Real estate investing platforms

[Nathan Phan]

Hi all,
I know I have already asked this question, but I haven't got any real answers. Basically, I am looking into investing in commercial real estate, but don't have that much money. I have discovered Fractional investing which supposedly allows investors to access traditionally expensive assets with lower buy-in amounts. The emergence of platforms like Arrived, Here, and REalpha, where buy-ins can be as low as $10, has democratized investing to a broader audience. On the other hand, there are still established models like the GP/LP structure used by prominent figures such as Grant Cardone and Brandon Turner, where buy-ins tend to be higher, typically starting from $5,000 to $10,000. There are even platforms like Fundrise. I am so confused on all of these startups? Also, why are most of these startups like Arrived, Here, and REalpha, fractional... all focused on residential real estate? Why not commercial real estate? Open to thoughts, ideas etc...
