newbie looking for more info on DFW rental property

You will need to get familiar with the foreclosure process and the exemption status in detail for the state of Texas. Next, you will want to see the Sheriff's sales for the county you want to buy in. It is important to note things like landlord-friendly areas or tenant-friendly areas. There are tax foreclosures and REO or bank foreclosures. Always know the ramifications good and bad of obtaining either. Most properties for most counties' tax sales/foreclosures can be found at https://www.pbfcm.com/ and http://taxsales.lgbs.com/ as well as the county. These lists are different and will not be all tax properties you will see at the auction. Why? you might ask, the reasons vary greatly and may be relevant to you and they may not. Your risk is greatest when you are ignorant or uninformed or both, make certain you are neither or harbor as little of these as possible. You will need to register with the county to bid. You will have to do this in most cases at least a week prior and don't be surprised if a great number of the properties fall off before auction as this is common. You need to search tax records and property records for anything you want to buy and I suggest going through this entire process and attending a couple of the super Tuesday auctions before you are ready to buy to get an idea of what you will pay etc. It works you can get what you are looking for but you will have to do your homework and once you have all of this down and understood I would point you to the idea that everyone is better off if you can get the current owner to a deal in advance of the foreclosure. This is a very nuanced thing to do and is done by many disreputable people as well as many well-meaning people. It is hard and it is work but its a great return if you have done your homework and you would be better off betting on the Cowboys to make the Superbowl with all your money if you don't.
