Kurzantwort: Wie viel Eigenkapital brauche ich wirklich?
- 20% Eigenkapital ist ein gängiger Richtwert; 30% bringen oft bessere Konditionen.
- Nebenkosten (ca. 8–10%) immer zusätzlich zum Eigenkapital einkalkulieren.
- Mehr Eigenkapital senkt Rate und Zinskosten, reduziert aber den Liquiditätspuffer.
- Einen finanziellen Sicherheitspuffer für Unerwartetes immer einplanen.

TL;DR
- •20% equity is a common benchmark; 30% often improves terms.
- •Closing costs should be added on top of equity.
- •Higher equity lowers payment but reduces liquidity.
- •Keep a safety buffer.
What do banks expect?
Under Austria's KIM-V regulation (introduced by the FMA in July 2022), banks are required to apply minimum equity thresholds for residential mortgages. While the regulation sets a formal floor of 10%, most Austrian lenders in practice require 20% of the purchase price — equivalent to an 80% loan-to-value (LTV) ratio — as their standard approval baseline. Borrowers with less equity can still qualify under exception quotas, but typically pay an interest rate premium of 0.2–0.5 percentage points and face stricter creditworthiness requirements.
At 30% equity (70% LTV), banks generally offer their best rates and most flexible terms. Critically, Austrian banks require closing costs (Nebenkosten — approximately 8–10% of the purchase price, covering transfer tax, land registry and notary fees) to be funded entirely from personal savings, not from the mortgage. Always plan equity plus closing costs together. (Sources: FMA.gv.at; OeNB Financial Stability Report 2024)
How does equity change your payment?
Higher equity reduces the loan amount and monthly payment.
Which equity sources count?
- •Savings or investments
- •Family gifts
- •Subsidies or savings plans
- •Own labor for renovation
Example calculation (350,000 €)
20% equity: €70,000 plus ~9% closing costs ≈ €101,500.
30% equity: €105,000 plus closing costs ≈ €136,500.
Higher equity lowers payments but ties up more cash.
Common mistakes to avoid
- •Ignoring closing costs in the equity plan.
- •Using all savings without a buffer.
- •Missing documentation for equity sources.
- •Planning a rate without reserves.
Checklist before the bank meeting
- •Proof of equity (statements, portfolios, gifts).
- •Closing cost budget and liquidity buffer.
- •Target payment and preferred term.
- •Income proofs and existing obligations.
How big should your buffer be?
Reserve cash for moving, furnishing, and rate increases.
