How Much Equity Do You Really Need to Buy a Property in Austria?

Buying an apartment in Austria often starts with a simple question: Can I afford the purchase price?

But if you are planning to buy a property in Vienna, the more useful question is: How much of my own money do I need before I can actually complete the purchase?

Your required savings depend on more than the property's price. You need to account for your down payment, acquisition costs, mortgage registration fees and the financing conditions offered by your bank. Your income, existing financial commitments and the property's accepted lending value can also influence the decision.

This is where the concept of Eigenkapital becomes important.

In Austrian property financing, Eigenkapital means the funds you contribute yourself rather than borrow from a lender. Understanding how much you need—and keeping it separate from the money required for taxes and transaction fees—is an essential step before making an offer.

In this guide, we explain how property financing works in Austria, how to estimate your upfront cash requirement and how to assess whether a property is financially realistic for you.

1. What Is Eigenkapital in Austrian Property Financing?

Eigenkapital is the money you contribute from your own resources when purchasing a property.

It can include savings and other funds that are genuinely available for the transaction. The amount required depends on how much of the purchase the bank is willing to finance and how you cover the additional acquisition costs.

For example, a buyer might have enough savings to cover the difference between the purchase price and a proposed mortgage but not enough to cover the taxes, registration fees and legal costs.

That buyer may still face a funding shortfall.

It helps to distinguish between three amounts:

1. Purchase price: The agreed price of the property.
2. Financing gap: The part of the purchase price not covered by the mortgage.
3. Total upfront cash requirement: The financing gap plus acquisition costs and any other payments that must be made from the buyer's own funds.

The third figure is the one you should calculate before committing to a purchase.

2. How Much Will an Austrian Bank Finance?

A bank does not assess a mortgage application solely on the basis of the property's advertised price. It also evaluates the property as collateral and considers whether the borrower can sustainably repay the loan.

Austria's current supervisory framework is important here.

The KIM-Verordnung, which previously established binding lending requirements, expired on 30 June 2025. Source: RIS, KIM-V §11

Following its expiry, the Financial Market Stability Board continued to recommend sustainable lending standards. The Oesterreichische Nationalbank summarised these guidelines in April 2026:

• Loan-to-value (LTV): no more than 90%.
• Debt-service-to-income (DSTI): no more than 40% of net income.
• Loan term: no more than 35 years.

Official source: Oesterreichische Nationalbank, 10 April 2026

These figures are important reference points, but they should be interpreted correctly. They are supervisory guidelines for sustainable lending, not a promise that every applicant can borrow 90% of a property's value. Individual banks assess applications according to their applicable policies, the borrower's circumstances and the collateral.

What does a 90% loan-to-value ratio mean?

Loan-to-value compares the loan amount with the value of the property accepted by the lender as collateral.

For illustration, if a lender accepts a property value of €400,000 and a loan represents 90% of that value, the calculation is:

€400,000 × 90% = €360,000.

The difference is €40,000.

This is an illustration of the LTV calculation—not a prediction of what a particular bank will lend. The bank's valuation may differ from the agreed purchase price, and the buyer still needs to account for acquisition costs.

3. What Are the Additional Costs of Buying Property in Austria?

Before calculating how much Eigenkapital you need, you should estimate the Kaufnebenkosten—the costs associated with completing the purchase.

The Austrian government's official guidance identifies the following principal expenses:

Acquisition cost	Standard rate or basis	Official source
Grunderwerbsteuer	Generally 3.5% of the purchase price	Austrian Federal Government
Grundbuch ownership registration	Generally 1.1% of the purchase price	Austrian Federal Government
Mortgage lien registration	Generally 1.2% of the registered lien's value	Austrian Federal Government
Real estate agent commission	Negotiable, subject to statutory maximums	Austrian Federal Government
Lawyer or notary	Depends on the agreed fee and services	Austrian Federal Government
Signature certification and administrative charges	Depends on the applicable fee rules and transaction	Austrian Federal Government

The 3.5% transfer tax and 1.1% ownership registration fee are standard starting points for an ordinary purchase. Special transactions and applicable exemptions can change the calculation, so the actual transaction should always be checked.

The mortgage registration fee is calculated on the registered lien, not automatically on the full purchase price.

Agent commission and professional fees should be based on the actual agreement and services required.

4. Example: How Much Cash Do You Need for a €400,000 Apartment?

Let's put these elements together using a hypothetical purchase in Austria.

Assumptions for this illustration:

• Purchase price: €400,000.
• Illustrative mortgage: €320,000.
• Standard transfer tax and ownership registration rates.
• An estate agent is involved, with the maximum gross commission used for illustration.
• Mortgage registration is based on a registered lien of €320,000.
• Legal and contract costs are estimated separately.

These assumptions are for planning purposes only. The mortgage amount is not a bank offer, and the professional fees depend on the actual transaction.

Estimated acquisition costs

Item	Calculation	Amount
Purchase price	—	€400,000
Real estate transfer tax	3.5% × €400,000	€14,000
Ownership registration	1.1% × €400,000	€4,400
Mortgage lien registration	1.2% × €320,000	€3,840
Agent commission, illustrative maximum	3.6% × €400,000	€14,400
Subtotal before legal and other costs		€436,640

The tax and registration rates come from the Austrian government's official property-purchase guidance. The illustrative agent commission reflects the statutory maximum of 3% plus VAT at the currently applicable 20% rate for a transaction above the relevant threshold. Official source: Austrian Federal Government

Legal fees, signature certification, bank charges and any other applicable costs must be added according to the actual transaction.

How much of your own money would this require?

Under the illustration, the purchase price is €400,000 and the proposed mortgage is €320,000.

The purchase-price funding gap is: €400,000 − €320,000 = €80,000.

The estimated acquisition costs listed above total €36,640, before legal and other costs.

Therefore, the buyer would need: €80,000 + €36,640 = €116,640, before legal and other costs.

This is the key distinction: a proposed mortgage that covers most of the purchase price does not eliminate the need to fund acquisition costs.

Your actual required cash contribution may be higher or lower depending on the bank's offer, the fees agreed, the property's valuation and the transaction's eligibility for any applicable exemptions.

5. Why 20% Equity Is Not a Universal Legal Requirement

You may encounter the rule of thumb that buyers should have at least 20% of the purchase price available as their own funds.

It is important to distinguish a planning assumption from a binding legal requirement.

The KIM-Verordnung expired on 30 June 2025. The current supervisory guidance summarised by the OeNB uses a maximum LTV guideline of 90%, alongside repayment-capacity and loan-term guidelines. It does not mean every buyer must provide exactly 20% equity, nor does it mean every buyer with 10% equity will qualify for a mortgage.

A bank may require a larger contribution based on its valuation, the applicant's income and expenses, the property and the overall risk of the loan.

For your own planning, it is therefore more useful to calculate several scenarios rather than assume one universal equity percentage.

6. Does Your Income Affect How Much You Need?

Yes. The amount of savings you have is only one part of the financing assessment.

A lender also needs to assess whether you can afford the repayments while meeting your other financial obligations.

The FMSG's current supervisory guideline, as summarised by the OeNB, sets a debt-service ratio reference point of no more than 40% of net income. This is a lending guideline rather than an assurance of approval. Official source: OeNB

The calculation considers the relationship between debt repayments and net income. Existing loans and other financial commitments can affect the lender's assessment of repayment capacity.

For that reason, two buyers with the same savings may receive different financing decisions.

Before choosing a property, estimate the monthly payment and consider how it fits into your budget. Also account for ownership expenses that sit outside the mortgage repayment, such as operating costs, maintenance and future repairs.

7. How to Calculate Your Own Eigenkapital Requirement

A practical calculation starts with the total cost of acquiring the property, not just the advertised price.

Use this sequence:

• Step 1: Establish the purchase price. Use the agreed price as your starting point, while recognising that the lender may use a different valuation for collateral purposes.
• Step 2: Estimate acquisition costs. Calculate transfer tax, ownership registration, mortgage registration where applicable, agent commission and professional fees. Use official rates where available and actual quotes for variable costs.
• Step 3: Establish the proposed mortgage. Use a realistic financing scenario, not the maximum amount you hope a bank might offer.
• Step 4: Calculate the purchase-price funding gap. Subtract the proposed mortgage from the purchase price.
• Step 5: Add acquisition costs. This gives you a preliminary estimate of the cash needed to complete the transaction.
• Step 6: Keep a reserve. Avoid assuming that every euro of your savings should go toward the purchase. You may need funds for moving, repairs, unexpected expenses or changes in your financial situation.

The result is a more realistic estimate of the money you need before making a commitment.

8. What Should You Prepare Before Speaking to a Bank?

Before requesting a mortgage offer, organise a clear picture of your financial position.

Prepare information about:

• Your available savings and other funds.
• Your regular net income.
• Existing loans and monthly financial commitments.
• The purchase price and details of the property.
• Your estimated acquisition costs.
• Your preferred loan amount and repayment structure.
• The cash reserve you want to retain after the purchase.

The bank will determine which documents it requires and how it assesses your application. These preparations help you understand your own limits before you begin negotiations.

9. Common Mistakes When Estimating Equity

• Mistake 1: Calculating equity as only the difference between the purchase price and mortgage. This overlooks acquisition costs that may need to be paid separately.
• Mistake 2: Assuming a 90% LTV guideline guarantees a 90% mortgage. The guideline is not a commitment by a bank to lend that amount. The lender's valuation and credit assessment remain important.
• Mistake 3: Treating the expired KIM-Verordnung as current law. The regulation expired on 30 June 2025. Current supervisory guidance should be described accurately and separately from binding legal requirements.
• Mistake 4: Using estimated fees as if they were fixed. Agent commission, legal costs and bank charges may vary. Obtain transaction-specific figures where possible.
• Mistake 5: Spending all available savings on the purchase. A property purchase creates ongoing responsibilities. Keeping a reasonable reserve can help you manage unexpected expenses after completion.

The Bottom Line

Buying property in Austria is not only about having enough money for the down payment. You also need to fund the costs of completing the purchase and satisfy the lender that the mortgage is affordable.

The most reliable approach is to calculate your purchase-price funding gap, add the acquisition costs supported by official rates and transaction-specific quotes, and then assess the monthly repayments against your financial situation.

For Immovesto, the goal is simple: help buyers understand the full financial commitment before they make a decision.

Calculate your required Eigenkapital before you commit to a property.
