Liquid 15k to invest. Better to save it while I'm learning?

[Andrew M.]

I'm pretty fresh to investing, I'm in the middle of my first deal right now and it was a pretty odd one at that ( a rehab on a purchase option with a plan to use the rental income from the property to pay for the property itself.

The deal is finishing up right now and although I'll probably end up making very little money with it I have learned A TON and I am ready to start investing more seriously.

I'm pretty strapped for startup capital due to having extremelyy low job income but I do have about 21k in mutual funds right now that I could liquidate whenever I want and probabably have about 17 after taxes.

One part of me wants to liquidate it immediately and leverage it into a decent first property ( or two) but one part of me thinks that I should save this easy money until I have more experience and I'm less likely to squander it.

If i do save it, it could mean waiting years until I have a career which can provide that sort of discretionary income to start with ( I just graduated college and don't have any serious long term job offers yet).

So, I want to hear some opinions on how wise you guys think it would be for a young person to throw in everything theyve got with relatively little experience
