Humidity in basement apartment

Well, if you pay the top tax rate, the net is more like half. That's just how it is.

What is the return on the cold rent of this apartment in %?

Do you want to sell it immediately again? Have you thought about capital gains tax?

What is the yield of the cold rent of this apartment in %?

Net cold rent 5.26%

Do you want to sell it off immediately again?

Preferably yes. Who gives me the guarantee that something like this won't happen again? More than one year's rent needs to be paid for renovation here.

Have you thought about capital gains tax?

Yes, thought about it. But irrelevant, as I'm not really making a profit and if so, only within a range that is not proportional to renovation work etc. I bought the apartment for 85,000.

Understood.

You can't buy anything with the reports.

You can also determine yourself with a measuring device whether the moisture is superficial (only wallpaper) or deeper (plaster). Incorrect ventilation should only lead to surface moisture. Moisture in deeper layers usually has other causes.

With wallpaper, the affected wallpaper must be removed immediately and disposed of.

No one can promise you that it won't happen again if it is due to ventilation. In my experience, talking and giving advice on how to do it correctly helps many people (unfortunately not all). Hardly anyone deliberately brings mold into their living space.

Possibly a basement apartment with generally cooler exterior walls in the summer (temperature difference between the wall and the air brought in by ventilation is greater) is also more sensitive; I have no experience here. Cool wall + furniture directly in front + summer air is simply not a good combination. Unfortunately, there is no information anywhere about the wall temperatures...

Whether you sell or rent again after renovation is your decision. Selling is certainly less stressful.

From a purely economic point of view, your return on equity declines if you renovate with equity and then rent again. Only you know from what level to what level it falls in your case. And also whether it is worth it to you.

Whether you sell or rent it out again after renovation is your decision. Selling is certainly less stressful.

Yes, the apartment is also 60km away. I simply can’t take care of it so intensively. I probably imagined it too naively.

Purely economically viewed, your return on equity decreases if you renovate with equity and then rent it out again. Only you know from what level to what level you fall in this regard. And also whether it’s worth it to you.

Economically, it’s obviously not good. But I also don’t feel like having the same problem on my hands after four months. I need to focus on building my own house now and can’t afford such side issues.

The apartment has now been renovated. The expert came by again after it was freed from mold and stood empty for two weeks. He says he can now exclude with 95% certainty that it was due to a construction defect.

The apartment is now going back on the market. I have no desire for something like this to happen again. I can hardly control the ventilation behavior and, in case of doubt, it is also difficult to prove that the tenant is at fault. Better an end with a fright than a fright without end. I will exit with heavy losses, which I really can't afford during our house construction. But there's no use in it.

Thank you for the feedback. I think that your case is not that uncommon at all.
