In the following scenario you can buy/sell offices in different cities, so say the user purchases an office in London, then the user sells it and we wish to show the user a message that the sale has taken place, should it be phrased like:
this,
You sold your Office which is situated in London for 495,000.
or
You sold your Office which was situated in London for 495,000.
It is generally phrased as something like: "Your London office (or office in London) has just sold for $495,000". This is because of aspect in reference to past tense.
Both the versions are possible, however with different focusses. The first one looks at the office as still existing. The second one as admitting of no link of the office to speaker's present.
