Auction.com leading to foreclosure auction in Dallas, TX, advice?

[Account Closed]

I'm residing in Canada but am a dual citizen and ready to pull a trigger on a rental property in Dallas, TX as I have family there who can monitor things when I'm gone. I'm not looking for a demolished house to make 70k on but as long as I can save 30k roughly off market value I'm ready to buy and just rent it out/ keep it for a while. Mainly looking in Grand Prairie area and Arlington. While browsing auction.com, Marshal and Hudson, and various other website it looks like they all just lead to a March 6 auction at the courthouse. I have about 12 houses I bookmarked; what is the process now? Should I call an agent or professional in Dallas and have them check the title, liens, tax situation, etc before flying out? The auction.com documents seem pretty legit, they provide title information, liens, comps, market value, etc. It seems like this is only a live auction. Looking for advice on how to approach this, I have no problem making the trip for a week or so. Thanks.
