After seven months on the market, the price for Annie Potts’ celeb-pedigreed estate in the San Fernando Valley community of Tarzana has plummeted from nearly $6.5 million to just under $5 million. The not-quite 1.5-acre spread, previously owned by “Marcus Welby, M.D.’s” Robert Young and, later, Robert Wagner of “Hart to Hart” fame, was acquired by the still-working “Designing Women” star in the latter days of 2003 for about $2.5 million.

Current listing details show the circa-1930s, single-story Spanish hacienda-style abode retains copious authentic architectural details, such as paver-tiled floors, plaster walls, vintage tile bathrooms and exposed ceiling beams. The main house has five bedrooms and 5.5 bathrooms in a tad under 6,500 square feet, while a detached guest house or staff quarters adds another bedroom and a bathroom. Generous formal living and dining rooms are joined by spacious family-oriented spaces that include an oversized family room with custom stained-glass window wall, and an exuberantly colorful tiled kitchen that opens to a dining area and lounge with traditional kiva-style fireplace and modern-minded steel-framed French doors.

The estate’s grounds include a variety of verandas, loggias and sunny terraces, vegetable gardens and vast lawns, a full-sized lighted paddle-tennis court and two swimming pools — one of them for lap-swimming just outside the master suite. With their children grown, Potts and her Emmy-nominated producer-director husband James Hayman plan to downsize and divide their time between L.A. and New York, according to listing agents Anne Burkin and Deedee Howard at the Agency, who also told us a primetime drama series star has shown some serious interest in the estate.
