Don't mind. I don't buy him a chateau or penthouse, I am by no means rich, but I would need to pay rent for him for a room anyway when he leaves for university so why not buy an apartment instead? A reasonable 1 bedroom apartment starts ar
ound 50000 euros here if you start looking early. and if you don't buy from real estate agents which is still possible here there are less fees. As an young adult he gets a good rate. You can get a credit with only 10% down-payment here. So imo this is possible for anyone. That's the way I started, after a couple of years I sold it and bought a 2 bedroom, then a small house and then a bigger one and so on.
It it quite alot to organise and plan and manage and also you have to learn alot on the way, but if I could do it anybody can. I guess that's how SJ parents did it and now with 80 Isabelle has some assets she can live on. I believe that was the plan with the chateau, too.
Though I must say I prefer SJ not petting the animals all the time. Animals don't need to be stroked all the time, especially cats. if they need attention they come. Better leave them alone, you are not an animal lover just because you pet them all the time.
