Are there any people here who invested in real estate over the years and now live comfortably or luxuriously off their rental income?

I am 21F and have been curious about this for a while.
How realistic is this as a long term goal? I would love to hear about your journey

1️⃣When did you buy your first property?
2️⃣How many properties do you own now?
3️⃣What were the biggest challenges along the way?
4️⃣Does the rental income fully cover your lifestyle, or is it more of a supplement?
5️⃣If you were starting again at 21, what would you do differently?

I would also love to hear from anyone who has experimented with buying property abroad. What made you choose that market, how has the experience been, and would you do it again? i am interested in hearing both success stories and the realities that people do not usually talk about the risks, mistakes, lessons learned, and whether the live off rental income dream is actually achievable in practice.
