Key Takeaways

  • Appraisals must be performed by state-licensed or certified appraisers; certified appraisers can appraise any property while licensed appraisers have transaction value limits
  • FIRREA (1989) established appraiser independence requirements and created the Appraisal Subcommittee to oversee state appraiser regulatory programs
  • The Appraiser Independence Requirements (AIR) prohibit loan production staff from selecting, retaining, or influencing appraisers; violations can result in civil penalties
  • Loan-to-Value (LTV) = Loan Amount / Lesser of Purchase Price or Appraised Value; CLTV includes all liens on the property
  • The three approaches to value are Sales Comparison (most common for residential), Cost Approach (new construction), and Income Approach (investment properties)
  • Automated Valuation Models (AVMs) use algorithms and public data for property valuations and are commonly used for HELOCs and refinances with appraisal waivers

Property Valuation

Property valuation determines how much a home is worth, which directly affects loan amounts and risk assessment. Understanding appraisal requirements, independence rules, and valuation methods is essential for MLOs.

Why Property Valuation Matters

Property valuation serves several critical purposes in mortgage lending:

PurposeDescription
LTV CalculationDetermines loan-to-value ratio
Collateral AssessmentEnsures property secures the loan
Risk ManagementPrevents over-lending
Market VerificationConfirms property's market position
Investor RequirementsMeets secondary market standards

Types of Property Valuation

Appraisal Requirements

Who Can Perform Appraisals

Appraisals must be performed by state-licensed or certified appraisers who meet federal qualifications.

CredentialRequirementsLimitations
Licensed AppraiserState-licensed, entry levelTransaction value limits
Certified ResidentialAdditional education/experienceNon-complex 1-4 units
Certified GeneralHighest qualificationAny property type/value

Federally Related Transactions

Appraisals are required for federally related transactions, which include:

  • Loans made by federally regulated institutions
  • Loans sold to Fannie Mae, Freddie Mac
  • FHA, VA, USDA insured/guaranteed loans
  • Loans exceeding de minimis threshold ($400,000 for some)

Appraisal Report Contents

A typical appraisal report includes:

SectionContents
Subject PropertyAddress, legal description, ownership
Neighborhood AnalysisLocation, market conditions, trends
Site DescriptionLot size, zoning, utilities, improvements
ImprovementsStructure details, condition, quality
Comparable SalesRecent similar sales with adjustments
Value ConclusionAppraiser's opinion of value
CertificationAppraiser's statement and signature

Appraiser Independence Requirements

Appraiser independence is critical to prevent fraud and ensure accurate valuations.

FIRREA (1989)

The Financial Institutions Reform, Recovery, and Enforcement Act (FIRREA) established:

  • Federal appraiser qualification standards
  • State licensing/certification requirements
  • Appraisal Subcommittee oversight
  • Independence requirements

Appraiser Independence Requirements (AIR)

Key prohibitions under AIR:

Prohibited ActionDescription
CoercionCannot pressure appraiser for specific value
Selection by ProductionLoan officers cannot select appraisers
Compensation Tied to ValueCannot pay more for higher values
Withholding PaymentCannot refuse to pay for unfavorable results
RetaliationCannot remove from panel for honest work

Who Can and Cannot Select Appraisers

CAN Select AppraisersCANNOT Select Appraisers
Appraisal management company (AMC)Loan officers
Lender's appraisal departmentLoan processors
Correspondent lenderBranch managers
Borrower (with requirements)Real estate agents

Penalties for AIR Violations

  • Civil money penalties up to $25,000 per violation
  • Cease and desist orders
  • Removal from position
  • Potential criminal prosecution

The Three Approaches to Value

Appraisers use three approaches to determine property value:

1. Sales Comparison Approach

The most common method for residential properties. Compares the subject property to recently sold similar properties (comparables or "comps").

ElementDescription
Comparable SelectionSimilar properties sold within 6-12 months
AdjustmentsAdd/subtract for differences
ReconciliationWeight comps to conclude value

Adjustment Examples:

FeatureSubject HasComp HasAdjustment to Comp
Garage2-car1-carAdd value
PoolNoYesSubtract value
Square Feet2,0001,800Add value
Bedrooms43Add value

2. Cost Approach

Calculates what it would cost to rebuild the property minus depreciation. Best for:

  • New construction
  • Unique properties
  • Special-purpose properties

Formula:

Land Value + (Replacement Cost - Depreciation) = Property Value

3. Income Approach

Values property based on the income it generates. Used for:

  • Investment properties
  • Rental properties
  • Commercial real estate

Key Metrics:

MetricFormula
Gross Rent Multiplier (GRM)Sale Price / Annual Gross Rent
Cap RateNet Operating Income / Property Value

Loan-to-Value (LTV) Calculations

LTV is a crucial ratio that measures loan amount against property value.

Basic LTV Formula

LTV = Loan Amount / Property Value

Property Value = Lesser of purchase price or appraised value

LTV Example

ScenarioValue Used
Purchase price: $300,000, Appraised value: $310,000$300,000 (lower)
Purchase price: $300,000, Appraised value: $290,000$290,000 (lower)

Example Calculation:

  • Purchase price: $400,000
  • Appraised value: $410,000
  • Loan amount: $380,000
  • LTV = $380,000 / $400,000 = 95%

Combined Loan-to-Value (CLTV)

CLTV includes all liens on the property.

CLTV = (1st Mortgage + 2nd Mortgage + Other Liens) / Property Value

CLTV Example:

  • Property value: $500,000
  • First mortgage: $400,000
  • HELOC: $50,000
  • CLTV = ($400,000 + $50,000) / $500,000 = 90%

High Combined LTV (HCLTV)

HCLTV includes the full credit limit of revolving credit lines, not just the drawn balance.

HCLTV = (1st Mortgage + Full HELOC Limit) / Property Value

LTV Significance

LTV RangeImplications
80% or lessNo PMI required on conventional
80.01-95%PMI required on conventional
Over 95%Higher PMI rates, fewer loan options
Over 100%Underwater (loan > value)

Automated Valuation Models (AVMs)

AVMs are computer programs that estimate property values using algorithms and data analytics.

How AVMs Work

ComponentDescription
Data SourcesPublic records, MLS data, previous sales
AlgorithmStatistical models, machine learning
OutputEstimated value with confidence score

AVM Advantages

  • Fast (seconds vs. days for appraisal)
  • Low cost ($10-50 vs. $400-800 for appraisal)
  • Objective (no human bias)
  • Consistent methodology

AVM Limitations

  • Cannot inspect property condition
  • May miss unreported improvements
  • Less accurate in rural areas
  • Limited comparable data in some markets
  • Cannot assess unique properties

When AVMs Are Used

Use CaseDescription
Appraisal WaiversSome refinances don't require full appraisal
HELOCsOften use AVM instead of appraisal
Portfolio MonitoringLenders track collateral values
Pre-qualificationInitial value estimates
Quality ControlCompare to appraisal results

Appraisal Waivers

Fannie Mae and Freddie Mac offer appraisal waivers for certain transactions.

Eligibility Factors

FactorRequirement
Property Type1-unit, primary residence typically
LTVUsually 80% or less
Transaction TypePurchase or limited cash-out refinance
AUS FindingMust receive waiver offer from DU/LPA
Property DataSufficient data for AVM confidence

When Waivers NOT Allowed

  • Cash-out refinances (generally)
  • FHA, VA, USDA loans (require appraisal)
  • Construction loans
  • Very high LTV transactions
  • Properties with insufficient data

Appraisal Issues and Resolution

Common Appraisal Issues

IssuePotential Impact
Low ValueMay require larger down payment
Condition IssuesRepairs may be required
Comparables Too OldMay need more current sales
Subject to RepairsCompletion required before closing

Recourse for Low Appraisal

  1. Request Reconsideration of Value (ROV) with additional comparables
  2. Order a second appraisal (at borrower's expense)
  3. Renegotiate purchase price
  4. Borrower brings additional funds
  5. Cancel transaction (if allowed by contract)

Key Takeaways

  • Full appraisals are required for most federally related transactions
  • Appraiser independence rules prohibit loan production staff from selecting or influencing appraisers
  • The sales comparison approach is most common for residential properties
  • LTV uses the lesser of purchase price or appraised value
  • CLTV includes all liens; HCLTV uses full credit line limits
  • AVMs provide quick, low-cost valuations but cannot assess condition
  • Appraisal waivers are available for certain low-risk transactions
