In the world of "luxury" loft sales, we thought we'd pretty much seen it all when it came to sales incentives. MOCA memberships. Tuna tartare on waffle chips. Free houseboys. Celebrity-cachet. The Lofts @ Hollywood and Vine are going one better. Dispensing with some of the sillier gimmicks, the building is now offering to pay 50% of buyers' HOA fees - FOR THE NEXT FOUR YEARS - if they close before the New Year. Cold, hard cash - almost better than that free houseboy. Almost.
