House and property €284,000 financeable?

But that has nothing to do with the amount of the rent. The higher the rent, the longer the period to save equity, nothing more, nothing less.

For example, after deducting all ongoing costs i.e. rent, daycare, dental insurance, gym, telephone & DSL, installment for the land, I personally have maybe 30-50€ more per month, nothing more. I do this solely for the sake of the saving rate, to achieve a loan-to-value ratio below 80%. My wife is also on board with this, so after 1 year of saving we have reached our goal.

So it does have something to do with the amount of the rent after all
The problem at the moment is the enormously rising construction costs every year.
With a low saving rate, it is currently partly impossible to increase the equity ratio at all...

I know that we are lucky to pay so little rent. For that, we have had to accept compromises in the quality of living over the past few years. Two-room apartment, poorly laid out, in need of renovation (old unattractive floors, sanitary fixtures, kitchen). We accepted that because owning a house is our dream. So it’s not as if we have only benefited . That’s why I’m all the more looking forward to my new, beautiful house with (for our standards) a lot of "luxury" .

We live in the third most expensive city in Germany, and pay 900€ warm for an average 3-room apartment

Sure, that is clearly more than what we pay. That you can’t save 1400/1500 € monthly under these circumstances is of course logical. Still, at least 500 - 600 € a month in savings should be possible. Just consider: If you build a house and need such a high loan amount (full financing, rather 110% financing), then your rate will also be at this level (that is rent + the aforementioned savings). And you have to be able AND WILLING to manage that permanently.

So it actually does have something to do with the amount of rent

If you look at it that way, then you would have to say that saving makes no sense at all.

However, here you have exactly the example where you can see what saving would have brought. With €60k equity, this discussion here would have been a completely different one.

With a low savings rate, it is currently often not possible at all to increase the equity ratio ...

So, it does make a difference whether you have a negative equity ratio (meaning you cannot pay the "ancillary purchase costs" out of your own pocket), or the equity ratio does not really grow because the costs are also rising.

Of course, you can also save up later, there are definitely banks that go along with that; but you have to be honest with yourself and put more than just €1100 on the table every month:

We could easily afford a monthly rate of €1000 - €1100.

So, just for the subordinate financing of €35K, €300 per month are needed (and then it is not even fully paid off after the fixed interest period; €12,000 are still open after 10 years).

That leaves €800. That takes you about as far as €250,000 (however, in my view, you have to "trick" a bit and only assume 1.5% repayment, or be honest with yourself and take 3% repayment; then €180,000.

And by tricking I mean the fact that otherwise you would still have €180,000 remaining debt after 15 years.

Makes a budget of €215K or at most €285K. That is far from €450K.

Also, a new build is significantly riskier than buying something existing.

So a nice condominium would definitely be more feasible.

Sure, under certain conditions, saving makes no sense, at least not for purchasing real estate!

It is no coincidence that the typical real estate buyer in Germany is statistically over 40 years old and has already inherited.

I agree with you that it is absolutely sensible to save the incidental acquisition costs. However, these naturally also increase annually due to the higher construction costs at present. Once this goal is reached, 100% still has to be financed ...

However, of course, the current annual costs also increase due to higher construction costs. Once this target is reached, 100% still have to be financed ...

But this does not change the fundamental problem of the OP spending 1100 for the installment Max. Assuming he only had to finance 100%. Then Max would get about 250K-340K far.
