Denise Richards Slashed Hidden Hills House Price for 'Housewives'

Denise Richards isn't about to let a little thing like her zip code keep her from joining "The Real Housewives of Beverly Hills" ... which is why she slashed the price on her Hidden Hills mansion to move.

Sources close to the situation tell us Denise's motivation for lowering her asking price on her 6 bedroom, 8 bath crib was to get outta Dodge ASAP. As we first reported, Denise reduced the price by almost $1.3 million back in October. She dropped it even more this year and finally sold it last week for $4.995 mil.

Why the fire sale? Denise's neighbors bitched nonstop about filming back in 2008 when she had her reality show, 'It's Complicated' -- so much so, the property management company banned all productions.

It's widely believed Denise will join 'RHOBH' for season 9, so she'd need a new place anyway. No word where she's moving to now that she's unloaded the mansion.
