One of the first if not THE first question you should be asking yourself is: What is my exit strategy?
If I buy/lease/control this property, how will I get paid?
The days of Carleton Sheets/Bob Allen/Get into the property at any cost, any way because it will cash flow every month and appreciate at 5%+ a year are LONG GONE.
This means that you need to do more due dilligence BEFORE signing up a deal. A motivated seller is a required BUT NOT SUFFICIENT condition.
