Why Credit Score Myths Are So Costly for Home Buyers
Misunderstanding how credit works isn't just an inconvenience — for a first-time buyer, it can mean a higher interest rate, a loan denial, or months of unnecessary delay. The homebuying process moves fast once you're ready, and lenders scrutinize credit in ways that differ significantly from what most people assume. Getting familiar with the terminology and concepts involved is one of the smartest early steps you can take.
The myths below are among the most common — and most damaging — we see repeated by first-time buyers. Clearing them up now gives you a more accurate picture of where you stand and what actually moves the needle.
Myth
You need a perfect or near-perfect credit score to buy a home.
Fact
Most loan programs accept scores well below 800, and some government-backed options go as low as 580.
Many first-time buyers delay their search for years, convinced they need an 800+ credit score before a lender will take them seriously. In reality, conventional loans typically require a minimum score around 620, while FHA loans — backed by the Federal Housing Administration — can accept scores as low as 580 with a 3.5% down payment, or even 500 with a larger down payment. A higher score will generally unlock better interest rates, but a score in the mid-600s can still get you to the closing table. Work on improving your score where possible, but don't let perfectionism paralyze your plans.
Myth
Checking your credit score will hurt it.
Fact
Checking your own score is a soft inquiry and has no effect on your credit whatsoever.
This myth keeps many buyers in the dark about where they actually stand. Credit inquiries come in two forms: soft inquiries (like checking your own score or pre-qualification checks) and hard inquiries (when a lender formally reviews your credit for a loan decision). Only hard inquiries can temporarily lower your score, and even then the impact is typically small and short-lived. You should be monitoring your credit report regularly — you're entitled to free reports from all three major bureaus through AnnualCreditReport.com. Knowing your score early gives you time to address any issues before you apply.
Myth
As long as you pay your bills on time, your credit score will be fine.
Fact
Payment history is the largest factor, but credit utilization — how much of your available credit you're using — is nearly as important.
Payment history accounts for roughly 35% of a FICO score, making it the single biggest factor. But credit utilization — the ratio of your current balances to your total credit limits — accounts for about 30%. Carrying balances above 30% of your available credit can measurably drag your score down, even if you've never missed a payment. Before applying for a mortgage, focus on paying down revolving balances like credit cards. Bringing utilization below 10% can meaningfully boost your score in one to two billing cycles.

Myth
Shopping multiple lenders will tank your credit score.
Fact
Most credit scoring models treat multiple mortgage inquiries within a short window as a single hard inquiry.
This fear stops buyers from comparison-shopping — which is exactly what they should be doing. FICO and VantageScore both recognize that a borrower applying to several mortgage lenders in a short period is rate shopping, not accumulating debt. Depending on the scoring model used, that window is typically 14 to 45 days. Multiple mortgage inquiries within that period are generally grouped and counted as one. Don't let concern about a few points discourage you from finding the most favorable loan terms available to you.
Myth
Closing old credit card accounts will improve your score before applying.
Fact
Closing accounts typically reduces your available credit, raises your utilization ratio, and can shorten your credit history — all of which may lower your score.
It feels tidy to close accounts you're not using, but doing so before a mortgage application can backfire. When you close a credit card, its credit limit is removed from your total available credit. If you're carrying any balances elsewhere, your utilization ratio immediately rises. Additionally, older accounts contribute positively to the length of your credit history, which makes up about 15% of your FICO score. Unless an account carries a fee that isn't worth paying, leave it open — especially in the months leading up to your application. You can read more about credit score myths that quietly hurt your financial decisions to avoid similar traps.
Myth
Your credit report is accurate, so there's nothing to check.
Fact
Studies suggest a significant portion of credit reports contain errors, some serious enough to affect loan eligibility.
A Federal Trade Commission study found that roughly one in five consumers had an error on at least one of their three credit reports. These errors range from minor clerical mistakes to serious issues like accounts that don't belong to you or incorrect delinquency records. Any inaccuracy that lowers your score could cost you a better interest rate — or disqualify you altogether. Pull your reports well before you plan to apply, review each one carefully, and dispute any errors promptly. The process takes time, so don't wait until you're under contract. Disputing a credit report error is more straightforward than most people expect when you follow the right channels.
What to Do With This Information Before You Apply
Credit readiness isn't a checkbox — it's an ongoing condition. The period six to twelve months before you apply for a mortgage is when small, deliberate habits have the biggest impact. Keep balances low on revolving accounts, avoid opening new lines of credit unnecessarily, and resist the urge to close accounts you've held for years.
Most importantly, pull your credit reports from all three major bureaus and read them carefully. If you find errors — and there's a reasonable chance you will — start the dispute process immediately. Corrections can take 30 to 60 days to resolve, and you want that resolved before a lender runs a hard inquiry on your file.
Financing surprises are one of the most common reasons deals fall apart. Understanding your credit picture thoroughly before making an offer dramatically reduces that risk.
