Buying a first home is a series of decisions, not a single mortgage form. A lender may tell you the maximum it might lend, but only you can decide what monthly payment leaves room for repairs, savings and ordinary life. The Consumer Financial Protection Bureau (CFPB) separates the process into preparing to shop, exploring loan choices, comparing formal offers and closing. That order matters: it gives you time to compare lenders before the pressure of a moving date.

1. Set a payment ceiling before looking at listings

Start with reliable take-home income, existing debts and an emergency reserve. Estimate the full housing cost: mortgage principal and interest, property taxes, homeowners insurance, mortgage insurance when required, homeowners association dues when applicable, utilities and maintenance. Some of these costs may sit outside the amount displayed in a listing or a lender’s principal-and-interest quote. Leave money for moving, closing and repairs. A preapproval amount is a lending limit, not a recommended spending target.

Check your credit reports for errors and review your card and loan balances. Avoid taking on new debt or making unexplained large deposits while preparing to apply; a lender may need to document changes to your finances. A HUD-approved housing counselor can help you review affordability and local down-payment assistance before you commit to a program.

2. Compare the mortgage routes you may qualify for

Conventional loans are one route through private lenders. Down-payment and mortgage-insurance terms vary by product and borrower. FHA-insured loans are made by approved lenders and can allow a down payment as low as 3.5% for eligible borrowers, according to HUD; compare their mortgage-insurance costs with a conventional offer. VA-backed purchase loans may offer eligible service members, veterans and others no down payment when the price does not exceed the appraisal, but the buyer must meet VA and lender requirements and obtain a Certificate of Eligibility. USDA guaranteed loans may allow qualified buyers in eligible rural areas to finance 100% of the purchase through an approved lender, subject to income, property and other rules.

State and local assistance programs may help with the down payment or closing costs. Ask whether assistance is a grant, forgivable loan or repayable second mortgage, and what happens if you sell or refinance. No program is automatically best for every first-time buyer. Ask lenders to price the options you actually qualify for on comparable terms.

3. Gather the records lenders will ask to verify

Expect to document identity, employment and income, assets for the down payment and closing costs, existing debts and the source of any gift funds. Depending on your situation, a lender may request recent pay statements, W-2s or tax returns, bank statements, identification and explanations of unusual deposits. Self-employed applicants may need different records. Ask each lender for its checklist and upload sensitive documents only through a verified lender portal. Never send account numbers to an unverified email address.

4. Get preapproved when you are ready to shop seriously

Contact more than one lender or mortgage broker and ask what it takes to receive a preapproval letter. The lender reviews income, assets, debts and credit and may issue a letter stating a tentative loan amount. The CFPB warns that preapproval is not a guaranteed loan offer, can expire and does not commit you to that lender. Use the letter to support an offer on a home, while keeping your own lower budget ceiling if necessary.

5. Make an offer with the financing timeline in mind

Once you find a home, review the contract’s deposit, financing, appraisal and inspection terms with your real-estate professional or attorney. Contract rules differ by state and deal, so do not assume a contingency protects you unless it is written in the agreement. Schedule an independent home inspection promptly. The inspection assesses the home’s condition for you; an appraisal estimates value for the lender. They answer different questions.

6. Apply to lenders and request comparable Loan Estimates

After identifying a property, give at least three lenders the same purchase price, down payment, loan type and term. A formal mortgage application contains your name, income, Social Security number for a credit report, property address, estimated property value and requested loan amount. For most covered mortgages, the lender must provide a Loan Estimate within three business days after receiving those six pieces of information. You do not need to choose a lender just because it preapproved you.

Compare the Loan Estimates line by line: rate, whether it is locked, annual percentage rate (APR), discount points, lender fees and credits, mortgage insurance, estimated total monthly payment, closing costs and cash to close. Ask what property taxes, insurance and HOA costs were assumed. A lower rate can come with higher upfront points; a lender credit can reduce cash due now but raise the rate. Compare the same loan type and timing, and ask each lender for a revised quote if assumptions differ.

7. Select an offer and respond quickly during underwriting

Tell the lender you choose to proceed, confirm any rate-lock terms and submit the full documentation it requests. Underwriting checks whether your income, debts, assets and property meet the loan’s rules. The lender may request updated statements or explanations; respond accurately and keep copies. It will generally order an appraisal, while you arrange your own inspection. Avoid changing jobs, opening new credit or moving large sums without discussing the effect with your loan officer. A preapproval and a Loan Estimate do not mean the loan has received final approval.

8. Check the final numbers before closing

For most mortgages, you must receive a Closing Disclosure at least three business days before closing. Compare it with the most recent Loan Estimate: loan amount, product, rate, monthly payment, mortgage insurance, taxes and insurance, closing costs and cash to close. If a number or name is wrong, contact the lender or closing agent immediately and ask for an explanation before signing. Arrange homeowners insurance and confirm the exact form of payment needed for closing.

Be alert to mortgage wire fraud. A last-minute email changing payment instructions may be an impersonation attempt. Verify transfer details by calling the closing agent at a number you obtained independently, not one supplied in that email. At closing, read the note, mortgage and deed before signing. Afterward, save the final documents and learn where to make the first payment.
