Alternatively i could go for being a real estate broker and try to get experience in actual real estate without putting too much of my own skin in the game.

Play the long game and focus on rent and home price appreciation.

Real- Estate  is a lot tougher game now because of technology now allowing buyers, sellers to access the market using the internet without using agents but  you do have hot areas that can support  more bodies .

As you have mentioned in the past, you should not put more than 10-15% of your money in one investment - so if you have $500k and want to throw $50k ok - but it still hurts. if its your first and only 50k, there are plenty of other opportunities out there to get in the game for lessFor many - Goes back to greed and FOMO as well, last few years everyone and their brother wanted to jump in on the STR and MF space because of these great returns - no different than NFT's and bitcoin before that, but when something moves up quickly, it typically drops pretty quickly as well.

Not know what Eddie Speed is all about, is there a game plan you have for notes?

Playing an appreciation game can be risky.

Hey Ximei,I totally understand wanting to maximize the impact of your initial investment, and if you're open to taking on a bit more complexity, the BRRRR route can be a game changer.

In any partnership you can't just cut a check and hope for the best especially if you're providing the money and the other partners don't have more than their time in the game.

Cash to invest (enough for deposits, skin in the game lenders want you to have, closing costs, carrying costs, and to kick off rehab work).2.) 

hope this helps. turnkey might be a good fit for you. but real estate is a long game.
