The five areas that will make your wealth grow

We have already created strategies for around 8000 clients so they become financially independent.

This is how we do it:

The undiscovered potential for your wealth accumulation: converting taxes into wealth.

1. Tax-deductible savings rate for investments

A high tax rate is not always a disadvantage, it also opens up many doors for tax savings.

An example: With the right strategy, it is possible to deduct the savings rate, for example for investment funds or ETFs, from taxes. With a high tax rate, this increases the tax refund significantly – the tax refund quickly increases by over €1000 per year. The reimbursement can of course also be reinvested, resulting in a gigantic yield advantage.

2. Increase net income by saving on social security

Taxes on gross income are relatively high in Germany. But there are also opportunities to save on social security contributions.

A change in social security can save employees an average of €200 per month. The monthly savings can be invested to create another major financial benefit.

3. Tailored investment strategy

Especially nowadays, an optimal investment strategy is a must-have. Due to the high inflation, investments should be made anyway. Otherwise, the savings lose their value. However, mistakes in investment decisions are also costly. A unique strategy must be chosen that takes short, medium and long-term investments into account. In addition, high-interest income and dividends are necessary to ensure your financial freedom.

4. Comprehensive real estate concept

In a professional investment concept, of course, rented properties also have a high priority. You need high rental income to stop being dependent on your labor.

But many investors lack the know-how to acquire real estate in a structured way. We support our customers in all individual areas. From the property search, to the analysis of the figures, the examination of the building fabric, to the management of the property.

5. Combination of investment opportunities

The Proper API is characterized by creating interfaces between the individual disciplines.

The savings rate of various investments is tax deductible. The tax refund is reinvested. Contributions are saved in social insurance, which in turn are also invested in a tax-optimized manner. This creates another tax benefit that can be invested.

Buying real estate can also create opportunities to save on taxes.

It becomes clear how great the financial advantage of our customers is through a tax-optimized investment strategy.

  • How can I imagine the consulting and the strategy development?

    We divide the consultation into several steps.

    - We start with social security and tax savings to increase net income and save money
    - We then create a general, tax-optimized investment strategy on a monthly and one-time basis
    - Individual investment opportunities are now identified and discussed in detail

    The process looks like this:

  • How much money do I need to invest?

    One of the biggest mistakes is that most people start too late. You don't necessarily need large individual sums to invest. We can also begin together and start with monthly savings rates.

    Hardly any equity is required for a property either. Let's check together how much equity you need for your wishes and goals.
