Earlier quoted context omitted.
In Japan, we have a special term for real estate that has become a financial burden on their owners: "負動産" (fudosan, negative real assets). It's such a huge social problem that people choose not to accept the inheritance if it involves old properties in rural areas.
May i ask, is there also a dedicated term for "positive real asset" in Japanese?
Some seems to use the term "富動産" to mean that, but I don't think it's catching on.
Side note: normal real assets are called "不動産" (which pronounces as "fudosan"; it originates from Immobilière in French) in Japan. It's all about puns.
