House found - financing possible?

Hello dear ones,

due to acute uncertainty, I registered here today to get advice regarding my private project.

Project:
Purchase of a semi-detached house from a private seller, built in 2013, 10-year-old gas condensing boiler with 2x solar, 120 sqm living space, 410 sqm plot in 26188 including kitchen, carport, and conservatory for €329,000 (final negotiated price).

Basics:
She (31), he (33) with son (5 months).
Nothing will be inherited, our equity currently amounts to a measly €76,000, of which I would like to contribute about €56,000 (corresponding to 89.87% loan-to-value) to the financing.
I have attached our household budget as a JPG.
It contains all our costs (average last 12 months).

Concerns:
My wife has fallen in love with the house and would like to move. I can also well imagine living in that location.
Since we will not inherit anything and have had to save everything ourselves with great effort, I am now starting to have doubts. Politically and economically, a lot is happening right now, like always.
We have summarized our costs very precisely in the calculation (yes, there are high items included).
The present financing offer at 4.57% nominal interest with €56k equity and approx. 30 years term comes to €1,500 and leaves a positive residual amount in the household budget of ultimately €1,600.
That is basically only for reserves, retirement provision, repairs – but it still worries me because I currently have significantly higher savings amounts.

[*]How do you see the overall situation?
[*]Would you do it? If not, what would you change or why wouldn’t you do it?
[*]I am good with crafts, so I could also imagine an older house where you have to do a lot yourself. Unfortunately, the prices for single-family homes are still too high for me and I hardly see any price changes in our region so that we can find something inexpensive. How do you deal with that?

I am very risk-averse and like security. This long term confuses me a lot and I am afraid of making a wrong decision for my family that will lead us into a financial fiasco.

I would be very happy to receive answers.
Many greetings from the North

1,600 rogues remain after deducting all fixed costs including 2 cars and food... what is supposed to happen there?

I don't see any financial problems now. Rather uncertainty. What are your concerns regarding [Zukunft und Sicherheiten]? What are the fears?

Thank you both for your answers, which have already reassured me somewhat.

I come from a simple family and am the first to go to university. I saved everything myself, paid for my studies, etc. I'm simply afraid now to become so dependent for such a long time. I am not a fan of long contracts (mobile phone cancelable monthly, leasing max. 12 months, etc.). Since I have never bought anything this big before, I am rethinking everything twice.

among other things: Is the duplex worth the price? Will it possibly cost only half in 2 years? What about gas, we have no way to build a technical room there (heating in the attic), so a heat pump will be difficult in the future

If you’re not a fan of long commitments, you unfortunately have to do without property ownership. And I’d rather not tell your wife that like this(!) ;)
It is the nature of property acquisition that you bind yourself to a place and also to a loan for a long time, at least for most of us.

Whether the semi-detached house is worth the price can only be told to you by an expert who looks at it in detail. You should definitely get one to check it out. I don’t understand the fear of gas at all, because if gas becomes unaffordable, 50% of all Germans have a problem. If anything is "too big to fail", it’s the gas heating system. A few heat pump owners can’t hold a candle to that.

And regarding the value of the property. Are you buying it to live in? Or are you buying to speculate? If you buy it to live in, the value in 2, 5, or 10 years plays a minor role. Sure, in 2 years the house might be worth 30% less. Or it could be worth 100% more because interest rates are back at zero level.
It’s like with children. Those who wait for the right time will grow old alone.

You have already included BUs ... some BUs even offer the possibility to adjust them accordingly in real estate financing (in case it is still not sufficient). Otherwise, really finance for 30 years? Ok, if you want to be on the very safe side. Otherwise, it might be worth considering that after 20 years you have a significantly lower remaining debt and inflation/wage increases over 20 years will probably also help with the loan.

Is the house worth it? An expert is definitely advisable for such an investment. Or get an impression through a price compass from, for example, McMakler or something similar. 330,000 for 120 sqm from 2013 including the land ... it won't be in the middle of nowhere, but it doesn't sound too bad.
