### Tool changes

- 2026-10-18 `get_rules` changed (description)
  - before: List the statutory values the engine uses on a date (tax and fee rates, broker caps, minimum repair reserve, MRG cut-off dates), each with legal basis, source URL and the date it was last verified, plus the default assumptions and risk thresholds. Use to cite sources or to explain how a number was calculated.
  - after: List the statutory values the engine uses on a date (tax and fee rates, broker caps, minimum repair reserve, MRG cut-off dates, Richtwerte per state, AfA rates, land shares, income tax brackets), each with legal basis, source URL and the date it was last verified, plus the default assumptions and risk thresholds. Use to cite sources or to explain how a number was calculated.
- 2026-10-18 `underwrite_property` changed (description, inputSchema)
  - before: Analyse an Austrian residential property as a rental investment: acquisition costs, annuity loan payment, monthly cash flow before tax, gross and net yield, cash-on-cash return, debt cover (DSCR), break-even rent, whether statutory rent caps (MRG) apply, and risk flags. Use when evaluating whether a specific flat or house is a good buy-to-let deal. Inputs in EUR; rents and owner costs are monthly and net of VAT. Pass what you know: missing facts fall back to documented assumptions and are flagged. Not covered: income tax on rent, rent increases or interest-rate changes over time, the exact Richtwert cap.
  - after: Analyse an Austrian residential property as a rental investment: acquisition costs, annuity loan payment, monthly cash flow before and after income tax, gross and net yield, cash-on-cash return, debt cover (DSCR), break-even rent, whether statutory rent caps (MRG) apply and the Richtwert cap, depreciation (AfA) with the legal land share, a 25-year Liebhaberei check, and risk flags. Use when evaluating whether a specific flat or house is a good buy-to-let deal. Inputs in EUR; rents and owner costs are monthly and net of VAT. Pass what you know: missing facts fall back to documented assumptions and are flagged. The JSON is compact by default (key figures, flags, citations); pass detail "full" for every line, the tax years and the rules used. Not covered: rent increases or interest-rate changes over time, tax credits, Richtwert surcharges and deductions (Zuschläge/Abschläge).
- 2026-10-18 `estimate_acquisition_costs` changed (description, inputSchema)
  - before: Calculate the one-off costs of buying residential property in Austria on top of the price (Kaufnebenkosten): real estate transfer tax (Grunderwerbsteuer), land-register court fees, broker commission with a check against the legal maximum, and lawyer/notary contract costs, each with VAT where it applies. Use when someone asks what buying a specific flat or house in Austria costs in total. Every statutory line cites its legal basis and source. Amounts in EUR. Not covered: bank or valuation fees, purchases within the family, exemptions for a primary residence.
  - after: Calculate the one-off costs of buying residential property in Austria on top of the price (Kaufnebenkosten): real estate transfer tax (Grunderwerbsteuer), land-register court fees, broker commission with a check against the legal maximum, and lawyer/notary contract costs, each with VAT where it applies. Use when someone asks what buying a specific flat or house in Austria costs in total. The JSON lists the cited legal bases and sources once; pass detail "full" for every line item with its calculation and its own citations. Amounts in EUR. Not covered: bank or valuation fees, purchases within the family, exemptions for a primary residence.
