Hi Mike, I'm the Market Intelligence Analyst here at BiggerPockets, and as someone who just moved across the country for my own house-hack, I feel qualified to answer this.
First, I wrote an article regarding this specific question, take a look if you're curious:
The 10 Best Markets for Your First House Hack
Second, if you'd rather do your own research, we created a simple "Where to Start" dataset that includes data such as population, price, and rent growth. You can find that here: https://www.biggerpockets.com/resources/market-data/where-to...
Third, my biggest mistake was not talking to enough property managers to fully understand the rental market. For example, in Los Angeles (where I'm from), rentals are always in high demand. However, in Fayetteville, AR (where I moved), the "leasing season" is in the summer. Demand for rentals is near non-existent in this specific town during the winter, and demand is extremely hot in the summer months. Because most units are rented in the summer anyway, the "median rent" here is basically just a reflection of the rents you can get in the summer, not in the winter (big oops on my part). This is something that even I didn't pick up in my data analysis, and I'm supposed to be the "market analysis guy." Some things you just learn by picking up the phone and talking to boots-on-the-ground.
Long story short, there are many markets that could work (you've alluded to some in your post, and almost every market already mentioned in this thread is a solid pick). But because you're house-hacking, I'd also account for "quality of life" if I were you. Some things matter more than saving an extra $200/month because you chose to live in a market you didn't necessarily like.
