Feasibility Single-family house - Cost statement / Financing realistic?

If I understand correctly, when you spread your joint annual income over 12 months, you have about €5630 per month of secure income. Even parental leave can be managed well with parental allowance, child benefit, and [SK3].

Considering the fact that you still have almost 40 years to pay off the loan, the loan amount is really the least of your worries here...

In my opinion, the installment would fit the income, but not the loan amount. I would go a bit lower here (possibly with a longer fixed interest period if you want security). As already mentioned, you have enough time to pay this off. I would set the theoretical loan term so that you are roughly finished by retirement. That results in an installment of about €1300. Why give up flexibility... you gain zero benefits from the higher installment except more stress when things get tight. If you really want to pay more off: special repayment.

If I understand correctly, when you divide your joint annual income by 12 months

Nobody calculates like that. Rather, special repayments are offered or included, which are supposed to be paid from the 13th salary. There was some kind of survey here once: one out of ten still had money for the special repayment, the others admitted that they more or less spent it on extras in life (furniture, garden, vacation). Therefore, do not include any extras or nice-to-haves in the monthly salary calculation.

It would be easier for the financing ;)

No, it doesn’t matter whether you are married or not. What is important to the bank is that the borrowers are split between two and the loan is not carried by just one.

When part-time work is added and later daycare fees, it gets tight.

In this respect, I would simply play through how it will be with child 3 and parental leave—so there are no surprises. And if you want to work full-time again, then probably with 4/4 (otherwise you’ll get the crying)… also calculate that sometimes. And don’t forget: additional house costs around 400€. Risk insurance is also included. If the numbers look tight, just build 20sqm smaller :)

Early repayment options are rather offered or included, which are supposed to be paid from the 13th salary. There was somehow a survey here once: one out of 10 still had money for the special repayment, the others admitted to having spent it more or less on extras in life (furniture, garden, vacation).

And this is exactly where the mistake in financing planning lies. Special repayments should not be planned in order to be paid from bonuses or the like. Rather, they should be used as an active tool to control the monthly rate. However, this is only possible if the rate has not been set too high from the outset.

1. You are still young and have a good 40 years to pay off the house. 2. He earns well with €3,000 net (tendency rising) and she also earns decently – if she then goes on parental leave, you can switch to 4/4 and his income + parental allowance + child benefit should be quite good. 3. You have saved a bit of equity, looks pretty decent so far. 4. You currently have "relatively" high expenses without a child – I think there's certainly quite some potential for savings there. 5. Later with children (so probably 2?) managing a rate of up to €1,700 --> Yes, that will be quite tight during parental leave I suppose. We have similar salaries and have already calculated this and probably have to reduce the repayment during the years when mom is at home full-time to about €1,300 - €1,500. But for the next 4-5 years we repay nearly €2,500 to "balance it out" again. Maybe that's possible for you too, depending on when you want kids? 6. I would basically always recommend flexibility in these cases --> meaning: repayment rate change up to 1% and special repayments of 5%. That way you can always vary if it gets tight or also the other way around :) 7. €420,000 with upgrading without a basement sounds realistic... Depending on what you want, maybe add another 10-20k – but I think that can definitely fit. Additional costs €35,000 – without a basement also realistic, maybe calculate another 5-10k as a buffer. Double garage €20,000 will be tight... We haven’t found anything suitable for a "standard 6x6m garage". Better add another 5-7k on top. The rest looks good and well calculated.

Do it, but start with less repayment. 2% is still fine for your age at first. If the woman earns well again after the children, you can increase it. Equity is high enough to do this with manageable risk. P.S. Where in BW are there still plots of land for 70€ BRW?

2% is still fine at that age for now.
If the wife earns well again after the kids, you can increase it.

I agree. That’s why I would also recommend high flexibility in the repayment rate.

I wonder that too :D

70€ is really low – even in the biggest "godforsaken places" around here, the BRW was over 100€.
