Finally getting started

Hi. I'm a newbie and want to do assignments in Texas (where I live). I'm ready to contact real estate agents now after reading 30 Days to Real Estate Cash and have a question: is it better to call ReMax or Keller Williams and talk to the agents or should I do it like Matt suggests and send faxes to all the local real estate companies and have the agents that are hungry come to me?

Also, when the agent asks how am I going to finance, what exactly do I say?

I have a sister-in-law who is a real estate agent but she is not with Remax or Keller Williams. Should I try and work with her?

Feel free to PM me. Thanks in advance!
