Lol I couldn't stop laughing, dear OP.
So you mean there is no hard work?
The only truth about your rental property part is that, only those riches who suck the blood out of poor people and pay them their hard-earned money are the ones who create properties for themselves. Actually, they create empires, so they don't give a damn about renting that property to earn anything because they know how to get their work done through others' efforts while themselves sitting in an AC room, watching their employees do the job for them. Only those who know how to take work from others can succeed in buying properties for themselves and their families.

And about the marriage part, what has that to do with passive income? I'm shocked. If you think that your wife is an investment, then I believe you seriously need a psychiatrist. And yeah, if she's an earner like you, then it all depends upon how you guys manage your money and the most important thing - understanding between you two.
