Sunrise Manor is a large area; as in all areas, some neighborhoods might be considered more desireable than others, depending on the needs and tastes of the homebuyer.
I myself have lived in the Sunrise Manor area for 9 years, close to Sunrise Mountain. My daughter and her fiance, both attorneys, just bought at the foot of Sunrise Mountain as well. The Upper East Side is populated with custom homes on 1/2-acre plus. It's somewhat rural in nature, and the residents here love the lifestyle and the Strip and mountain views.
If I can answer any specific questions about this area, please feel free to call or text me at 702.279.2466.. One of my agents currently has a 2600 s/f 1-story custom home built in 2005 in escrow that may soon fall out.
