Exterior-Only (Drive-By) Appraisals: Scope, Limitations, and Documentation Requirements

Exterior-Only (Drive-By) Appraisals: Scope, Limitations, and Documentation Requirements

Exterior-Only Appraisals, also referred to as Drive-By Appraisals, have become an essential part of the modern residential real estate landscape. These limited-scope appraisals are widely used by lenders for faster processing in low-risk loan scenarios. While they provide a more efficient way to assess property value, they still require professional standards and reliable documentation to ensure accuracy.

When Are Exterior-Only Appraisals Used?

Drive-by appraisals are ideal for transactions involving:

• Home Equity Lines of Credit (HELOCs)

• Low loan-to-value (LTV) refinance applications

• Properties with high equity and minimal borrower risk

• Internal bank or portfolio reviews

  
  

When the lending risk is low, and a full interior inspection is unnecessary, exterior-only appraisals offer a practical alternative.

Required Documentation for a Compliant Drive-By Appraisal

Even though no interior inspection is performed, a drive-by appraisal must still meet compliance requirements. Appraisers must include:

• Street-view photos of the subject property

• A location map showing the property within its neighborhood

• A basic property sketch of the structure

• A completed Fannie Mae 2055 form

  
  

Appraiser X Suite helps appraisers compile and manage these documents quickly and securely, improving efficiency while maintaining compliance.

Key Limitations and Scope

Exterior-only appraisals rely on external visual inspections and third-party data. Appraisers typically use:

• Public records

• MLS listings

• Previous appraisal data

• Information from agents or homeowners

  
  

Because no interior assessment occurs, appraisers must make educated assumptions regarding interior condition. These assumptions must be clearly disclosed and supported with market data.

Best Practices for Reliable Exterior-Only Appraisals

To ensure credibility, appraisers should follow these industry best practices:

1. Use Verified Public Data: Leverage tax assessor information, MLS records, and reliable online sources.

2. Clearly State Assumptions: Include language that reflects the basis of your assumptions. For example: "The subject property is assumed to be in average condition based on exterior appearance and neighborhood trends."

3. Disclose the Appraisal’s Scope: Avoid misleading the reader by stating that no interior inspection was performed and assumptions were made.

4. Use Quality Comparable Sales: Choose comps with verified interior data, and apply proper adjustments when needed.
