Real estate purchase contracts

[Daniel Banks]

Hello Bigger-Pockets Family,

I'm new to real estate investing and have tons of questions through which most are answered through BP's podcast and you tube channel. One question however that I have not been able to find a straight answer to is,  for a person like myself who is interested in following David's Greene advise and investing out of state, how do I obtain valid purchase contracts for the markets I intend to operate in? After doing a bit of research on purchase contracts I know I need to make sure I'm covered but, I would love to know how more experienced investors are going about this. My goal is to find value add properties including wholesale deals to help fund buy and hold investments.  

Thanks in advance,

Daniel
