Colorado’s McGinniss GMAC Real Estate has a listing for Robert A. Heinlein’s Colorado Springs home. The four-bedroom, four-bath, 4400-square foot home in Broadmoor is currently listed at $650,000. And the provenance of the home may be a selling point: realtor Sharon Roland writes “Superb Location!!! Historic home built by noted science fiction author Robert Heinlein sits on a quiet 1.5 acre lot within walking distance of the Broadmoor Hotel & Cheyenne Canon. Main level with parquet wood flooring throughout features a large formal living room w/moss rock fireplace and walnut wainscoting, spacious dining room, galley kitchen with breakfast nook and walkout to 10×35 patio overlooking the private wooded lot w/three cascading ponds!”
Heinlein and his second wife, Virginia (known as Ginny) moved from California to Colorado in the late 1940s, and built their own home in 1950-51. They left for lower altitudes in 1965, for her health. In 1952, Popular Mechanics featured the house (and the Heinleins) in an article, which is available at this link. The article notes that the house’s third owner, who bought it in 1995, substantially rebuilt and expanded it, leaving little of Heinlein’s original design.
