Hey @Kathryn Bond!
I would definitely say this is house hacking, as you are purchasing and living in a home with the intent of making it a rental. What you are doing is what my wife have been doing, as to why we are also on rental number 3.
Focusing on areas that will appreciate well is super important, as equity down the line becomes a huge game changer when growing your portfolio. As it was mentioned before, I would reach out to local investors, folks who have property management companies, and find out the market rents, vacanies, and demand for the type of homes you are purchasing. For example, here in Boise a 4/2, 1800sqft+,3 car garage will offer the highest amount of market rent, is the most popular home to rent, highest quality tenants and they average staying there for 4+ years.
The difficulty is always going to be whats "most comfortable" for your family and what property will provide the highest return/ROE to help build a life of financial freedom for your family. Hopefully this helps and good luck with your next steps!
