In an unofficial vote, residents of a condominium complex have supported selling their homes to Seattle-based Children's Hospital and Regional Medical Center. The board of the 136-unit Laurelon Terrace condominiums have presented Children's with a tentative deal to sell the six-acre complex to the hospital for $93 million. Children's Hospital has been buying individual units with an eye toward using the site for future expansion, but the new deal would let the hospital expand onto the site sooner.
