@Tony Bryant Jr. congrats on starting down the path. The first step is to get that BAH working for you instead of someone else. If you start looking at properties, look at them with the eye for will this house pay for itself when you move to the next duty station.
House hacking is tough with a larger family unless there is an abundance of small multifamily homes in your area.
If you are handy and can put some sweat equity into the home you buy, that can be just as powerful as house hacking. Look for a house that needs some simple updates.
-Kitchen Cabinets (can you keep them, paint them, and change hardware)
-Bathrooms ( can you replace a vanity or paint it and put a new countertop on it?)
-Flooring (can you replace the ugly carpet with LVP or a new carpet before you leave)
-layout (learn to look for walls that are likely not load-bearing and see if you can change the layout). Just be careful. This type of renovation requires permits and lots of extra steps and isn't always feasible.
I stumbled into my first investment because I bought a great starter home that just so happened to be a great rental. But you can bet every primary home I have purchased after I have planned from day one for that house to be a rental.
