Keller Williams Southern Nevada
Yes, when you purchase a single family residence in Las Vegas you also own the land that comes with it. The escrow company will provide you with a preliminary title report that includes the legal description of the property and also a plot map showing the dimensions of the property.
Here is a link to local web site with ALL the MLS listings of the homes currently for sale in the Las Vegas area. This site is updated daily (unlike the "big box" sites like Trulia and Zillow which are only updated every three or four days and do NOT contain all MLS listings) so that you can keep on top of the market.
Hope this helps!
