Las Vegas home investing

Just visited a friend's home bought last year, so I am look at the investing possibility of Vegas property. But lack of industry info, I just did some research from internet.

Here is the ZIPs that has good public schools and its crime ratings:
89106, 7
89101, 7
89149, 5
89123, 4.5
89144, 6
89131, 6
89122, 4
89129, 6
89107, 7
89138, 6.5
89135, 3.5

The problem is I am not familiar the location of each of those ZIPs. Have to wait for more info.
