Hi Keith, That's a big question but I can see you've thought about it. This is an exciting step but I think there are some important details about you that will factor in.
You didn't say anything about a spouse or kids or a job or handyman skills. You also didn't mention if you like Herriman or would prefer another location. Herriman is a good area with new schools, great parks and lots of growth. I have a 4 bed, 3 bath home there that rents for $2100 per month.
Most newbies with a good, full-time job and a great VA loan could certainly do well with an SFR in the south end of the valley that could rent as a duplex. If you can, live in the basement and rent out most of the home. With the right place, you could get nearly $2000 per month and almost cover a $350K mortgage. SFRs with a basement apartment are fairly easy to find or create, and very easy to sell.
If you've got some handyman skills and bought a Fixer-upper "duplex" home, you might be able to create some equity pretty quick and pull a HELOC within 6 months or so and use that as a down-payment on another rental.
That's my 2 cents. Have fun out there!
