What You Need to Know About Credit Scores

Your credit score is one of the most important factors in mortgage qualification. Understanding how credit scores work, what affects them, and how lenders use them can help you make informed decisions about your Arizona home purchase.

This comprehensive guide demystifies credit scores and provides actionable strategies for Arizona homebuyers at every credit level.

Credit Score Basics

What is a Credit Score?

A credit score is a three-digit number (typically ranging from 300 to 850) that represents your creditworthiness based on your credit history. Lenders use this number to predict how likely you are to repay borrowed money.

Key Points:

  • Credit scores are calculated by credit bureaus using mathematical models
  • The most common model used by mortgage lenders is the FICO Score
  • You have multiple credit scores - one from each bureau (Experian, Equifax, TransUnion)
  • Scores can vary between bureaus based on the information they have
  • Lenders typically use your middle score for mortgage qualification

FICO vs VantageScore

While you may see VantageScores on free credit monitoring sites, mortgage lenders use FICO scores. These scoring models can produce different results, so always check your FICO scores when preparing to buy a home. Learn more at myFICO.com.

The 5 Factors That Determine Your Credit Score

35%

1. Payment History

The most important factor - whether you pay your bills on time.

✓ Positive Factors:

  • • Paying all bills on time every month
  • • No late payments in recent history
  • • Consistent payment patterns
  • • Successfully managing multiple accounts

✗ Negative Factors:

  • • Payments 30+ days late
  • • Collections or charge-offs
  • • Bankruptcy or foreclosure
  • • Public records (liens, judgments)

Tip: Set up automatic payments or payment reminders. Even one 30-day late payment can drop your score by 60-110 points.

2. Credit Utilization (Amounts Owed)

How much of your available credit you're using, especially on revolving accounts like credit cards.

Utilization Impact:

0-10% Utilization Excellent
10-30% Utilization Good
30-50% Utilization Fair
50%+ Utilization Poor

Quick Win: Paying down credit card balances can improve your score within 30 days. Aim to keep utilization below 30%, ideally under 10%.

3. Length of Credit History

How long you've had credit accounts open and active.

This factor considers:

  • Age of your oldest account
  • Age of your newest account
  • Average age of all accounts
  • How long specific types of accounts have been open
  • How long since you've used certain accounts

Important: Don't close old credit cards even if you're not using them. Keep them open to maintain your credit history length.

Common Credit Score Myths Debunked

❌ MYTH: Checking your credit hurts your score

✓ TRUTH: Checking your own credit is a "soft inquiry" and does NOT affect your score. Check as often as you want!

❌ MYTH: Closing credit cards improves your score

✓ TRUTH: Closing cards can hurt your score by reducing available credit and shortening credit history. Keep old cards open.

❌ MYTH: Paying off collections removes them from your report

✓ TRUTH: Paid collections still show on your report for 7 years, though they may impact your score less than unpaid ones.

❌ MYTH: You need perfect credit to buy a home

✓ TRUTH: FHA loans accept scores as low as 500-580. Perfect credit is not required!

❌ MYTH: Income affects your credit score

✓ TRUTH: Your income is NOT part of your credit score calculation. Scores are based solely on credit history.
