Typically the best / simplest way for sustainable mostly passive income is rental property. Lots of how to guides out there. Mortgage rates are really low at the mo if you want to leverage.
I did some calculations about owning your own apartment vs renting. At least in Finland with the current housing prices and interest rates, the difference in a 25 year period between owning and renting was surprisingly small. Personally, I'm happy to pay rent and have the money in more liquid assets as well as enjoy more freedom and being debt free.
I assume renting out would only be worse with the additional risk of having bad tenants.
Here in Finland, the status quo seems to be that you obviously save for your own apartment as the first thing. From purely financial gains perspective, I couldn't find the rationale.
But isn't it always good to own the property you live in ? If instead of paying $1000 a month for rent, you pay that $1000 a month for a loan for your own apartment you still have the same money to invest that you have now but you will eventually own the place you live in and free that money up. Of a big amount of that monthly payment will be interest, but at least not all of it is gone. This only works if you can actually finance a place for similar money as it would be to rent, which i am not sure of.
This depends on the country. Property isn't exactly passive income, when compared to other types of investments.
For example, in Belgium, stamp duty (a transfer tax) upon acquisition of a property is 10%. It takes a long while before you generate that back in rental yields.
