Novice gopher??

Im new to this and trying to ease myself into the industry. I was recently at a seminar where I learned that certain companies pay you for supplying them with leads. More specificially they would be looking to buy seller financed mortages with xx amount of time left on the mortg ( i think less time left is better right?) and it is usually a balloon typ mortg. Does anybody have leads on this; a name or website and where i can start searching for these mortages?
Are the mortage records onlne or will i have to go to a courthouse or records location?

Thanks in advance for your help…love the site!

bump…am i on the right track?
