You should also check into new homes at Harmony Homes Bella Fiore & Tremezzo Communities in the Lake Las Vegas Master Plan. They are a little above your stated price range but are well worth the look. Starting at $298,990 plans go from 2307 sq ft thru 4615 sq ft. - both communities are gated with security patrol included.
Lake Las Vegas is a peaceful Master Plan Community only 15-20 minutes from the strip. You can check out the community specific websites at http://www.bellafiorellv.com and http://www.tremezzollv.com or contact me direct at 702-324-9281 or email Mdutchess@HarmonyHomes.com.
There are many condos and homes for rent on a month-to-month in Las Vegas that will accept your two pets. I would be glad to send you properties to look at that will accept pets and show you any that you would like to see while visiting here.
I can assist you with rentals or purchases.
