Are you investing locally? Do you plan on managing the property yourself?
Memphis Invest has an arm that operates in DFW. You can send them an email and they'll send you the details of a few properties currently on offer. This will include a spreadsheet that runs the numbers on a few different financing scenarios. You should add some assumptions about vacancy rate and ongoing repairs (maybe 8% each) to arrive at a more realistic number than they're pitching. I'm not necessarily recommending you invest through the company, but I think it would be a good jumping off point. If you have a willingness to manage, renovate, or source properties yourself, you can probably do considerably better.
