Key Takeaways

  • FICO scores range from 300-850 and are used by 90% of top lenders; mortgage lenders typically use the middle score of three bureau scores
  • Payment history accounts for 35% of FICO score, amounts owed 30%, length of credit history 15%, credit mix 10%, and new credit 10%
  • Most conventional loans require minimum 620 FICO score, FHA requires 580 (3.5% down) or 500 (10% down), while VA and USDA have no statutory minimum
  • Credit reports contain four sections: identifying information, credit accounts (tradelines), public records, and inquiries (hard and soft)
  • Major derogatory marks include bankruptcies (7-10 years on report), foreclosures (7 years), collections, charge-offs, and judgments
  • Credit utilization ratio (balances vs. limits) should ideally be under 30% for optimal scoring; high utilization significantly lowers scores

Credit Analysis

Credit analysis is a fundamental component of mortgage underwriting. Understanding how credit scores work, what credit reports contain, and how to interpret credit data is essential for MLOs.

Credit Scores Overview

A credit score is a three-digit number that represents a borrower's creditworthiness based on their credit history.

FICO Score Basics

FactorDetails
Score Range300-850
DeveloperFair Isaac Corporation (FICO)
UsageUsed by 90% of top lenders
Mortgage VersionFICO Score 2, 4, 5 (varies by bureau)

How Mortgage Lenders Use Scores

When a borrower applies for a mortgage, lenders pull credit from all three bureaus:

BureauFICO Version for Mortgages
ExperianFICO Score 2
EquifaxFICO Score 5
TransUnionFICO Score 4

The Middle Score Rule: Lenders use the middle score of the three. If there are only two scores, the lower one is used.

Score Examples

ExperianEquifaxTransUnionScore Used
720705730720 (middle)
680710695695 (middle)
650670--650 (lower of two)

FICO Score Components

FICO scores are calculated based on five weighted categories:

The Five Factors

FactorWeightDescription
Payment History35%On-time vs. late payments
Amounts Owed30%Credit utilization, balances
Length of Credit History15%Age of accounts
Credit Mix10%Types of credit used
New Credit10%Recent accounts, inquiries

Payment History (35%)

The most important factor. Includes:

  • On-time payment record
  • Late payments (30, 60, 90, 120+ days)
  • Collections, charge-offs, bankruptcies
  • Public records (judgments, liens)

Impact of Late Payments:

SeverityScore Impact

60 days late70-135 points
90+ days late80-150+ points
Collection/Charge-off100-150+ points

Amounts Owed (30%)

ComponentIdeal Range
Credit utilization ratioBelow 30%
Number of accounts with balancesFewer is better
Installment loan balancesProgress on paying down

Credit Utilization Example:

Length of Credit History (15%)

FactorWhat It Measures
Age of oldest accountLonger is better
Average age of accountsOlder average is better
Age of newest accountVery new accounts can lower average

Credit Mix (10%)

Having a variety of credit types can help:

  • Revolving credit (credit cards)
  • Installment loans (auto, personal, student)
  • Mortgage loans
  • Retail accounts

New Credit (10%)

FactorImpact
Hard inquiriesEach can lower score 5-10 points
Multiple inquiries (mortgage shopping)Treated as one within 45 days
New accounts openedMultiple new accounts = higher risk

Credit Report Components

A credit report contains several sections that underwriters review.

Four Main Sections

SectionContents
Identifying InformationName, SSN, DOB, addresses, employers
Credit Accounts (Tradelines)All credit accounts and history
Public RecordsBankruptcies, judgments, liens
InquiriesHard and soft credit pulls

Understanding Tradelines

Each credit account (tradeline) shows:

Data PointInformation
CreditorName of lender/creditor
Account NumberPartial number for identification
Account TypeRevolving, installment, mortgage
Date OpenedWhen account was established
Credit Limit/AmountOriginal loan or credit limit
Current BalanceAmount currently owed
Payment StatusCurrent, 30/60/90 days late
Payment History24-84 months of payment data

Tradeline Status Codes

StatusMeaning
OpenAccount is active
ClosedAccount is closed
PaidInstallment loan fully paid
CollectionAccount sold to collection agency
Charge-offCreditor wrote off as loss

Derogatory Credit Items

Derogatory marks significantly impact credit scores and mortgage approval.

Types of Derogatory Marks

Collections7 years from first delinquencySevere
Charge-offs7 years from first delinquencySevere

Waiting Periods After Major Events

EventConventionalFHAVA
Chapter 7 Bankruptcy4 years2 years2 years
Chapter 13 Bankruptcy2 years from discharge1 year with court approval1 year
Foreclosure7 years3 years2 years
Short Sale4 years3 years2 years

Credit Inquiries

Hard vs. Soft Inquiries

TypeImpactExamples
Hard InquiryCan lower score 5-10 pointsLoan applications, credit cards
Soft InquiryNo score impactPre-approvals, employment checks, self-checks

Rate Shopping Protection

When shopping for a mortgage, multiple inquiries within a 45-day window are treated as a single inquiry. This allows borrowers to compare lenders without damaging their credit.


Credit Improvement Strategies

MLOs should understand how borrowers can improve their credit.

Quick Improvements (Days to Weeks)

ActionPotential Impact
Pay down credit cardsReduce utilization, boost score
Become authorized userAdd positive history
Dispute errorsRemove incorrect negatives
Request credit limit increasesLower utilization ratio

Medium-Term Improvements (Months)

ActionPotential Impact
Consistent on-time paymentsBuild payment history
Pay off collectionsRemove or reduce impact
Limit new credit applicationsReduce hard inquiries
Keep old accounts openPreserve credit history length

What NOT to Do Before Applying

  • Open new credit accounts
  • Close old credit accounts
  • Make large purchases on credit
  • Co-sign for others
  • Pay off and close installment loans
  • Ignore collection accounts

Rapid Rescoring

Rapid rescoring is a process that allows quick updates to credit reports during a mortgage application.

How It Works

  1. Borrower takes specific action (pays down card, corrects error)
  2. Lender requests updated report from credit bureaus
  3. Score is recalculated with new information
  4. Process takes 3-5 business days vs. 30+ normally

Common Rapid Rescore Scenarios

ScenarioPotential Score Increase
Pay credit card to 30% utilization20-50 points
Remove erroneous collection50-100+ points
Add authorized user tradeline20-40 points
Correct payment history errorVaries widely
