Buy a single-family house - mortgage a condominium unit and sell it later?

Exactly for that reason. Now there is no speculation tax that would be due later. In addition, the rent only brings you additional income that must be taxed. And last but not least, you can actually realize profits – and not just on paper. How is the market developing? How is the apartment being worn down by tenants?

LOL, how do you calculate that? Purchase price €220k – let's say €40k land portion = €180k for depreciation = €3,600.

Net cold rent €13k
minus depreciation €3.6k
= taxable at 40% = €3.8k taxes

Remaining €9.2k surplus minus non-allocable operating costs (property manager, etc.).

Of course, you can do it that way. On the other hand, you can sell and save €400k loan. At 1% interest, that’s €4k per year. So in the end, there’s a small plus if you keep the apartment.
But then there are maintenance, renovation, tenant turnover costs to pay.

Of course, this is just a very rough calculation, but it’s not a top deal.


Yes, fixed rate should be cheaper than variable.

He does earn income from the rental which is higher than the repayment of the apartment. Or am I in the wrong thread?

Yep. You are.

Option A: Sell apartment and financing "only" €300k with planned installment €1,500 Option B: Keep apartment and financing €700k with installment at least €2,700, but with surplus from the apartment of €250

Are you assuming the €2700/month ONLY for the house?
