Frustrated by overheated multi-family prices? Here's a rationally priced duplex to cool you down! Seller paid low, enabling him to sell low. Massive 3-bedroom front house + detached cottage behind it. Both units presently rented. $1,450 / mo. total income. Yes, 'the numbers work.' No speculation on this deal. Both structures are in very good shape, and thoroughly imbued with genuine 1930's charm. Yard space abounds, comfortably shaded by a champion Banyan Tree's protective canopy. Timing is everything in the real estate trade, second only to location. Have capital ready? Then lucky you are, this duplex has arrived for sale, right now. Especially fortuitous is its superb location... Lake Worth's highly desirable, scenic, ''Tropical Ridge'' neighborhood.
