89115 is not a fabulous area, however, it is close to Nellis Air Force Base. Typically the folks stationed at NAFB tend to rent a bit further west from that location, more around Pecos/Tropical, Pecos/Centennial area which is actually NLV. The entire city is under the same school district, however, again the quality of school/teachers just varies from one neighborhood to the other.
I would suggest checking LVMPD.com for crime statistics in the area you're looking as well as CCSD.net for information on school rankings in the area.
Also, you can checkout the neighborhood link I have provided. It has 10 of the more well known communities that would be good to invest in.
