Mortgage Calculator

How is it calculated?

The model requires at least 20% equity capital. It assumes 5% imputed mortgage interest, 1% annually for maintenance and additional costs and the repayment of the mortgage portion of two thirds of the purchase price within 15 years. The upper limit is one third of gross income.

Additional purchase costs must be financed separately. Your bank will check, among other things, the origin of your own funds, age and other obligations. The result is an orientation. Your entries remain in your browser.

WHY WE CAN OFFER THESE CONDITIONS

We save on structures.
Not at the service.

We consciously avoid expensive representative offices, franchise fees, unnecessary fixed costs and services without real benefit. Our focus is on the essentials: marketing real estate professionally, providing personal support and concluding transactions quickly, easily, discreetly and carefully. We pass on the costs saved to our customers.

01 / INDEPENDENT

No expensive detours

No franchise fees, no expensive representative offices and no unnecessary administrative apparatus. We invest our resources where they actually advance sales.

02 / SLIM & FAST

Simple. Fast. Discreet.

On average, we support around 100 to 120 real estate transactions every year - from purchases and sales to direct purchases to investor and portfolio transactions. Well-rehearsed processes enable short decision-making processes, flexible deadlines and quick, careful processing.

03 / RANGE

Marketing instead of office pomp

Professional documentation, the relevant major real estate portals, targeted viewings and our buyer and investor network are the focus.

04 / PERSONAL & CONNECTED

The right team for every transaction

Typically available seven days a week. With well-rehearsed investor, financing, architectural and notary partners, we accompany buyers and sellers right through to the handover.

Our principle: We save on unnecessary costs, not on marketing or care. We strive for the best possible sales price for owners and support buyers transparently and personally. External specialist services and official fees must be paid separately – unless otherwise agreed.

CLEAR AND TRANSPARENT

Selling your house?
See how much you could take home.

With just a few details you can see your possible payout proceeds after the mortgage, our commission and typical seller costs. You can add additional taxes and bank costs. We explain the sale in five simple steps.

OUR ATTITUDE

Three principles for our work.

“An estimate must be understandable.”

We will explain to you how location, condition and documents influence the price estimate. So you can decide the next step yourself.

«The first impression counts. The last one remains."

A professional appearance is important - from the presentation of your property to the final conversation, the notarisation and the handover of the keys.

“After business is before business.”

A successful placement does not end the customer relationship for us. We remain available and rely on trust, reliability and long-term recommendations.
