I certainly know what the listing agent is trying to achieve with that language: the home represents a rare purchasing opportunity, so Buyers had better hustle or risk missing out (for another 57 years?!?).
In practice, however, my association with the above — and I suspect most Buyers’ as well — is that the home is dated and/or functionally obsolete.
Instead, when I represent such Sellers (and their homes), I focus on showcasing the home’s strengths (vs. trumpeting how long since it was last sold).
“This Fine Home Only Available Due to Relocation”
At the other extreme, of course, are homes that just sold, and are seemingly back on the market the next week.
Trying to deflect Buyer questions about the owner’s short tenure, many listing agents will proactively address that concern by saying in the MLS marketing verbiage that “the home is only available due to relocation” (or some other benign explanation).
Same as above, my instincts are to market the home’s strengths — not emphasize the Seller’s motivation or selling circumstances.
