A student is (informally) introducing himself:

> 先週からこのシェアハウスにやってきた大学3年生。

IIUC, やってきた (just like 来た) is an instantaneous verb, i.e., it expresses an
instantaneous change from one state to another. On the other hand, I thought
`<time>+から+<verb>` can only be used to describe something happening over a
period of time.

So I expected that the above sentence is incorrect, and must be rewritten as:

> 先週このシェアハウスにやってきた大学3年生。 (drop から)

or

> 先週からこのシェアハウスに泊まっている大学3年生。 (use a stative verb)

However, the original sentence is from a Japanese textbook, so I'm sure it's
correct. What am I misunderstanding?

question
grammar
Can <time>+から be used with an instantaneous verb?
Your understanding is correct. から marks the beginning of a period and should
not be used with an instantaneous verb like （やって）くる. I would say that sentence
is grammatically incorrect.

Having said that, though, a sentence like that is not uncommon in everyday
conversation. The meaning of いる is inferred from やってきた and いる is compatible
with から.
