Investing Deposits? Risk/Reward?

[Syman Scarpellino]

Hey BP Community, 

My rental portfolio is steadily growing (still pretty smalltime), I am up to about $20,000 in tenant deposits. Thus far the money just sits in an account, as its not my "free and clear" money.

What do you guys think about Investing deposit money into the stock market? 

I am not suggesting putting all the money on a roulette table, or a meme stock like AMC or GME.

However, the idea of investing the money in a stable dividend yielding stock is an interesting idea.

Where would you guys invest it? Would you Invest it?
