Where do you live to be able to buy a house in cash after 3 years of working? Where I live the average appartment is about 400K euros and the average house is closer to 500K euros.
Maybe you can find something for 250K if you really buy something small that needs lots of work. But you still need over 80K a year excluding taxes, probably closer to 120K before taxes.
Yeah I was thinking those Waltons have more money together then even Musk.
