Starting out in Dallas/Houston/San An, need guidance

[Sanad NA]

Considering moving from Canada to Dallas as I've lived in the Coppell/Irving/Grand Prairie area and want to jump into real estate investing. Have attended a courthouse auction and been browsing hubzu, auction.com, etc, but don't know where to start. I can only use cash and am targeting a 100k budget, no interest will be considered, so at this point I'm thinking my best bet is to buy a rehab sub 100k house, fix it up and rent it out, and keep working until I can buy the second, third, etc in cash. Thoughts?
