All to add on to @Matt Greer's excellent run down of the Fayetteville market, I recommend that you have a clear understanding of the tenants you want. This will help you narrow down the type of property and area that you should invest in.
For example, Fayetteville's rental market is dominated by military members. Get to know their needs, how those needs change over a career, and you'll really be able to focus your investing. Fun fact, military families have a lot of "stuff", so properties with extra storage are appealing.
To illustrate my point further; a junior NCO or officer without children may prefer to live close to base. Neighborhoods off Reilly and Yadkin Roads are excellent choices.
Fayetteville has very few good schools, so a mid-career/senior NCO or officer with children will be interested in the Jack Britt and Terry Sanford school districts.
My examples are simply to illustrate that knowing your target consumer will absolutely help you define your real estate investments.
Best of luck to all in 2019!
