How to Buy a Home in the U.S. — The Entire Process at a Glance

When you set out to buy your first home in the U.S., you're hit with a flood of unfamiliar terms:

Pre-approval, escrow, contingencies, underwriting, closing…

This article lays out the entire process like a single-page map.

Get the big picture first, then dive into the details of each stage in the series articles below.

Key Steps at Each Stage

Preparation (details: ① Preparation)

1. Financial checkup — Review your income, credit score, debts, down payment, and emergency fund, and get familiar with the concept of DTI (debt-to-income ratio). In the U.S., your mortgage limit effectively determines the price range of homes you can buy — so this comes before house hunting, not after.

2. Talking to lenders and getting pre-approved — Compare two or three lenders among banks, credit unions, and mortgage brokers, and get a pre-approval backed by document verification. It carries far more weight than a pre-qualification, which is little more than a verbal estimate.

House Hunting (details: ② House Hunting)

3. Choosing a buyer's agent — Sign a written Buyer Representation Agreement with an agent who represents you and only you. Since 2024, agent compensation is negotiated directly between buyer and agent, though in practice it's still often negotiated so that the seller covers it.

4. Setting your budget — Base your budget not on the maximum amount your lender approves, but on the total monthly housing cost you can comfortably afford: principal and interest + property taxes + insurance + HOA dues + maintenance.

5–6. Searching and touring homes — Search on MLS-powered sites like Zillow and Redfin, then see homes in person at open houses and private showings. Pay close attention to the roof, HVAC, foundation, signs of water damage, and any unpermitted additions.

Under Contract (details: ③ Under Contract)

7–8. Offers and negotiation — Submit a written offer covering the price, earnest money deposit, closing date, and your safety nets as a buyer — the inspection, appraisal, and financing contingencies. The seller can accept, counter, or reject, and beyond price you can also negotiate seller credits, dates, and what's included in the sale.

9. Opening escrow — Once you're under contract, a neutral third party (escrow) holds the money and documents. Unlike in Korea, you never wire funds directly to the seller. During this period, be especially on guard against wire fraud.

Due Diligence (details: ④ Due Diligence)

10. Inspection — A professional inspector evaluates the condition of the home. If problems turn up, you choose between requesting repairs, negotiating a credit, proceeding as-is, or walking away.

11. Appraisal — The lender verifies the value of the collateral. If the appraisal comes in below the purchase price, you face a fork in the road: bring extra cash, renegotiate the price, or — if you have an appraisal contingency — cancel.

12–13. Underwriting and loan approval — The lender's full review leads to conditional approval and then final approval (clear to close). During this window, changing jobs, taking on new financing, or moving large sums of money can sink a loan that was all but done.

Closing (details: ⑤ Closing)

14–16. Final walk-through, closing, and recording — Confirm one last time that the home is in the same condition as when you went under contract, sign the documents, and wire your cash to close. The moment the transfer of title is recorded with the county, you are legally the owner — and you get the keys.

17. After moving in — Transfer utilities, update your address, set up automatic mortgage payments, change the door locks, and make a maintenance plan. Your first mortgage payment is typically due on the 1st of the second month after closing.

How Much Does It All Cost? (Summary)

• Down payment: 3–20%+ of the purchase price (under 20% usually means adding PMI)

• Closing costs: roughly 2–5% of the purchase price (loan fees, title, prepaid taxes and insurance, etc.)

• Costs along the way: inspection $400–700+, appraisal around $500–800

• Cash to Close = down payment + closing costs − earnest money deposit (EMD) − seller credits

• To be truly safe, budget separately for moving, furniture, and an emergency fund on top of all this.

Ten Common First-Time Buyer Mistakes

1. Touring homes before getting pre-approved — You lose out in competitive offers and fall for homes outside your budget.

2. Talking to only one lender — Rates and fees vary by lender. Get Loan Estimates from two or three and compare.

3. Treating your approval limit as your budget — The lender's maximum and what your family can comfortably afford are two different numbers.

4. Pouring every last dollar into the down payment — Closing costs, moving, repairs, and an emergency fund are right behind it.

5. Making big purchases or changing jobs during escrow — A new car, financed furniture, or a job change can sink a loan that was nearly done.

6. Skipping or skimming the inspection — Saving a few hundred dollars can leave you holding a problem worth tens of thousands.

7. Waiving contingencies without understanding them — Some buyers sign away their safety nets to win a bidding war without realizing the risk.

8. Trusting wire instructions that arrive by email — Before sending any money, always call the escrow company directly at a known phone number to verify.

9. Calculating monthly housing costs with only principal and interest — Property taxes, insurance, HOA dues, and maintenance are part of the real burden.

10. Skipping the final walk-through — Problems discovered after closing are far harder to resolve.

Closing Thoughts

Buying a home in the U.S. looks complicated, but once you know the sequence and prepare accordingly, it's more systematic than you'd expect.

Every step exists for a reason, and buyer protections — contingencies, escrow, the inspection, the appraisal — are built in at every turn.

The most important thing is not to start by looking for a house,

but to first find out how much house you can safely afford.
