It used to be that mortgages had what's called a balloon payment at the end.

它曾经用于房贷，最终叫做气球付款。

But what they weren't looking at was, okay, there's a balloon payment five years down.

但是，他们没看到的是，在五年后，有最末期大笔还款在等着你。

They often end with a large payment, a balloon payment, which owners usually refinance.

这些贷款在到期时通常是大额还款，即分期付款中最后一笔大额付款，业主往往再融资。
