I'm selling one that's in Grand Prairie, but Arlington ISD. Address is 4543 Buckingham Dr, 75052. There's a mini open house tomorrow (Tuesday 4/2) from 8am-11am, but you can set up a different showing by replying to the Craigslist ad.
I also have one in Arlington but 76012, 2003 Arborcrest Dr. There's a mini open house there as well tomorrow 4/2 from 1pm-4pm (the mini open houses are happening while we get inspections). I grew up in that area so I think it's nice, but take a look and decide for yourself.
Both of these have an asking price of $129,900, which is quite reasonable in those areas. If you're willing to fix these up yourself, you get a great deal.
I'm not a broker or agent, but I am a real estate investor in Tarrant County. Get a realtor who knows the area, has experience, answers your calls, and shows up on time with a good attitude. It's not so hard to find, but just basic requirements, and they should be able to guide you on the lending rules / requirements.
