Joe's Jeans Owner -- Sells House A Skosh Under $10 Mil

Joe Dahan -- founder and creative director of Joe's Jeans -- knows all about selling retail ... he just put a hefty price tag on his ultra-modern Hollywood Hills mansion -- $9.995 million.

In case we have to hit you over the head ... Joe used the psychology of retail sales ... pricing the house a teeny, tiny bit under $10 million to make it seem less expensive.

The 5-bedroom pad was designed by famed architect Hal Levitt ... it's even got an organic vegetable garden and a greenhouse, in case you're a pot enthusiast.
