@Kaylyn Dart: Congrats on surviving the Marine life! Army Veteran myself, and living in Colorado Springs for the last 2 years. As for your questions, the VA home loan is a great financing option for us as mentioned by the other two but has trouble with the strict guidelines for the property conditions. You're essentially looking for a Move-In ready home with minimum or preferably NO repairs needed which can be a difficult task in itself.
As a beginning investor, figure out the best option for you. If you're comfortable living with others, house-hacking a 4 bedroom (SFH) with 3 roommates could be the way to go. (As a Marine, it's a lifestyle I'm sure you're used to by now) If you prefer privacy, the 4-plex would be a better route, but know that these are even more uncommon to find in VA qualifying condition in the area. Competition was tough last year when I closed on my first home (4-bed SFH; House-hacking Currently) between homes that would qualify, and people paying above asking price within days of a new listing. If you have the opportunity to start now, I strongly recommend it because of the delays, searching, questions, walk-thru's, bidding, waiting, paperwork, etc.
In terms of areas in Colorado Springs, the Southeastern part of town near the Airport appears to be the lower income area with more affordable housing (under $200k), and the closer to Monument (North-side) you go, the more you'll end up paying for a decent home.
