Common questions
- Can Immowiser help me buy property in Germany as an investor or owner-occupier?
- Yes. Immowiser models both rental investment (Vermietung / Kapitalanlage) and owner-occupier (Eigennutzung) paths in one workflow; from assumptions and documents to a deterministic go/no-go verdict, confidence score, and action plan.
- Can expats use Immowiser to buy property in Germany?
- Yes. Immowiser is built for anyone buying in Germany, including expats: full English UI, German tax and cost logic (Grunderwerbsteuer, AfA, WEG, Hausgeld), and residency-aware financing hints. You stress-test an Exposé before committing; your mortgage broker, Makler, and Steuerberater stay in charge of approval, contracts, and tax advice.
- I already work with a mortgage broker or property advisor in Germany. Where does Immowiser fit?
- Immowiser is the diligence layer before and between advisor sessions: a proof-backed memo from your Exposé assumptions so conversations focus on strategy, not spreadsheet guesswork. Many buyers and professionals use it together; Immowiser does not replace regulated advice or financing placement.
- Is Immowiser available in English for international buyers?
- Yes. Switch between English and German across the marketing site and app. Educational pages (guide, glossary, compare) and core workflows support expats who need clarity on German deal economics without losing nuance on AfA, KfW signals, or WEG costs.
- How does buying German property compare to ETF, pension, REIT, or crowdfunding?
- Immowiser is not a securities broker; it helps you stress-test a specific property deal with cashflow, tax-oriented inputs (AfA, Grunderwerbsteuer), and holding-period logic so you can compare a concrete listing against passive alternatives on your own terms.
- Is Immowiser an alternative to Immocation, Hypofriend, or ImmobilienScout24?
- Listing portals help you find properties; financing brokers help with loans; education communities teach frameworks. Immowiser focuses on decision proof: deterministic numbers, document-aware assumptions, and an auditable verdict before you commit capital.
- Why use Immowiser instead of ChatGPT or ThinkImmo for a German property?
- Chat tools can invent KPIs and forget your Exposé. Immowiser runs a deterministic German engine first (AfA, GrESt, cashflow, KfW signals), saves versioned scenarios, requires confirmed assumptions, then optionally adds deal-specific AI explanation; never as the source of truth.
- Can real estate agents, mortgage brokers, or financial advisors use Immowiser?
- Yes. Real estate agents, mortgage brokers, and financial advisors use Immowiser to walk into client meetings with structured proof, scenario compare, and defensible memos. Your judgment and mandate stay central; Immowiser adds analytical depth that makes your advice land faster.
- Which property types does Immowiser support?
- Apartments (Eigentumswohnung / ETW), houses, new-build and existing stock, cash or financed purchases, and landlord vs owner-occupier tax orientation; with WEG, energy class, KfW, and municipal funding signals where relevant.
- Is Immowiser tax or legal advice?
- No. Immowiser is a calculation and decision-support tool. Outputs are estimates based on your inputs and documented rules; verify with a Steuerberater and legal advisor before acting.
