Best use of investment money??

[Mark Lord]

Ok, so I know this topic has come up quite a few times. And I have read a lot of the responses. But every situation is different so I decided to ask your opinion based on my situation.

I'm looking to invest. I have roughly 25-30k to do so. I have a full time job that pays well, but I'd like to eventually become a full time investor. 

I want to know what the best use of my money is? I'm not looking for the "get rich quick" plan. I understand it takes time. But I'd also like to use any income I do earn to reinvest. So the more money and the faster it comes, the better!

Should I be looking at buy and hold rentals (SFH or Multi-Fam), flips, auction homes, lease to owns, etc...I've read a lot of mixed reviews on wholesaling so I'd rather not get into that.

How would you use this money? What has the highest earning potential?

Any help would be greatly appreciated!!
