---|---|---|---|---|
| Best for | Borrowers with strong credit and savings | Buyers with lower credit scores or smaller down payments | Eligible veterans, active-duty service members, and surviving spouses | Buyers in eligible rural areas who meet income limits |
| Min. credit score | 620 (most lenders) | 580 with 3.5% down; 500 with 10% down | No VA minimum; most lenders use 620 | No USDA minimum; most lenders use 640 |
| Down payment | 3%–20% | 3.5%–10% | 0% | 0% |
| 2026 loan limit | $832,750 (most areas) | Varies by county (check HUD limits) | No limit (as of 2020 for full-entitlement borrowers) | No set limit (income-based eligibility) |
| Mortgage insurance | PMI required below 20% down — drops off at 20% equity | Upfront MIP (1.75%) + annual MIP for the life of the loan with less than 10% down; 11 years with 10%+ down | None | Upfront guarantee fee (1%) + annual fee (0.35%) |
| Key trade-off | Best rates and PMI flexibility, but higher credit and down payment bar | Easier to qualify, but MIP is harder to shed | No down payment or PMI, but eligibility is limited to military service |
Whichever type you qualify for, shop at least three lenders and compare their Loan Estimates side by side. Look at the rate, fees, and APR, not just the monthly payment.
A CFPB study found that borrowers who obtained at least two additional quotes saved an average of $600 to $1,200 per year over the life of the loan, and the savings can be dramatically higher depending on loan size and how widely rates vary among lenders.[9] This same principle applies when shopping for home equity loans or home improvement loans.
One thing to keep in mind: multiple mortgage inquiries within a 14–45 day window count as a single hard pull on your credit report, so rate-shopping won’t tank your score.
Matt Oetting recommends looking for a lender “who communicates proactively, has a verifiable track record of closing on time, and actually explains the loan rather than just sending you a pile of paperwork to sign.”
Complete the application and lock your rate
Once you’ve chosen a lender, it’s time to fill out the formal application. Most lenders use the Uniform Residential Loan Application, and most offer the option to apply online.[10] The application itself takes about 20 to 30 minutes.
You’ll submit much of the same information from your preapproval: Social Security number, income verification, assets, and property details. If more than 30 days have passed, expect to provide updated documents.
Once you’re comfortable with the terms, ask your lender to lock your rate. A rate lock keeps your interest rate from rising between the offer and closing. Locks typically last 30 to 60 days, and the lender must provide the terms in writing. With 30-year fixed rates averaging 6.30% as of the week ending April 17, 2026, locking in promptly matters.[11]
What not to do between application and closing
Don’t open any new credit lines — no credit cards, personal loans, or financing. Lenders recheck your credit before closing and can rescind the approval if your profile has changed.
Avoid large purchases or financing; a new car or furniture set can shift your DTI ratio and jeopardize the deal.
Don’t move money between accounts without a paper trail. Unexplained transfers raise red flags for underwriters.
Avoid changing jobs if possible. Lenders generally want to see stable employment. That said, many loan programs work fine with a recent job change if you’re staying in the same field and have at least two years of job history.
What happens during underwriting (and what can go wrong)
“Underwriting” is when the lender’s team verifies everything you’ve submitted: income, credit, assets, and the property’s appraised value. It typically takes two to four weeks within the overall 30–45 day application-to-close timeline.
Lenders also perform underwriting for home equity loans and refinance loans, so this process isn’t unique to purchase mortgages.
Here are the most common problems that derail closings and how to handle them:
- Appraisal comes in low. If the home appraises for less than the purchase price, you have three options: renegotiate the price with the seller, bring extra cash to cover the gap, or walk away from the deal.
- Unexplained deposits. Underwriters flag any large or unusual deposits in your bank accounts. Keep a paper trail for every dollar that moves — a $2,000 birthday check from a family member needs a signed gift letter.
- Job change or new debt. Either of these can kill the deal outright. Lenders recheck employment and credit just before closing.
- Title issues. Liens, boundary disputes, or transfer problems can delay closing, though they’re less common and rarely kill the deal permanently.
Oetting puts it simply: “After years in mortgage lending, I’ve watched pre-approved buyers get denied at the finish line because they made a $2,000 cash deposit they could not source, or they opened a store credit card to buy furniture for the new house.”
The key insight most first-time buyers miss, Oetting adds, is that “underwriters are not looking for perfect credit — they are looking for patterns that predict repayment. A 720 score with three years of stable employment and documented assets beats an 800 score with two months at a new job and a recent $10,000 deposit from a friend.”
Tips for smooth underwriting: Respond to lender requests within 24 hours, don’t make any financial changes, and keep every document organized and accessible.
Close on your home
Once underwriting is complete and your loan is cleared to close, you’ll receive a Closing Disclosure at least three business days before your closing date. This document spells out the final terms of your mortgage: rate, monthly payment, closing costs, and cash due at signing.
Compare the Closing Disclosure line by line against your original Loan Estimate. If you spot discrepancies — especially in fees or the interest rate — flag them with your lender immediately.
At closing, you’ll bring a cashier’s check or arrange a wire transfer to cover your down payment and closing costs. (Some lenders now accept digital payments for portions of closing costs.) You’ll sign the final paperwork, the title transfers, and you’ll get the keys.
One last thing: You’ll need proof of homeowner’s insurance before the lender will fund the loan. Start shopping for a policy around the same time you sign the purchase contract — don’t leave it to the last minute.

FAQ
How long does it take to get a mortgage?
From application to closing, most mortgages take 30–45 days. The timeline can stretch to 60–90 days for new construction or if underwriting complications arise. Getting preapproved before you make an offer helps speed things up, since much of the verification is already done.
What credit score do I need to get a mortgage?
For a conventional loan, most lenders require a minimum of 620. FHA loans accept scores as low as 580 with 3.5% down (or 500 with 10% down). VA and USDA loans have no official minimum, though lenders typically want 620+. Higher scores unlock better rates, and even a modest improvement can save you thousands over 30 years.
Can I apply for a mortgage before finding a house?
Yes — and you should. Getting preapproved before house hunting gives you a realistic budget and makes your offer stronger in competitive markets. Preapproval typically lasts 60–90 days, so time your home search accordingly. You’ll update the application with the property address once you find a home.
What documents do I need to apply for a mortgage?
Most lenders require two years of W-2s and tax returns, 30 days of pay stubs, two to three months of bank statements, and a government-issued ID. Self-employed borrowers also need business tax returns and a profit-and-loss statement. Gathering these before you apply helps avoid delays.
