Frequently asked questions

Behavioural finance examines how psychological factors and behavioural patterns influence financial decisions. It focuses on emotional reactions and cognitive biases that can lead to irrational investor behaviour.

The behavioural gap describes the difference between the return of an investment and the return an investor actually achieves. It is usually caused by poor decisions about when to buy and sell, or by a lack of discipline.

Emotions such as fear and greed, as well as thinking errors such as overconfidence or herding, mean that decisions are not made on a purely rational basis. These patterns are deeply rooted in human behaviour.

A clear investment strategy, a long-term focus and professional guidance help to reduce emotional misjudgements. Discipline and structure are crucial for investment success.

Yes, if projects are carefully vetted. Without battery storage and legal safeguards, however, the risks have risen considerably. Negative electricity prices and delays in grid connection in particular make a well-founded strategy essential.

Good rooftop projects achieve a gross yield of up to 9 per cent. What matters, however, is that calculations are not based on politically uncertain subsidy packages and that storage solutions are factored in.

As there is no consumer protection comparable to that in the real estate sector, many contracts are unfavourable to investors. The risks lie above all in unclear rules on rescission, missing collateral and payments that fall due too early.

Without storage, remuneration can be lost entirely when electricity prices are negative. Storage not only secures income but also opens up additional revenue streams through self-consumption and grid services.

Ideally, you should have at least 8 to 20 per cent of the purchase price, including ancillary costs, available. Those who put in less must expect less favourable interest rates and higher monthly payments.

Yes – if the financing and the quality of the property are right, a purchase can make economic sense even at 4 per cent interest. What matters is not the interest rate but the overall return after taxes and value development.

At the latest before signing the purchase contract, the financing, energy efficiency and legal structure should have been checked. Correcting things afterwards usually costs many times more.

Important factors are population trends, the structure of local employers, infrastructure and rent dynamics over recent years. A low entry price without prospects is not an advantage but a risk.
