Thomas House, a 205-unit apartment building on Thomas Circle NW that has been operated in recent years as a retirement home, is up for sale.

The Baptist Home of D.C. Inc., the owner, hasn't set a price for the high-rise at 1330 Massachusetts Ave. NW, but it could be a $10 million transaction, based on prices being paid for other downtown apartment buildings with potential for condominium conversion.

The Baptist group plans to consolidate its retirement and nursing home facilities at 3700 Nebraska Ave. NW, where a smaller residence and nursing home are operated. That site has space for a building large enough to take care of the 116 retirement units at Thomas House, a spokesman said. Staff members and tenants occupy 50 units of the high-rise and 39 units are vacant.

The group wants to sell Thomas House but lease it from the new owner until the structure can built at Ward Circle.

Residents of Thomas House, who were notified recently of the plan to sell and rebuild, paid accommodation fees ranging from $11,025 to $28,350 to move in and monthly fees of $435 to $485 for services that include dinner, some nursing care and other services provided in the Baptist program. A rental-only program for senior persons is available, with no accommodation fee, at rates ranging from $655 to $12,052. Non-Baptists may live in the building, which has not been fully occupied over the years.

Many of the residents are long-time Washingtonians, some of whom have already told the board that they don't want to leave downtown to move to Ward Circle.

Thomas House, which now has a 50-bed intermediate-care nursing unit, was purchased by the Baptist group in 1976 for $3.7 million from Pollin Development Co.
