BRAVE vs MISMO 3.5: How They Differ

TL;DR

Dimension	BRAVE	MISMO 3.5
Scope	CRE appraisal data only	Residential mortgage origination, broadly
Property type	Commercial (office, retail, industrial, multifamily, hospitality, special purpose)	Primarily residential 1-4 unit + condos
Created by	Valcre	MISMO (industry consortium)
File format	XLSX or CSV	XML
Field count	99 structured fields	Thousands across modules
Where the spec lives	usebrave.org	mismo.org
Validation	Free public validator at usebrave.org	Schema validation via XSD
First widely-deployed mandate	Bank OZK, March 15, 2026	Fannie/Freddie UCD ~2017

These are different standards for different markets. They do not compete with each other.

What Each Standard Is

BRAVE

BRAVE is the Banking Real Estate Appraisal Valuation Exchange. It is a 99-field schema covering commercial real estate appraisal output:

• 3 Job fields (engagement metadata)
• 52 Property fields (location, building, site characteristics)
• 16 Income fields (PGI through NOI)
• 24 Value fields (cap rate, value conclusions per approach)
• 4 Appraiser fields (identity, credential)

BRAVE was created by Valcre, a CRE appraisal platform, and published as an open standard in 2025. Bank OZK requires BRAVE-format delivery alongside the PDF report effective March 15, 2026.

MISMO 3.5

MISMO is the Mortgage Industry Standards Maintenance Organization, a subsidiary of the Mortgage Bankers Association. MISMO maintains a family of XML schemas covering the residential mortgage origination, servicing, and securitization lifecycle. MISMO 3.x — the v3 generation — has been the production standard for residential mortgage data exchange since the 2010s.

MISMO 3.5 covers things like:

• Loan application (URLA / Form 1003 equivalent)
• Appraisal data via the UAD (Uniform Appraisal Dataset) for residential
• Closing disclosure (UCD)
• Initial / final loan estimate
• Servicing data exchange

The residential appraisal portion of MISMO 3.5 is the UAD — which is itself a separate, narrower spec administered by Fannie Mae and Freddie Mac.

Where People Confuse Them

Both BRAVE and MISMO are "real estate data standards." That's where the similarity ends. The confusion usually comes from:

1. People generalizing "MISMO" to mean "any structured appraisal data." MISMO covers residential origination broadly; its appraisal slice is UAD. There is no MISMO module for commercial appraisal data.
2. People asking "why doesn't BRAVE just use MISMO?" Because MISMO doesn't cover the commercial appraisal use case. Building it would require the residential mortgage industry consortium to take on commercial appraisal — which isn't their charter.
3. Crossover terminology. Both involve cap rate, NOI, GBA, and other CRE terms (residential UAD includes some income-approach fields for income-producing residential). The terminology overlaps because real estate vocabulary is shared.

Side-by-Side: What's Inside Each

BRAVE — example field set

Property.Type = "Multifamily"
Property.GrossBuildingArea = 178500
Income.PotentialGrossIncome = 4250000
Income.VacancyLoss = 212500
Income.EffectiveGrossIncome = 4037500
Income.NetOperatingIncome = 2422500
Value.CapRate = 0.06
Value.ReconciledFinal = 40375000

MISMO 3.5 — fragment

<APPRAISAL>
  <PROPERTY>
    <ADDRESS><AddressLineText>123 Main St</AddressLineText></ADDRESS>
    <PROPERTY_DETAIL>
      <PropertyCategoryType>SingleFamily</PropertyCategoryType>
    </PROPERTY_DETAIL>
  </PROPERTY>
  <APPRAISAL_VALUATIONS>...</APPRAISAL_VALUATIONS>
</APPRAISAL>

XML. Validates against an XSD schema published by MISMO.

The encoding model is fundamentally different — flat tabular for BRAVE, deeply nested XML for MISMO. That reflects each standard's history: BRAVE was designed for direct ingestion into bank LOS systems and Excel-based underwriting; MISMO was designed for system-to-system messaging across the full origination workflow.

Which Do You Need?

Map your work to one or the other:

If you are appraising…	You need…
Office, retail, industrial, multifamily, hospitality, special-purpose CRE	BRAVE (if your lender requires it)
Single-family residential, condo, 2-4 unit	UAD (via MISMO 3.5 for the full loan file)
5+ unit multifamily	Commercial — BRAVE territory
Mixed-use small property	Usually commercial — BRAVE

UAD residential appraisal delivery to Fannie/Freddie has been mandatory for years. BRAVE adoption is bank-by-bank — only Bank OZK currently requires it.

Can They Coexist?

Yes. A bank that originates both residential and commercial loans will receive UAD/MISMO-formatted residential appraisals (per Fannie/Freddie requirements) and BRAVE-formatted commercial appraisals (if it adopts BRAVE, which most haven't yet). The two pipelines run independently. There is no plan from either MISMO or Valcre to merge or align the standards.
