Construction financing - How will it change in the future?

The fact is often: What is due in rent is apparently enough for the landlord to pay off the respective property within a humane period (25-35 years), including all ancillary costs, insurances, maintenance, taxes, and so on.

There are studies proving the exact opposite.
As a rule, privately rented properties mostly have a maximum return of 2%, with complete exclusion of all risks and time expenditures.

I often need a kitchen even when renting, and furniture anyway.

We moved into the rental apartment and purchased a kitchen for 10k. In addition, the complete furnishings cost about 15k. But it also has its advantages since we don’t have to buy all that again for our own single-family house.

Well, I don’t know what prices are like in your area, but where we are, we’re now at about €10/m² cold rent. That’s €1,200 for a 120m² apartment. I can easily manage that payment for a house with 120m² as well.
Then you have additional costs (yes, for a single-family house surely more than for an apartment) on top. But I don’t find that naive.
Especially since with a single-family house you end up owning property.

It looks similar in our region. If anything decent is available, it’s rented out in no time despite €1,200 to €1,400 cold rent. If I spend that amount on financing something of my own, it adds up to a nice sum.

Not at all. In regions where 1.2k to 1.4k cold rent properties are gone in no time, you don’t buy a house for 350k either, at best a heavily renovated or even needing renovation house. Then we’re talking half a million upwards for a normal single-family house or semi-detached house, and the amount mentioned above is not enough to pay that off in 30 years.

A recurring topic. You can compare numbers endlessly and justify it in both directions:

My favorite comparison is my old cold rent versus the interest burden without repayment, because repayment is asset formation. Calculated this way, I save money every month by buying instead of renting, even though I increase the area from 100 to 150 m². And since it feels so nice in this bubble, I don't allow any other calculation method.

Not at all. In regions where 1,200-1,400 rental properties (cold rent) are snapped up in no time, you won’t buy a house for 350k either, at best a house that needs major renovation or even refurbishment. Then we’re talking about half a million and up for a normal single-family house or semi-detached house, and the amount mentioned above is not enough to pay it off in 30 years.

Well, it’s not that much less either. Depending on the terms, with 1,400 you can manage half a million in 34 years.
The difference isn’t that huge.

I once looked for fun for a four-room apartment to rent in my city, there was only one offer that would have been an option. It would have been in a three-family house, about the size of my (small) house, with a share of the garden. The whole thing would have cost me only €100 less per month (cold rent) with a parking space than my single-family house. And I also pay it off accordingly. In my case, it is clearly "forced savings."

Recently, I leafed through the additional costs statement of my last rental apartment, 70m² panel building. The property taxes charged to me were about 80% of what I now pay for my house. I almost couldn't believe it...

Presumably, you can invest your equity (if you have any) at a higher return than in a self-used property. Not to forget are also the acquisition costs, which simply "disappear." When real estate transfer tax is due on the entire property and a broker also takes a cut, quickly up to 1/7 of the property value can vanish without any visible countervalue. (In my case, with that money, I could have rented the aforementioned apartment for about 2.5 years... or I have to pay off for about four years until the capital created in doing so exceeds the acquisition costs.)

Within this framework, everyone must then decide for themselves whether they want to take the step to their own property.
