I want to invest small amount

Please suggest me to invest small amount in real estate business.

How much is small? Like $500? There are options to do so with some online programs.

The Penny Hoarder had an article on Fundraise, which allows investments starting at $500 in real estate: https://www.thepennyhoarder.co…ney/fundrise-review/

Yes $500.

Check out M1 Finance App. I started using it in January 2019 and have increased my savings there.

You could use small amounts through the STASH app.
