Owning a home is not the same as owning property which enables you to consume labor power for profit. Owning a home doesn't put you into the "owning" class when you don't employ people. Maybe if you can finish the remaining ~70 pages of the Manifesto, you can work your way over to the German Ideology. Marx and Engels were not the first to uncover the reality of class struggles in history, but they explained that capitalist production will reach a stage in its development in which the forces of production can no longer be contained within the prevailing mode of production. Capitalist production has never been able to offset its tendency to over-accumulate and produce immense waste, with little concern for effects on the conditions of workers or the environment. Humanity will be compelled by material reality to take means of production and dispose of capitalist society.
The 'socialist' examples you provide were either contained and isolated nations governed by a degenerated Communist Party (except for Venezuela) and in any case, never achieved abolition of commodity production or production of means of production.
Oppressed and oppressor class are the essence of class struggles throughout history, but under the capitalist mode of production it is the proletarian and bourgeois classes, so you can just say that (Bourgeois and Proletarians is the first chapter in the Manifesto).
I don't own property, and chances are, neither do you. A very small minority in society do. I'm willing to give my life for the revolution. I don't think history ends at capitalism.
