Construction financing - mortgage instead of equity?

the rate for the 50,000 is about 300 euros - I honestly can hardly imagine a case where it would be impossible for us to pay these 300 euros even if everything really went to hell.

The thing with the vacation is the current snapshot - it just doesn't work like that with a child anymore.

The sockets are sufficient and everything else we want is done by my father-in-law (electrician).
The floors are well calculated, 55 net for the parquet and 40 for the tiles. Painting work is included, we could still do that ourselves, which would save us 6,000 euros.

that my parents aren’t starving. They have their house, worth about 700,000 euros, have shares in a well-running tourism business, my father receives an above-average pension, and my mother also earns quite well.
Money is not available because they are constantly doing things on the house, have two large cars, and are constantly going on vacation.

When everything goes to the dogs: separation, death, who knows: former affair of the partner shows up with 2 children, for whom retroactive maintenance payments become due / inheritance on the house is registered, whatever. All worst-case scenarios, which unfortunately are all much more likely than a disability for which you have insured yourself despite the low probability (!)

then you no longer decide, but the "insolvency administrator" of your personal insolvency decides where the €300 will go in the future, please keep that in mind.

Vacations with children are so much more expensive, you have no idea what family resorts cost.

Oh, €40/sqm for tiles? cute! You've been to a hardware store, but not to a tile specialty store, right? 30x60 and cut base tiles are enough for you? Never-ever! Even if you stay at the €40 tile price, additional costs for format- or pattern-related installation effort will definitely come, plastic finishing profiles? You can't be serious! Maybe you'd also like a shower niche tiled with mosaic? ... After your tile sampling, you will remember this post when the additional invoice for several thousands arrives.

Doing the painting yourself? You do know that painting work not only includes the coat but also sanding, filling, embedding fabric, etc., right? Are you sure you can do that?

The builder will not be particularly happy if an external, private electrician interferes with his trade, that's nonsense, sorry.

Please reconsider all this carefully.

Ok, if despite good income and high assets they don’t have "50K" left for you, then you should URGENTLY refrain from mortgaging their house.

Yeah, that doesn’t add up.
Actually very well off but allegedly nothing liquid.
For the €50k mortgage I would never involve the parents, the interest savings would be at most in the low four-digit range.
Do the thing, have the parents buy you the kitchen or something else, but keep their house out of it, that’s just a crazy idea.

I read your post yesterday and at first thought about just ignoring it, but now I can’t take it anymore: What on earth is wrong with you?

It is more likely that my partner’s former affair with two children is standing at the door than that I become unable to work? Wow! That statement alone is so outrageous that I seriously doubt your good upbringing. And even IF this absolutely hypothetical case were to occur, I wouldn’t be instantly bankrupt because of it – where would that lead us?! You can also sell houses!

Vacation – did you actually read what I wrote? Or did you just catch a few words and then start ranting? I wrote that vacations with children just don’t work anymore anyway, and you come at me with "you have no idea..." – again: what is wrong with you?!
Also, I NEVER mentioned that we want to do the painting work ourselves; on the contrary, it was about whether it was included or not! Reading helps immensely!

When it comes to the flooring, I really have no words left.
Who do you think you are to assume how intensely I have already dealt with such questions and whether I find something I like in that price range?

Unbelievable, really.

The interest savings would be around 0.6% in total, plus we would have to contribute only 10,000 euros of equity instead of 25,000 euros. That does make a difference.
So calling it a foolish idea means that the advisor from Interhyp is incompetent?
I already wrote why nothing is liquid, but of course, you can also just read half and then give your two cents. Always works.

For everyone who is really interested:
We were with the developer yesterday; our special requests do not lead to any increase in price. Only the sockets need to be reviewed in detail once more, but at first glance, there are more than enough included in the plan. So yes, everything is really included in the 430,000, even if some might not believe that

It is doable - but it wouldn't be anything for me
4,800 minus health insurance, minus installment, minus additional house costs, that would personally leave me with too little. Others manage with the rest for living expenses, savings, etc.
