Although it is sometimes claimed that no Sears kit homes were built after 1940, Sears continued to offer pre-cut kit homes through 1941 and 1942. Many of these homes were based on models from the 1940 and earlier Sears catalogs but not all were, leading to debate over whether these homes qualify as ``Sears Catalog Homes''. Because these homes were constructed using pre-cut lumber and plans provided by Sears, these homes are considered to also be ``Sears Catalog Homes''. Many of these homes were built in Sears planned ``Home Club Plan'' developments in New Jersey, New York and Ohio. Homes were also built for industrial firms like Bethlehem Steel which purchased and constructed 61 Sears homes in Hellertown, Pennsylvania.

Longer hitters have also accomplished this feat on longer holes, though nearly all par 4 and par 5 holes are too long for golfers to reach in a single shot. While well known outside of golf and often requiring a well hit shot and significant power, holes in one are considered to also contain an element of luck. As such, they are more common and considered less impressive than other hole accomplishments such as completing a par 5 in two shots (an albatross). As of October 2008, a condor (four under par) hole-in-one on a par 5 hole had been recorded on four occasions, aided by thin air at high altitude, or by cutting the corner on a doglegged or horseshoe-shaped hole.
