Your credit score is one of the most important factors deciding whether you get approved for a home loan and at what interest rate. Many Vietnamese families in the US pay in cash or rarely use credit cards, so their credit file is thin or lower than it needs to be. The good news is that in about six months you can meaningfully raise your score if you do the right things.
How a credit score is calculated
Most scoring models (like FICO) rest on five main groups:
- Payment history (about 35%): whether you pay on time.
- Credit utilization (about 30%): your balances versus your card limits.
- Length of credit history (about 15%): how long your accounts have been open.
- Credit mix (about 10%): variety among cards, auto loans, and other credit.
- New credit (about 10%): how many new accounts you have opened recently.
Months 1 to 2: Review and clean up
Pull your free credit reports from all three bureaus (Equifax, Experian, TransUnion). Check every line carefully: any debt that is not yours, any closed account still listed as open, any wrong late-payment dates. Errors are common, and you have the right to dispute them for free. Fixing a single error can sometimes lift your score by dozens of points.
Months 2 to 4: Lower your utilization
This is the fastest lever. Try to keep each card balance below 30% of its limit, and ideally under 10%. For example, on a card with a $10,000 limit, aim to keep the balance under $1,000 to $3,000. You can pay it down before the statement date, because the number reported to the bureaus is the balance on that date, not the due date. Do not close old cards, since that lowers your total available credit and shortens your history.
Months 1 to 6: Pay on time, every time
A single 30-day late payment can pull your score down sharply. Set up autopay for at least the minimum on every account. If you have been late before, the impact fades over time, so start rebuilding today.
Extra tips for a thin credit file
- Ask a relative with strong credit to add you as an authorized user on their card.
- Consider a secured credit card if you have no cards yet.
- Avoid opening several new accounts right before applying, since each hard inquiry dings your score a little.
What NOT to do before applying
During the six months of preparation, do not finance a car, do not open a new card for a sign-up offer, and do not switch jobs right before you apply if you can avoid it. Lenders look at your whole stability picture, not just the score number.
