Opinions on our financing calculation for home purchase

Hello dear community,

I have been reading along for quite some time and have now decided not to always just look for similar cases, but to ask my specific question.

We, my husband (28) and I (30), want to buy a house.

Current salary situation: 1500 + 3000 net = 4500 euros total net monthly
(tendency rising; however, there is a desire to have children, so about 1000 euros less per month for 1.2 years is possible...)
My husband has a permanent contract and I am a civil servant.

Equity of 100,000 € is available.

The properties that appeal to us all cost around 400,000 euros.

Now my question to you: Do you think we can afford this in the long term?

That naturally depends very much on how many expenses you have.

Hm, we have listed our expenses and currently come to living costs (all insurances, gasoline for 2 cars, mobile phone, landline, daily newspaper, groceries, shopping...) excluding rent of 1400 euros per month.

I have also calculated this for us (similar situation, but more net income). Without children, 300K, 400K, and even more are no problem. When a child arrives and costs increase, as well as the salary decreases, the world looks completely different. I no longer dare to expect more than 350K from us. So if children are an option for you, run all the calculations through again with that in mind.

Your financing requirement will be in the range of around 350,000 euros. Maybe you can get a loan with 1.5% interest over 15 years. With a 3% initial repayment, the monthly rate will then be a good 1,300 euros.

In addition, there are your living expenses and house ancillary costs (~500,-). That makes 3,200 euros, so it should be fine. In my opinion, the risk usually lies in underestimating your own living expenses. If you haven't badly miscalculated that, it will work out, even with 1,000 less net. With the current salary, you should be able to cope with the additional costs due to double financial burdens during the construction phase.

I would disregard higher living expenses due to a child; by then you will probably have somewhat higher salaries, there are tax advantages and allowances.

At the moment, my mind also tells me that it would be doable. But since we don't have children yet and don't know how much that will change us, it is difficult to estimate how it will be and what additional monthly costs will come... Several of you must know this problem, right? Most people buy a house because they want a family or already have one. How did you experience it? And: Are 500 Euros in additional costs for a single-family house roughly the normal average?
