Hey Bryan,
The DFW real estate market has exploded over the last 5-7 years. Due to a lack of inventory and low interest rates our market is very competitive. Like most major U.S. markets prices have continued to rise. Everything moves fast. If you've done a few internet searches you have probably realized that DFW does not have a lot of small multifamily properties. Those that are available are generally older and often located on the Fort Worth side of town. Just a heads up one of my clients recently lost a duplex to an all-cash offer that came in $52K over asking.
If you have the option to work from home it won't really matter. However, if you have to commute buy near the office. Traffic here is terrible. Not Los Angeles bad. Just an unnecessary layer of stress when you relocate to a new city. If you prefer North Dallas or the North Dallas suburbs you will find it easier to house hack a single-family and rent by the room. Hope this helps.
