Should I put up more personal money, or should I leverage much as possible?

In your case, you mention down payment which to me implies that you are leveraging this property with a bank loan.

Educate yourself...

I look forward to connecting with other like minded investors and continuing my education in real estate. 

@Marcus L Roberson I am a huge proponent of leveraging and the $21,000 could be used to finance a flip in your market.   

I have a few things to figure out - one being the infamous "all cash vs. leveraged" debate.

Unless you are just looking to buy a solid performing note and collect on cashflow, you may want to consider doing a JV with an experienced non performing note investor to educate yourself along the way. 

Should we go for those or try to find the ones who would let us use some leverage?

I graduate from the program after grossing 100,000.They Help set up my business planMarketing Education - weekly, & monthly , double deal, provide contractor list, forms,They pass on deals as well as funding ( haven't gotten details what the funding terms would be)   I listen to podcasts @Brandon Turner and read books that highlight the importance of getting a coach, however terms and condition are not discussed.

The more broad your education/licensing/certification on your resumé, the more opportunity.
