Sounds like a good plan to me.    The most important thing is playing to your interests and strengths. If you want negative commentary:

Real estate was considered a solid investment pre 2008 subprime mortgage crisis. Back when most could not remember a time when real estate had depreciated in value & thought it was impossible for such a thing to occur. Rent and real estate prices are declining in US regions like california and new york which are hemorrhaging residents due to high taxes, high regulation and similar factors. While real estate and rent are increasing in states like florida and texas which may be experiencing an influx of new residents drawn by low regulation and low taxation.

The big question with real estate is whether we'll soon experience a fiat devaluation / hyperinflation event. If so when. And how long such an event might last. It could be worthwhile to keyword search "best performing assets during a recession". If indeed this pandemic could send us spiraling into a recession/depression.

In terms of generating passive income. There are many podcasts and youtube channels devoted to side hustles and passive revenue. There are small business owners who don't mind disclosing vital information on their ATM side hustle, in terms of how much revenue it generates, what the main difficulties are, and so on. Whatever your interests or mind there are related methods of generating passive income.

I have seen 3 foot tall fruit trees selling for $100 across the internet. Avocados, mangos, lychee, rambutan, etc. Like bitcoin, fruit trees and plants tend to appreciate in value over time. They might be considered a passive form of income requiring mostly sunshine and rain. Both of which fall naturally from the sky. There are avocado pits I threw into a compost heap last year that sprouted and are growing into 2 foot trees this year. I could never get $100 for something that grows that easily and plentiful here.

There are many opportunities everywhere. I literally just saw one browsing amazon of all places.

Good luck! Hope you succeed!
