I want to ';flip'; a house / rehab / finance question?

I currently own my home (mrtg)... I have credit score 660 or so as does my wife.. we want to buy a house to rehab and sell.. buy for $60k, invest about$15k- $20k , should sell for about $110 hopefully...... What is the best type of mortgage we should get to purchase the home as an investment property with no $ down if possible......
