Yes Im waiting crisis when i can buy finally land and Property everything is so expensive.
But war will make better prices in every bad there is something good war it's not good thing but at least you could buy something cheaper after war.
Are you plan on buying land in Palestine, Israel, Hamas, Iran, Iraq, or Lebanon, then don't buy land there. For the sake of your safety, but still, I know the land there will be way cheaper. I don't know about Israel. But if you are planning to buy land in Europe, then I don't think such a war will make any difference on such lands, although climate or crime change in the region can really make a big difference in price.
I once saw a video on IG in which a dude was saying he used to invest in a country, like buy land or other material stuff, but after the war like when the war ends and now the chances of another war are lesser, he said he has done this for his whole life. The idea is not that bad and might be profitable too.
