@Sonya Gulka DFW is a good market for appreciation right now, but also very competitive. To @Bruce Lynn point, the rents are not high compared to house values right now - shortage of supply is driving up the prices. I have found better numbers with smaller properties - 1100-1300 square feet. Find one of those in a desirable elementary district and you’ll be ok (but also face competition in the bids).
You may know this already, but out-of-state investors are also sometimes surprised by Texas’ “high” property tax rate (but no personal income tax). I don’t know exactly but on that $350K house in Plano I’m gonna guess property taxes are in the $7k a year range. So you are looking at ~$500 a month just for that. Generally taxes will be lower on the smaller/less expensive properties at a greater rate that the rents will be cheaper, if that makes sense.
Hope that helps. I am in Arlington so if you ever want some “boots on the ground” to look at a property around here, I’d be happy to help out.
Good luck!
