What help is available? (Bavaria)

Yes, the "good" thing about LABO is the low repayment, meaning in a few years we will earn more.

Our problem is, we live in a 3-room apartment and it is slowly becoming too small. In addition, the responsible school is not an option for us.
We have looked a bit at rental houses, but with 1100-1500 cold rent I am clearly above the repayment of a loan.

In addition, the responsible school is not an option for us.

Do you still have a school district obligation?

Around 25k

And basically the financing would be 20% equity +

So if I roughly have a loan amount of €450k in mind

Even if it were only 15%. How do these numbers fit together? Has so much changed?

Understandable, you want to desperately sugarcoat and calculate everything. There is also the possibility to rent a larger apartment...

I don't believe a purchased house would be overall cheaper than a rented property... with a house, besides the installment, there are many more costs coming at you... maintenance reserves (roughly calculate 1% of the house value per year -> with a house of €300,000 that’s already another €3,000 each year, and that is conservatively estimated). Then come the non-allocable additional costs, etc.,

Maintenance reserve (roughly calculate 1% of the house value per year -> For a house worth €300,000, that is already another €3,000 every year, and that is a conservative estimate).

However, that is far above what banks, as well as the Association of Private Homeowners, or even the Ministry of Construction, consider:

The Association of Private Homeowners goes beyond this recommendation with one euro per square meter and month and sees no reason for a tiered system based on the age of the building

Per year:

[*]for houses up to 5 years old: 4 euros per square meter
[*]for houses up to 10 years old: 6 euros per square meter
[*]for houses up to 15 years old: 7.50 euros per square meter
[*]for houses from the 16th year of construction: 10 euros per square meter

In principle, anything from 0.5€ to 1€ per sqm per month is fine; not too little; and it is also what banks consider in their calculations.

: How do you come to the 1% rule?

Have looked a bit at apartment buildings, but with a cold rent of 1100-1500, I am clearly above the repayment of a loan. This is a misconception!

: How do you come up with the 1% rule?

According to your calculation basis, that would be a reserve of approximately €28,000 in total for a 150m² house over 25 years.... After 25 years, you have an issue with the windows, the heating needs to be completely renewed, bathrooms need renovation, possibly the exterior facade (plaster), fence, shutters, floors, the roof still has a bit of time but is coming.... And these are just a few exemplary cost drivers... how you are supposed to manage maintenance with €28,000 over 25 years.... then you have an enormous maintenance backlog and the value of the house drops dramatically.

1%, because: house lifespan of ~100 years corresponds to 1% per year... an incredibly conservative assumption, in reality over 100 years the average will certainly exceed 1% ;)
