If you think about how this phrase was spoken, with its many "or" phrases, it would clearly have been humorous. That humor is emphasized by the use of the funny word translated as "hundredfold" or "hundred times" that is actually means "getting many times much more." Again, a typical exaggeration used in Jesus's humor.
The last words translated as "eternal life" more literally mean "a perpetual living" or "a life lasting for an age" or "life-long living." The sense of the word "life" as a "living" is emphasized by the word "property" at the end of the verse. The word translated as "eternal" means "lasting for an lifetime" or "lasting for an age." It didn't have the "eternal" sense in ancient times because nothing was thought to be eternal. That is a more modern, Christian concept.
This word for "life" here that can also mean "a living" has a verb form meaning "to live" and "to be alive." It is one of two different Greek terms translated as "life" in the Gospels. This is physical life and the substance of life. It is physical life animated by spirit (see this article on related Greek terms). This is the life that comes from our "substance,” "property," as well as our "existence.” When we talk about making a living, we are talking about this type of life. In verb form, it is a metaphor for "to be full of life," "to be strong," and "to be fresh.” The basic concept is the union of flesh with spirit, to create a breathing body.
