Buying your first home is one of the largest financial decisions you will make. The process involves more steps, more paperwork, and more moving parts than most first-time buyers expect. This guide walks through every major stage -- from understanding your credit to signing at the closing table -- so you know exactly what to expect and how to prepare.
Step 1: Understand your financial baseline
Before you speak to a lender, get a clear picture of where you stand financially. Lenders evaluate three things above all else: your credit score, your debt-to-income (DTI) ratio, and your available assets for a down payment and closing costs.
Credit score: Most conventional loans require a minimum score of 620. FHA loans allow scores as low as 580 with a 3.5% down payment, or 500 with 10% down. The higher your score, the lower your interest rate -- even a 40-point difference between 680 and 720 can save tens of thousands of dollars over a 30-year loan. Pull your free credit report from AnnualCreditReport.com and dispute any errors before applying.
Debt-to-income ratio: Your DTI is the percentage of your gross monthly income that goes toward debt payments. Most lenders cap total housing costs (including principal, interest, taxes, and insurance) at 28% of gross income, and total debt obligations at 43%. Fannie Mae's Desktop Underwriter may approve DTIs up to 50% for borrowers with strong compensating factors such as significant reserves or a high credit score.
Down payment and reserves: You need money for the down payment, closing costs (typically 2--5% of the loan amount), and post-closing reserves. Some loan programs allow gifts from family members for the down payment -- ask your lender which programs permit this and what documentation is required.
Step 2: Choose the right loan program
First-time buyers have access to several loan programs with lower down payment requirements than standard conventional loans.
Conventional loans (Fannie Mae / Freddie Mac): Down payments as low as 3% for qualified first-time buyers through programs like Fannie Mae's HomeReady and Freddie Mac's Home Possible. Private mortgage insurance (PMI) is required when the down payment is below 20%, but cancels automatically once you reach 20% equity. Conforming loan limits for 2026 are set by the Federal Housing Finance Agency (FHFA) and vary by county.
FHA loans (Federal Housing Administration): The most common first-time buyer loan. Requires just 3.5% down with a credit score of 580 or higher. FHA mortgage insurance premium (MIP) is required for the life of the loan unless you put down 10% or more (in which case it cancels after 11 years). FHA loan limits are set annually by HUD and are lower than conforming limits in most markets.
VA loans (U.S. Department of Veterans Affairs): Available to eligible veterans, active-duty service members, and surviving spouses. No down payment required, no PMI, and competitive interest rates. The VA funding fee can be financed into the loan. VA loans are among the most favorable financing products available to qualifying buyers.
USDA loans: Available for homes in eligible rural and suburban areas. No down payment required. Income limits apply. Property eligibility can be checked at the USDA's online eligibility map.
Step 3: Get pre-approved before you shop
A pre-approval letter tells sellers you are a serious, qualified buyer and sets a ceiling on your purchase price. Pre-approval differs from pre-qualification: pre-approval requires a hard credit pull and full documentation review (W-2s, pay stubs, tax returns, bank statements), while pre-qualification is an informal estimate based on self-reported information.
Apply with two or three lenders to compare rates and fees. Multiple mortgage inquiries within a 45-day window count as a single inquiry under FICO scoring rules, so shopping does not materially hurt your credit score. Your pre-approval letter is typically valid for 60--90 days.
Use our Mortgage Calculator to model payment scenarios at different price points and rates before your pre-approval conversation -- it will help you determine what monthly payment fits comfortably in your budget.
Step 4: Make an offer and go under contract
Once you find a home, your real estate agent submits an offer. If accepted, you enter the purchase contract phase. You will typically have 30--45 days to complete financing, inspections, and appraisal before closing.
Your earnest money deposit (typically 1--3% of the purchase price) is held in escrow and applied to your down payment or closing costs at closing. If you back out of the contract without a qualifying contingency, you may forfeit the deposit.
Step 5: Understand your Loan Estimate
Within three business days of submitting a full mortgage application, your lender is required by TILA-RESPA Integrated Disclosure (TRID) rules to provide a Loan Estimate. This standardized document shows your loan amount, interest rate, projected monthly payment, and itemized closing costs.
Pay close attention to Section A (origination charges), Section B (services you cannot shop for), and Section C (services you can shop for -- including title insurance and settlement agents). The interest rate and lender fees in Section A are locked once you issue a rate lock. For a detailed breakdown of every line, see our guide How to Read a Loan Estimate.
Step 6: Complete the appraisal and inspection
Your lender will order an appraisal to confirm the home's market value supports the loan amount. If the appraisal comes in below the purchase price, you can renegotiate, pay the difference in cash, or walk away (if you have an appraisal contingency).
A home inspection -- paid by the buyer, separate from the appraisal -- identifies material defects. This is not required by lenders but is strongly recommended. Common issues include roof condition, HVAC systems, plumbing, electrical, and foundation. Inspection results can be used to renegotiate repairs or credits with the seller.
Step 7: Closing day
At closing, you sign the final loan documents, pay closing costs and the remaining down payment, and receive the keys. Three business days before closing, your lender must provide a Closing Disclosure matching the terms in your Loan Estimate. Review it carefully and flag any discrepancies before signing.
Closing costs for buyers typically total 2--5% of the loan amount and include lender origination fees, title insurance, prepaid interest, property taxes, homeowners insurance escrow, and recording fees. Some sellers agree to contribute to closing costs as part of the purchase negotiation -- ask your agent about seller concessions in your market.
Down payment assistance programs
Most states and many counties offer down payment assistance (DPA) programs for first-time buyers, often structured as forgivable second liens or deferred-payment loans. The U.S. Department of Housing and Urban Development (HUD) maintains a directory of approved housing counseling agencies that can identify programs available in your area. Income and purchase price limits apply to most DPA programs.
