I ran into an issue: |
- Change title to "How the Scottish mansion tax would affect constituencies" - Remove opinionated language and adjectives - Use British spelling (modelled) - Increase iframe height for better map display - Simplify key findings section Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Title: "Estimating the constituency distribution of the Scottish mansion tax" - Author: vahid-ahmadi Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Remove Glasgow share row from key findings table - Add Rettie Research link for ~457 sales estimate - Add Registers of Scotland link for price comparison Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Use official RoS figure (391 sales) instead of Rettie (425) - Update Edinburgh share to 47% (population-based) - Update top 10 table with population-weighted results - Edinburgh Northern & Leith now #1 (by population, not affluence) - Describe NRS population-based weighting methodology - Bump iframe cache version to v=8 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Link to gov.scot source for £16m estimate - Note that Band I/J rates not yet announced - Add Revenue Allocation section explaining proportional distribution - Clarify difference from UK repo where rates are known Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The Scottish Government's £16m figure has no published methodology. Now using UK Autumn Budget 2025 rates as benchmark: - Band I: £1,500/year (extrapolated) - Band J: £2,500/year (UK minimum) Implied revenue from annual sales: ~£657k Added stock figure (~11,000 properties from Savills) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Council tax applies to all properties, not just sales. Following uk-mansion-tax methodology: - Stock: ~11,000 (Savills) - Stock/sales ratio: ~26x - Stock-based revenue: £18.5m Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Explain why sales data needed (stock has no geographic breakdown) - Add comparison: our £18.5m vs govt verbal £16m - Link to LBC source for Finance Secretary quote Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
