Is a deviation in market value possible when selling real estate within the family?

Good evening,

I am wondering to what extent the current market value can be deviated from when selling a property within the family (parents - son)?
How much cheaper can the property be sold to me?
Is there a rule of thumb, such as up to 25%?

My parents are selling me a property, on which I plan to build soon. However, there is still a loan that can only be terminated or paid off in this way. Attempts to reach a different agreement with the financing partner have failed. Actually, the property was supposed to be gifted to me.

Regards

Don't understand the question?
Real estate transfer tax does not apply when acquired from the parents.
In my opinion, you can also set a symbolic euro.
But I also don't understand the situation.
Who has financing where and why does it contradict a gift?

I don’t understand either. Anything worth over 400k you have to pay taxes on or pay your parents.

Once again, a great regulation, you’re already taxed anyway, no real estate transfer tax, nor inheritance tax, you have to pay everything from already taxed income: 6.5 percent, thank you very much.

No, not a sore loser, I just downshift two or three gears.

And to accept it so fatalistically sounds very composed and cool.

But it contradicts the always promoted performance ideology that our society is supposedly built on... Work must pay off, support and challenge. I'll laugh tomorrow then.

Why? I have accomplished something, and later it will also benefit children and grandchildren. I don't want to bequeath my achievements to the state; they have received taxes, so we are even.
