Investor Funding Question

[Brandon Becsi]

Trying to raise 500K to buy sell homes that we will purchase for 30k-80k and refinance or re-sell within 6 months or less. 

How can I raise this capital from say 3-5 investors? Just a standard promissory note? or what other options/security can I offer the lenders? I want to pay interest of 8-10% while using their funds. 

My 2nd goal will to be raise 2 million after I prove myself with this first 500k and use that for about a year.
