Palm Beach Daily News Real estate developer Michael Joseph and his wife, Roberta, have parted with the ultra-contemporary-style house they built for themselves on Ibis Isle’s lakefront in the South End of Palm Beach. The sale price of the two-story house at 2288 Ibis Isle Road W. was reported Tuesday at $10.458 million in the local multiple listing service. The deed was still making its way through the recording process Tuesday, so the buyer’s identity wasn’t yet known. It was also unclear if the price recorded in the MLS will match the one to be documented by the Palm Beach County Clerk’s office.
