The buyer who knows first whether the figures hold bids first.

Institutional buyers want to place around CHF 19.8bn in 2026. The market offers about CHF 14bn (JLL, 2026).

An external valuation takes days and pays off for the two dossiers that deserve it. Cardo is the step before: you decide which two those are and file the other fourteen with reasons.

Seven checks for your IC.

Gross yieldRecomputed from in-place income.
Rent potentialWhat tenancy law allows, and by when.
Tax burdenThe municipality next to its neighbours.
Density reserveWhat the parcel still legally allows.
Fair entry priceThe range at which the asset meets your mandate criteria.

Cardo does the arithmetic

Cardo checks the exposé's claims against cantonal and municipal data, the commercial register and tenancy law.

Read the memo

Verdict, fair entry price, open risks and questions for the seller. As a link and as a PDF.

Every figure in the memo names its source.

Cardo works from cantonal and municipal data and shows in the memo where each figure comes from. The memo says what is established, what is an assumption and what is missing. The same dossier leads to the same finding.

What Cardo can't do today

Parcel-exact zoning exists only for the City of Zurich so far. Elsewhere Cardo works with zone bands.

Tax and rent data cover about 80 municipalities.

We check the counterparty only when it is a company.

Cardo replaces neither a formal valuation nor legal advice.

We take no money from sellers.

Praeclarum holds no broker mandates and earns no commissions. The memo goes to the party whose capital is at risk. That is why it can say no.

Riehenring 15, Basel, CHF 3.65m

private mandate, CHF 1 to 6m
4.0% at the top of the Basel band, in-place rent 46% below the median. A protection zone and building bans from 1929 and 1939 limit densification.

Building land, Weidstrasse 12, Kloten, CHF 1.85m

private mandate, CHF 1 to 6m
A utilisation ratio of 33% gives about 216 m² of gross floor area. The land price of about CHF 8'560 per m² of floor area nearly uses up the Kloten band before construction and demolition costs.
