2. MLS and market data platforms

Zillow — https://www.zillow.com/home-values/33435/meridian-id/
Realtor.com — market trends, rental estimates

Confidence level: VERIFIED (MLS) / ESTIMATED (aggregator-derived metrics)
Update cadence: Monthly (MLS reports) / Real-time (platform data)
Geographic scope: City of Meridian unless otherwise noted; some metrics reported at Ada County level

3. Broker intelligence and operator analysis

Renew Internal Analysis:

Deal flow observations from active Meridian acquisitions
Underwriting assumptions based on closed transactions
Neighborhood-level insights from boots-on-ground operations

Confidence level: OPERATOR
Update cadence: Continuous (deal-driven) / Quarterly (formal review)

4. Survey and third-party research

National and regional research:

CoStar — commercial real estate data
NARPM (National Association of Residential Property Managers) — rental market benchmarks

Confidence level: ESTIMATED (survey-based) / DATED (if publication lag exceeds 90 days)
Update cadence: Quarterly to annual depending on source

Confidence Levels Explained

Every metric on this site carries an implicit confidence tag:

Level	Definition	Example
VERIFIED	Sourced from official government record or direct MLS data	Meridian UDC §11-4-3-12 ADU standards; Ada County median sale price $555K (March 2026)
ESTIMATED	Derived from aggregator models or survey data	Zillow rent estimate $2,395/mo for 3BR; First Street flood risk projections
OPERATOR	Renew Group interpretation based on deal flow and market observation	"Renew take: Paramount neighborhood flips underperform due to HOA restrictions"
DATED	Sourced data older than 90 days; still relevant but not current	2023 Census ACS 1-Year population estimate (published 2024)

When a metric's confidence level is below VERIFIED, we note it inline: "estimated," "operator view," or "as of [date]."

Update Cadence by Data Type

Geographic Scope Definitions

City of Meridian:

Incorporated city limits as defined by Meridian city boundary
Excludes Meridian Area of Impact (unincorporated Ada County)
When data is Meridian-specific, we state "City of Meridian" or "Meridian city limits"

Ada County:

Includes Meridian, Boise, Eagle, Kuna, Star, Garden City, unincorporated areas
MLS data often reported at county level; we note "Ada County" when Meridian-specific data unavailable

Treasure Valley / Boise Metro:

Ada County + Canyon County (Nampa, Caldwell, Middleton)
Used for regional context only; never substituted for Meridian-specific data without disclosure

Neighborhood:

Submarket within Meridian (e.g., Paramount, Bridgetower, Downtown Meridian)
Boundaries defined by subdivision plat, HOA jurisdiction, or common usage
When boundaries are ambiguous, we note "approximate boundaries" and describe via major streets

Data Verification Process

Step 1: Source identification
Every metric begins with the highest-authority source available. If City of Meridian publishes it, we use that. If not, we move to Ada County, then regional, then third-party.

Step 2: Cross-reference
When possible, we verify metrics against a second source. Example: Median sale price from IMLS cross-checked against Redfin/Zillow aggregator data.

Step 3: Date and scope tagging
Every metric is tagged with publication date and geographic scope. "Ada County median $555K (March 2026)" is not the same as "Meridian median $560K (March 2026)."

Step 4: Confidence assignment
VERIFIED / ESTIMATED / OPERATOR / DATED tag applied based on source type and recency.

Step 5: Inline citation
Every metric cited inline with source name + date. Example: "Meridian median sale price hit $560K in March 2026, up 3.7% YoY (Redfin, accessed May 2026)."

Step 6: Stat card annotation
Key metrics also emit a [STAT_CARD] block for pull-stat rendering and future database ingestion.

Operator Interpretation Standards

"Renew take:" label required
Any interpretation, projection, or strategic recommendation is prefaced with "Renew take:" in body text and tagged [RENEW_TAKE] for system parsing.

Separation from fact
Operator views are never presented as verified data. Example:

Meridian median sale price hit $560K in March 2026, up 3.7% YoY (Redfin, May 2026).
Renew take: This price point creates a narrow flip margin for sub-$500K acquisitions unless ARV exceeds $620K post-rehab.

No speculation as fact
If we don't have data, we say so: `` — never fabricate.

Ordinance Citation Standards

Every zoning/ordinance reference must include:

Specific code section (e.g., Meridian UDC §11-4-3-12)
Effective date or last amendment date
Official source URL
Disclaimer: "Verify current standards at [official URL] before any development decision."

Example:

Meridian allows accessory dwelling units (ADUs) in all residential zones under UDC §11-4-3-12, last amended by Ordinance 25-2102 (effective November 18, 2025). Maximum size: 900 SF or 50% of primary dwelling GFA, whichever is less. Owner-occupancy required for either primary or ADU. Verify current standards at https://library.municode.com/id/meridian before any development decision.
