Deal No. 6 · Wiesbaden · Couple, around €120k
Ten years on a 77 m² apartment in Wiesbaden, nothing down.
A 77 m² new build in Wiesbaden, bought with no money down: the loan of 578.341 € covers the price and the purchase costs. It qualifies for §7b Sonder-AfA, which runs for four years and then stops. Every year of the projection is below, from the part year in 2026 to the sale in 2036.

The deal
What was bought, and on what terms
Wiesbaden, 77 m², built 2026. Bought for 535.500 €, financed 108 % at 4,5 % fixed 10 y, against a 120.000 € income.

The loan covers the purchase price and the purchase costs, so nothing was paid at closing: 6 % transfer tax, 1,5 % notary and land registry, 0,5 % financing costs are all financed. Hessen, joint filing.
- Worst month before tax benefits
- −692 €
- In 2027, narrowing every year as rent rises
- After tax benefits, first full year
- +681 € / month
- The apartment carries itself from year one
- Total wealth if sold in 2036
- 232.285 €
- No own capital in: the loan covered the price and the purchase costs
Projection from the assumptions above. Rent is indexed 2 % a year, the household income grows 2 % a year, and the apartment is sold after the 10-year holding period, so the gain is tax-free. The §7b Sonder-AfA runs for the first four years only, which is why the tax benefit drops from about 15.000 € a year to about 6.000 € in 2030, and the month after tax benefits turns slightly negative with it.
The ten years, year by year
Cashflow before tax benefits

Cashflow after tax benefits

2026 is a part year. The purchase closed in May 2026, so those 8 months of ownership carry a full calendar year of tax effect, and the first bar sits far above the years that follow.
