What is the criteria to use in your investing plan?

[Edmundo R.]

OK, I'm a newbie at this stuff @Edmundo R., I mean really green! I am putting my investing plan together, following Brandon Turner's suggestions from his getting started presentation. In the plan he suggests defining your investing criteria to include loan to value, cash flow requirements, maximum purchasing amount, maximum rehab amount and maximum time frame.  I;m not sure where to begin here, does anybody have any suggestions whether there is a recommended base to follow, or direct me to other educational resources that can help me with this part? Thanks.
