'RHOC' Star Kelly Meza-Dodd Says Her Sunset View Will Cost Ya $6 Mil

from 'Real Housewives of Orange County' is getting rid of some prime OC real estate ... and doing some high-priced flipping in the process.

Kelly and her husband bought it just a year ago for $3.575 mil, but they've sunk some dough into it ... doing a bunch of renovations. Check out what they've done to the 4,370 sq. feet of the place.
