Important Disclaimer
Immowiser is a data-driven decision-support hub for German property decisions (rental / buy-to-let and simplified owner-occupier orientation). It is not tax, legal, financial or investment advice. All outputs (including verdict, action plan, and triggers) are estimates based on your inputs and the rules applied at calculation time. Owner-occupier mode uses simplifications — not individual tax advice. Laws and programmes (AfA, KfW, transfer tax, energy rules) change often. User-maintained municipal/funding entries (including payout timing and 'apply to model') are assumption inputs and may differ from actual approvals and program terms. Built-in plausibility/conflict checks are technical aids, not legal eligibility determinations. You are responsible for your decisions. Verify with a qualified Steuerberater and/or legal advisor before acting. No liability for financial loss, tax outcomes, or decisions made using this tool.
