Ten instruments
The Instruments
Acquisition cost, holding cost, yield, financing, exit, a budget across the map, currency, own or rent, readiness and portfolio balance. All ten run in the browser and none of them sends a number anywhere.

Every instrument runs in your browser. Nothing you type is sent anywhere, and nothing on this page contacts another server. All figures are the desk's estimates at September 2026 and are orientation rather than tax, legal or valuation advice.
The Private Letter
One letter a month.
One letter a month: what moved in the hotspots, one anonymised sale explained, one number worth knowing. No advertising, no tracking, one click to leave.
