Getting a loan to buy a house starts with understanding your finances, choosing the right loan type, getting pre-approved by a lender, and then completing a full application once you find a home. The entire process typically takes 30 to 60 days from application to closing, though preparation should begin months earlier. Here’s how each stage works and what you’ll need along the way.
Check Your Credit and Finances First
Before you talk to any lender, pull your credit report and check your score. Your credit score determines which loan programs you qualify for and directly affects the interest rate you’ll be offered. For a conventional loan, you’ll need at least a 620 credit score. FHA loans allow scores as low as 580 with a 3.5% down payment, or 500 if you can put 10% down. VA and USDA loans don’t set official minimums, but most lenders want to see at least a 620 to 640 score.
Lenders also look at your debt-to-income ratio, or DTI. That’s your total monthly debt payments (car loans, student loans, credit cards, plus the future mortgage payment) divided by your gross monthly income. Conventional lenders prefer a DTI of 45% or lower, though borrowers with strong credit and cash reserves may qualify with up to 50%. FHA loans cap DTI at 43%, while VA and USDA loans generally allow up to 41%. If your DTI is too high, paying down existing debt before applying can make a real difference.
Choose the Right Loan Type
There are four main mortgage programs, each designed for different situations. Picking the right one can save you thousands of dollars over the life of your loan.
- Conventional loans are the most common option. The minimum down payment is 3%, but anything under 20% means you’ll pay private mortgage insurance (PMI), an extra monthly fee that protects the lender if you default. Once you build 20% equity in the home, you can request to drop PMI. You’ll need a 620 credit score at minimum.
- FHA loans are backed by the Federal Housing Administration and are popular with first-time buyers or anyone with a lower credit score. The 3.5% down payment requirement is manageable, but FHA loans come with their own mortgage insurance premiums that last for the life of the loan in most cases.
- VA loans are available to military veterans, active-duty service members, and eligible spouses. They require no down payment and have no official minimum credit score. You’ll need a Certificate of Eligibility from the VA to apply.
- USDA loans are designed for buyers in eligible rural and suburban areas who fall below a set income threshold for their community. Like VA loans, they require no down payment. Most lenders look for a credit score of at least 640.
Get Pre-Approved
Pre-approval is different from pre-qualification. Pre-qualification is a quick, informal estimate of what you might borrow. Pre-approval is a formal process where the lender verifies your income, assets, and credit, then issues a letter stating the loan amount you’re approved for. Sellers take pre-approved buyers much more seriously because it shows you’ve already been vetted financially.
A pre-approval letter is typically good for 60 to 90 days, giving you a window to find a home and make an offer. If you don’t find one in time, you can usually get the letter renewed, though the lender may re-check your finances. It’s worth shopping with two or three lenders during this stage. Each one may offer different rates and fees, and comparing them can save you a significant amount over a 15- or 30-year loan. Multiple mortgage inquiries within a short window (usually 14 to 45 days, depending on the scoring model) count as a single inquiry on your credit report.
Gather Your Documents
Once you’re ready to move forward, lenders will ask for documentation to verify everything on your application. Having these ready speeds up the process considerably:
- Proof of income: Recent pay stubs (usually the last 30 days) and W-2 forms from the past two years.
- Tax returns: Most lenders want your last two years of federal returns. Self-employed borrowers will also need business tax returns (such as a 1120, 1120S, or Schedule K-1) and a year-to-date profit-and-loss statement if more than three months have passed since the last tax year ended.
- Bank and asset statements: Recent statements from checking, savings, and investment accounts showing you have funds for the down payment and reserves.
- Debt information: Details on any outstanding loans, credit cards, or other obligations.
- Identification: Your Social Security number, government-issued ID, and current address.
The lender may request additional documents during the process. Responding quickly keeps things on track.
Submit Your Full Application
After your offer on a home is accepted, you’ll submit a complete mortgage application to your chosen lender. This includes all the documentation above plus details about the property itself, such as the address, purchase price, and the terms of your sales contract. The lender uses this information to begin underwriting, which is their deep review of whether the loan is a sound risk.
During underwriting, two things happen simultaneously. First, the lender orders an appraisal, where a licensed appraiser visits the property and determines its market value. The lender needs to confirm that the home is worth at least what you’re paying for it, since the property serves as collateral for the loan. If the appraisal comes in low, you may need to renegotiate the purchase price, make up the difference in cash, or walk away.
Second, the lender conducts a title search to verify that the seller legally owns the property and that there are no outstanding liens, disputes, or claims against it. This protects you from inheriting someone else’s legal problems.
What Happens at Closing
Once underwriting is complete and everything checks out, you’ll receive a final approval. Your lender will send a Closing Disclosure at least three business days before your closing date. This document lays out every cost associated with the loan: your interest rate, monthly payment, and all closing fees. Compare it carefully to the Loan Estimate you received earlier in the process to make sure nothing changed unexpectedly.
Closing costs typically run 3% to 5% of your loan amount. On a $300,000 loan, that’s $9,000 to $15,000. These costs include lender origination fees, the appraisal fee, title insurance, prepaid property taxes and homeowners insurance, and any discount points you’re buying to lower your rate. Some of these costs are negotiable, and in some cases sellers agree to cover a portion of closing costs as part of the deal.
At closing, you’ll sign the final loan documents, provide a cashier’s check or wire transfer for your down payment and closing costs, and receive the keys. The lender funds the loan, the title transfers to your name, and you officially own the home.
How Long the Process Takes
From the day you submit your full application to closing day, expect roughly 30 to 45 days for a conventional loan. FHA and VA loans sometimes take slightly longer due to additional requirements. The biggest delays usually come from missing documents, appraisal issues, or title complications. Staying responsive to your lender’s requests and avoiding major financial changes during this period (opening new credit cards, switching jobs, making large purchases) helps keep the timeline on track.
The preparation phase, including improving your credit, saving for a down payment, and getting pre-approved, can take anywhere from a few weeks to several months depending on where you’re starting from. Buyers who lay that groundwork before house hunting tend to have a much smoother experience once they find the right home.
