Deciphering Realtor-Speak
To non-Realtors, “immaculate” suggests an updated home in mint condition.
In real estate sales, however, “immaculate” simply means that the home is exceptionally clean and everything is in working order.
So, the mechanical’s may all be functional, but they’re ancient; the Kitchen and Bath’s date to the 1950’s (or earlier); there’s no Master Bath, etc.
Sure enough, the listing cited above includes this language at the end of the “Agent Remarks” section (where the Realtor extols the home’s virtues): “move in or remodel.”
P.S.: Terms such as “long-time owner,” “much-loved home,” etc. have the same connotation.
