Standard online calculators fail in Switzerland because they ignore our unique tax system. "Buy vs Rent CH" is a native iOS app built exclusively for the Swiss market. It accurately calculates the Eigenmietwert (imputed rental value), the true opportunity cost of ETF investments versus a 20% down payment, and mandatory 2nd mortgage amortization rules. Stop guessing with generic spreadsheets and start making data-driven real estate decisions based on actual Swiss financial law.
