Do you have any more balance sheets to view besides the two?

That's usually not nearly enough to get to know a company

Also, there should be notes about anything this major on the statement

Check around, you probably missed them

Looks pretty simple: they borrowed money to buy investment properties. Their current borrowings probably rolled over into long-term borrowings. Don't put too much emphasis on short-term balance sheet entries.

Former long-term borrowings -> Current borrowings most likely, maybe increased short-term borrowings for increasing working capital. Without looking at the notes I'd be concerned for liquidity issues on the short term.
