Inferred read-only

Potential side effects

compare_rent_vs_buy

Compare renting versus buying a Swiss home over a multi-year horizon: total costs, net worth in both paths, break-even year, tax effects (Eigenmietwert, deductions), and a verdict.

Inferred read-only

calculate_pension_buyin

Analyze a Swiss pension fund (Pensionskasse) buy-in: immediate income-tax saving, capital withdrawal tax at retirement, and a net comparison against investing the same amount privately, including the 3-year blocking period check.

Inferred read-only

get_mortgage_rates

Get current or historical Swiss mortgage interest rates (SARON and fixed terms) across major banks and insurers, from grundheim.ch's daily rate comparison.

Inferred read-only

get_municipality_profile

Get key facts for any of the 2122 Swiss municipalities: canton, district, population, postal code, and the cantonal/municipal income-tax multipliers.

Inferred read-only

get_market_price_context

Get current residential asking-price statistics (median CHF per m² and listing counts) from grundheim.ch's live market data — overall, and for a specific municipality when one is given.

Inferred read-only

generate_handover_link

Create a short, attributed link into grundheim.ch for the pages this tool can represent: a by-location tax calculator or Nebenkostenrechner, a municipality profile, the live mortgage-rate comparison, the mortgage calculator, or account registration.

Potential side effects

calculate_capital_withdrawal_tax

Inferred read-only

calculate_purchase_costs

Calculate the one-time incidental purchase costs (Nebenkosten) of buying Swiss property: land-registry fee (Grundbuch), notary costs, and transfer tax (Handänderungssteuer).

Potential side effects

calculate_imputed_rental_value

Inferred read-only

rank_municipalities_by_tax

Rank the municipalities within a Swiss canton by their tax multiplier (Steuerfuss / income tax rate), cheapest or most expensive first.

Inferred read-only

get_safety_statistics

Get official Swiss burglary (Einbruch) statistics per 1,000 residents from federal police crime data: the all-canton ranking, or one canton in focus with its national rank.

Inferred read-only

get_price_trend

Get the Swiss residential property price trend over time: the national BFS price index (annual, 2017 onward) and, for a Canton Zürich municipality, the local median sale-price time series for houses and apartments.

Inferred read-only

benchmark_ask_price

Judge whether a Swiss property's asking price is high or low for its location, by comparing it against other current asks in the same municipality (and, where official sold data exists — Zürich city and Geneva communes — against actual sale prices).

Inferred read-only
