What are attractive returns for the real estate investor?

[Shannon DuPree]

Greetings, I am new to the exciting, involved yet rewarding market of real estate investing. I have several properties I am currently evaluating to be placed under contract. Single family homes, duplex, and homes within the Albion college area. I seek a win win for all players involved my sellers, and the  investors. I would highly appreciate feed back from investors on the matter of, "What % of return on your investment are you looking for that will get you active?" Any and all helpful feedback is welcome.
