To prequalify for a home, you provide a lender with basic financial details (income, debts, assets, and credit history), and the lender gives you a letter estimating how much you could borrow. The process is typically quick, often completed online or over the phone in under an hour, and it usually doesn’t affect your credit score. Here’s what you need to know before you start.
What Prequalification Actually Means
A prequalification letter tells you roughly how much a lender is willing to loan you, based on the financial information you report. It’s not a guaranteed loan offer. Think of it as a first-pass estimate that helps you understand your budget before you start touring homes.
Lenders use the terms “prequalification” and “preapproval” inconsistently. Some lenders call it a prequalification when they rely on self-reported numbers without verifying anything. Others use “preapproval” for the same light-touch process. What matters more than the label is whether the lender actually verified your income, pulled your credit report, and reviewed documentation. A letter based on verified information carries more weight with sellers than one based purely on what you told the lender over the phone. When you’re shopping, ask the lender exactly what their process involves rather than relying on the name they give it.
Information You’ll Need to Provide
Prequalification is built on four categories of financial information: income, assets, debts, and credit history. For a basic prequalification, you’re typically reporting these numbers yourself rather than handing over pay stubs and bank statements. Here’s what to have ready:
- Income: Your gross annual salary, any bonuses or commissions, freelance or side income, and other recurring sources like rental income or alimony.
- Assets: Balances in checking and savings accounts, investment accounts, retirement funds, and any other savings you could use toward a down payment or closing costs.
- Debts: Monthly payments on car loans, student loans, credit cards, personal loans, child support, and any other recurring obligations.
- Employment details: Your employer’s name, your job title, and how long you’ve been in your current position.
- Housing plans: The price range you’re considering, the type of property, and the down payment amount you expect to put forward.
Some lenders will also ask for your Social Security number to pull your credit. Others skip that step during prequalification and save it for the formal preapproval stage.
Credit Score Thresholds by Loan Type
Your credit score is one of the biggest factors in whether you qualify and what interest rate you’ll get. The minimum score depends on the type of mortgage you’re pursuing.
For conventional loans, most lenders require a FICO score of at least 620. FHA loans are more flexible: a score of 580 or higher qualifies you for a down payment as low as 3.5%, and some lenders will go as low as 500 if you can put 10% or more down. VA loans (for eligible military members and veterans) have no government-set minimum score, but most lenders want 620 or higher. USDA loans, designed for buyers in eligible rural areas, typically require a score of 580 or above. If you’re looking at a second home or investment property, expect a higher bar, usually between 640 and 680.
During a standard prequalification, the lender typically runs only a soft credit inquiry, which does not affect your credit score. A hard inquiry, the kind that can temporarily lower your score by a few points, happens later during formal preapproval. This means you can prequalify with multiple lenders to compare estimates without worrying about credit damage.
How Debt-to-Income Ratio Affects Your Number
Your debt-to-income ratio (DTI) is the percentage of your gross monthly income that goes toward debt payments. If you earn $6,000 a month before taxes and pay $1,800 in total monthly debts (including the projected mortgage payment), your DTI is 30%. Lenders use this number to gauge whether you can comfortably handle a mortgage on top of your existing obligations.
Conventional loans generally cap DTI at 45%, though some lenders stretch to 50% for borrowers with strong credit or significant savings. FHA loans look at two ratios: a housing expense ratio (your mortgage payment alone) capped around 31%, and a total DTI capped at 43%. Borrowers with credit scores above 580 and other compensating strengths can sometimes qualify with total DTI up to 50%. VA and USDA loans typically max out around 41%, with some flexibility for borrowers who have excellent credit and stable employment.
Before you contact a lender, calculate your own DTI. Add up your minimum monthly debt payments, then divide by your gross monthly income. If you’re above 45%, paying down a credit card balance or car loan before applying can meaningfully increase the amount you prequalify for.
Steps to Prequalify
The process is straightforward. Start by choosing one or more lenders to approach. You can prequalify through banks, credit unions, online lenders, or mortgage brokers. Since prequalification typically uses a soft credit pull, you can shop around freely.
Next, submit your financial information. Many lenders let you do this through an online form in 15 to 30 minutes. Some prefer a phone call. You’ll enter the income, debt, asset, and employment details described above. The lender runs the numbers and, if everything looks reasonable, issues a prequalification letter stating the loan amount you’d likely qualify for.
That letter is your starting point for house hunting. It tells real estate agents and sellers that a lender has at least reviewed your finances at a high level. Keep in mind that a prequalification letter is typically valid for 60 to 90 days, though the exact window varies by lender. If your letter expires before you find a home, you’ll simply need to request an updated one, especially if your income or debts have changed.
Making Your Prequalification More Useful
A basic prequalification is better than nothing, but it’s less persuasive to sellers than a fully verified preapproval. If you’re buying in a competitive market, consider going one step further and providing actual documentation upfront. That means recent pay stubs, W-2s or tax returns from the past two years, bank statements, and identification. When a lender verifies these documents and pulls a hard credit check, the resulting letter carries significantly more credibility.
Also remember that the amount you prequalify for is a ceiling, not a target. Lenders calculate what you can technically afford based on ratios and guidelines. They don’t account for your grocery budget, childcare costs, travel plans, or retirement savings goals. Borrowing the maximum amount a lender offers can leave you stretched thin. Run your own budget with realistic monthly numbers before committing to a price range.
What Prequalification Won’t Tell You
Prequalification gives you a ballpark loan amount, but it doesn’t lock in an interest rate. Rates change daily, and your actual rate depends on your verified credit score, the loan type, your down payment size, and market conditions at the time you formally apply. It also doesn’t guarantee final approval. Once you’re under contract on a home, the lender will verify everything you reported, order an appraisal of the property, and review your finances in detail. If something has changed, like a new car loan or a job switch, the final approval could look different from the prequalification estimate.
Prequalification is the first step in a longer process, but it’s a valuable one. It gives you a realistic sense of your buying power, signals to sellers that you’re a serious buyer, and helps you focus your search on homes you can actually afford.
