At developer Michael Bolla and Michael Daniel’s luxe rental conversion, 436 West 20th Street, two-bedrooms go for $15,000 a month. At that price, why not buy instead? For starters, Bolla says “the cost of ownership living in a space commensurate [to what’s available] would be far more.” The entire townhouse was painstakingly restored and units come with Baccarat crystal chandeliers and paintings worth thousands of dollars. Plus, the amenities aren’t exactly pedestrian: There’s a butler, an in-house seamstress, and free monthly readings by celebrity psychic Roxanne Usleman Hulderman. Neither are the residents, famous types that are rumored to include a rock star otherwise known as Courtney Love. “Most of our tenants are short-term in nature,” says Bolla, who wouldn’t comment on who lives there now. As for Courtney? “Ms. Love no longer resides at the Mansion,” Bolla says. “Her apartment — the parlor floor with its beautiful George Smith antiques and furnishings — is on the market and for rent.” It’s the only one of five units still available.
