Portfolio financing 30 years - Real estate loan Austria. The Lechner family from Linz faces a challenge: the family home they inherited is to be extensively renovated and become the center of their lives for the next few decades. But how can a young couple with two children finance a large existing property without overextending themselves financially? The answer lies in cleverly planned portfolio financing with a 30-year term.
Why existing financing with a 30-year term is becoming increasingly popular
In times of high real estate prices and rising interest rates, many households are turning to financing with a maximum term. A 30-year property loan enables low monthly installments - a decisive advantage for families with a limited budget. For the Lechner family, the monthly burden is reduced by over % compared to a 20-year loan model.
The cornerstones of existing financing: fixed interest rate, repayment & residual debt
Austrian banks are increasingly offering loans with a term of 30 to 35 years. It is important to have a long-term fixed interest rate: this keeps the rate calculable. The Lechner family opted for a 30-year fixed interest rate - currently often cheaper than shorter fixed rates. If you also plan with special repayments, you can massively reduce interest costs.
A key risk: despite long-term financing, a high residual debt can remain - especially with low repayments or bullet repayment models. A clear repayment strategy is therefore essential.
Checklist: Planning the 30-year financing
| Point | Recommendation |
|---|---|
| Runtime | 30 years for a low monthly installment |
| Fixed interest rate | as long as possible (20-30 years) |
| Repayment | Initially low, later increasing or plan for special repayments |
| Security | Mortgage + possibly life insurance or repayment vehicle |
Residual value and bullet financing: Opportunities and risks
Models with a final installment (balloon financing) or bullet loans can also be used for existing financing. These significantly reduce the monthly installment even further. The Lechner family deliberately decided against this model - the risk of a large residual debt in 30 years seemed too high.
Bullet repayment models are often combined with life insurance, building society savings contracts or securities deposits. Such financing models are usually only offered by banks if you have a very good credit rating and sufficient collateral - such as equity or repayment vehicles (e.g. life insurance or building society savings contract for later repayment).
Repayment-free start phases: Flexibility at the start of renovation
Many banks allow 1-3 redemption-free years - ideal for renovations. During this time, you only pay the interest, which eases the double burden (rent + loan). The Lechner family used the redemption-free phase to renovate in peace and only then start repayments.
Such models are particularly useful in the construction phase or for transitional financing, but they entail an increased interest cost risk.

How banks think: Why strict rules apply to residential real estate loans
Residential real estate loans are among the biggest financial decisions in life. At the same time, they represent a significant proportion of the total loan volume in Austria. Banks in Austria apply clear guidelines to ensure that neither borrowers are overburdened nor real estate bubbles are encouraged.
These are based on the recommendations of the Financial Market Authority (FMA) and include among others:
- A maximum Loan-to-value ratio of 90 % (
- One Annual credit charge of max. 40 % of the net income
- One Maximum term of 35 years
- An exemption limit for small loans under €50,000 (single person) or €100,000 (couples)
Further information can be found directly on the FMA website: FMA - Residential real estate loans in Austria
Banks may deviate from this in individual cases, but only do so for good reason - for example, in the case of very good creditworthiness or additional collateral.
