A Santa Fe, N.M., developer hopes to create what may be the first openly gay retirement community, aimed at the special needs and interests of gay men and lesbians. Rainbow Vision Santa Fe closed on a 12.7-acre parcel in the Santa Fe City limits last year and is now preselling and pre-leasing 146 units to be built on the site. These will comprise 40 condominiums (starting at $250,000) and 106 independent and assisted living rental units.
