Buyer’s Q&A
How does Co-Ownership Property research its market data?
Three sources: operator-published inventory and resale data; regulatory filings where available (Companies House, CVR, equivalent registries); and our own marketplace data on enquiries, days-on-market and resale velocity. Cross-checked across sources before publication.
The short answer: COP's market research draws on three primary sources, cross-checked against each other. First, operator-published data — inventory counts, pricing, and resale stats published on operator websites and verified quarterly. Second, regulatory filings where operators file accounts (UK Companies House, Danish CVR, Spanish corporate registry) — independent verification of corporate facts. Third, our own marketplace data — directional patterns on buyer enquiries, days-on-market, resale activity, treated as directional only with anonymised aggregation. Where sources disagree, we flag the variance rather than picking a side.
Source 1 — Operator-published data
Every credible single-property fractional operator publishes core data on their website: current inventory, pricing per share, annual fee structures, sometimes resale-time statistics. We capture this quarterly and verify against the operator's stated property count. Operator-published data is the foundation of comparative pricing and inventory analysis across the category.
Limitations: operators tend to present data favourably to themselves; aggregated category-level claims (sometimes referenced as if independent) usually trace back to operator-supplied figures.
Source 2 — Regulatory filings
Where operators file accounts, those filings provide independent verification of corporate facts: founding year, registered address, officers, audited turnover (where filed), and corporate group structure. Active sources we use:
- UK Companies House — for UK-incorporated operators
- Danish CVR + Proff DK — for Danish-incorporated operators (e.g. 21-5)
- Spanish corporate registry — for SL-structured operators
- French INSEE / Infogreffe — for SCI-structured operators
- US Secretary of State filings (Delaware, Florida, California etc.) — for LLC-incorporated operators
Limitations: filing depth varies by jurisdiction; some operators file minimal accounts that don't give meaningful operational insight.
Source 3 — COP's own marketplace data
Our own marketplace produces directional data on buyer enquiries, destination demand patterns, days-on-market for listings, and resale activity. We treat this data as directional only — used for trend analysis and category-level pattern recognition, never for specific operator-vs-operator claims and never with individual-buyer identification.
The anonymisation discipline: published research uses directional terms ("demand for X has risen materially") rather than specific numbers, doesn't identify specific buyers or listings, and aggregates across enough data points that no individual transaction is traceable.
Cross-checking and variance handling
When sources disagree (e.g. an operator's claimed inventory count differs from their website's current listings; a trade-press article cites a number that contradicts the operator's regulatory filing), we cross-check before publishing. Where the variance can't be resolved confidently, we flag it rather than picking a side — readers can see the conflict and make their own judgment.
What we don't claim to know
Three categories of data we don't try to publish because the underlying sourcing isn't reliable enough. First, specific operator profitability — most operators don't file detailed accounts. Second, comparable operator-by-operator annual-fee data — too many definitional differences in what's included. Third, future market forecasts beyond directional trend extrapolation — fractional is too young a category to forecast with confidence.
Update frequency
Standard cadence: quarterly refresh of inventory and pricing data; annual refresh of corporate-filing data; ongoing capture of our own marketplace data; ad-hoc updates when material events warrant (operator changes, regulatory shifts).
What buyers should know about our research
Three things. First, our research is editorial work, not investment advice — useful for understanding the category, not a substitute for the buyer's own due diligence on a specific operator. Second, we cite sources where possible so readers can verify independently. Three, we update content when underlying data shifts — outdated claims get corrected rather than left in place.
The published research output
Our research is published in three formats. First, this Q&A library — short-answer reference material updated continuously. Second, comparison guides at /compare/ — operator-by-operator and category comparisons. Three, occasional longer-form research reports published at /research/.
