Within six months last year, Carlos and Betti Lidsky bought and sold two condominiums. Then they bought and sold two houses. They say they will clear a half-million dollars in profit, and none of the homes have even been built.Now Mr. Lidsky, a lawyer, and his wife, a charity fund-raiser, have put down a deposit on a fifth property, a $1.3 million condo in a high-rise under construction, and are planning to sell before the deal closes, without even taking out a mortgage.
"It is much better than the stock market," Mr. Lidsky said. "This is an extraordinary, phenomenally good result."
