This is a UK specific real estate English term on a German tld. Some English words with de extensions have historically shown good aftermarket sales.
The exact search stats for this term are in the mid xxxxx's and show a downward trend. The non exact searches which include this term are in the low xxxxxxx and show an increase after a slight decline in the past several months.
As this is a commercial single word domain, the value is good, but the mismatch in language and geo extension reduces the quality significantly. For the right buyer mid to high $xxxx is fair.
