I am a native English speaker, and "properties" as "pieces of real estate" is common in my experience. "Properties" to refer to characteristics sounds more like scientific use to me, and not used in reference to personal characteristics. In other words, I doubt someone would say "I have two properties" to mean, for example, "I am tall and stubborn."
You could use "two properties" in English to describe inanimate objects. "The two beneficial properties of this fabric are its durability and its flame-resistance." So, yes properties is a synonym for characteristics in English. However, Soglio is right that it would be odd to use the word "properties" to describe characteristics of a person.
