Where Our Data Comes From, and Who Does the Verifying
Data services are the starting point for our research, not the finished product. Every comparable sale in a Coastline Appraisal report is researched, verified and analyzed by the appraiser. The services listed below supply source data; the verification is ours.
Source Data We Start From
We use these data providers to identify potential comparable sales, rentals and market trends:
📊 Multiple Listing Services (MLS) – Real-time sales and market trends
🏦 Public Records & County Assessors – Ownership histories, recorded deeds and tax data
📉 CoStar, LoopNet & Crexi – Comprehensive commercial property insights
📈 Economic & Demographic Reports – Market forces shaping property values
Verification: The Appraiser’s Job, Not the Database’s
A listing service or database can tell us a sale happened. It cannot tell us whether the price was arm’s length, what the terms were, or what the buyer intended to do with the property. So we confirm each comparable sale ourselves, directly with:
✅ Buyers & Sellers – Understanding actual sale motivations and terms
✅ Real Estate Brokers & Agents – Validating market trends and off-market activity
✅ Developers & Investors – Insight into planned projects and future demand
Why It Matters
An appraisal is only as strong as the comparable sales behind it, and a sale is only as reliable as the verification behind it. By treating data services as source data and a starting point, and doing the research, verification and analysis ourselves, we deliver valuations that reflect what actually happened in each transaction.
When accuracy matters, work with an appraiser who verifies the sales personally rather than taking a database’s word for it.
