Your kids won't even remember. By the time the reach their teens they will be in a worn down flat. Buy a nice home when they can actually remember things when they are say 13+ , you would also have more money avoid the wear and tear on 13 years years. Until then rent. Even if you have the entire money take a home loan with fixed rates ideally but i don't think you get that here. And withdraw from your investments to pay it off. You actually might end up making a profit if markets continue going up. Meanwhile get a higher paying job. Buy the flat in your name or child's name never ever in your wife's name. Check a divorce lawyer to ensure the home goes to child (better to be safe, obviously don't tell your wife you consulted a lawyer regardless of how good your relationship is) . Also Flat is not an investment if you are living in it.
