に marks the target of the contact.

So 不動産屋に連絡して means contacted the real estate agent/agency.

With 連絡する, the person or place you contact is often marked with に:

• 友だちに連絡する = contact a friend
• 会社に連絡する = contact the company

You may also sometimes see へ in similar situations, but に is very common here.

不動産屋 literally means something like real estate place / real estate agent / realtor’s office.

A few nuance points:

• 不動産 = real estate
• 屋 often refers to a shop, business, or people in that line of work

So 不動産屋 can refer to:

• the real estate agency
• the real estate office
• the agent(s) there

It is a normal everyday word, but a bit less formal than things like:

• 不動産会社 = real estate company
• 不動産業者 = real estate business/operator

In conversation, 不動産屋 is very common.

連絡して is the て-form of 連絡する.

Here it connects two actions:

1. 不動産屋に連絡して = contacted the real estate agent
2. 内見の時間を早めてもらった = got them to move the viewing time earlier

So the sentence means the speaker first contacted them, and as a result got the time changed.

The て-form often works like:

• and
• after doing
• by doing

In this sentence, it is basically contacted them and then got the viewing time moved earlier.

内見 means an interior viewing of a property—basically going to see the inside of an apartment, house, etc.

It is a very common real-estate word.

Related words:

• 内見する = to view a property
• 物件を見る = to look at a property
• 見学 = inspection/tour/visit in a broader sense

Compared with 見学, 内見 is much more specifically associated with real estate.

内見の時間 means the time for the viewing or the viewing time.

Here, の links the nouns:

• 内見 = viewing
• 時間 = time

So this is a standard noun-modifying pattern:

• 会議の時間 = the meeting time
• 出発の時間 = departure time
• 内見の時間 = viewing time

It does not mean the time belonging to the viewing in some deep possessive sense; の is just connecting the two nouns naturally.

Because 時間 is the thing being changed.

The verb here is 早める, which means to make earlier / to move up / to advance something. The object of that verb is marked by を:

• 時間を早める = move the time earlier
• 開始日を早める = move the start date earlier

So in 内見の時間を早めて, the speaker is talking about making the viewing time earlier.

Yes. 早めて comes from 早める, which is a transitive verb meaning:

• to move something earlier
• to advance something
• to make something earlier

So:

• 時間を早める = move the time earlier

By contrast, 早くする can also mean make it earlier/faster, but 早める is especially common when adjusting schedules or times.

Examples:

• 出発時間を早める = move the departure time earlier
• 予約を早める = move the reservation to an earlier time

So 早めて is a very natural choice here.

This is a very important grammar point.

Vて + もらう means to receive the favor of someone doing something for you.

So:

• 早めてもらった = I had someone move it earlier for me / someone moved it earlier for me

In this sentence, the someone is the 不動産屋.

So the structure is:

• 不動産屋に連絡して、内見の時間を早めてもらった。
• Contacted the real estate agent, and got them to move the viewing time earlier.

This pattern emphasizes that the speaker benefited from the other person’s action.

The real estate agent did.

That is what 早めてもらった tells you. The speaker received that action from the agent.

So the implied flow is:

1. The speaker contacted the real estate agent.
2. The agent changed the viewing time to an earlier one.
3. The speaker is describing that as something done for them.

If the speaker themselves changed it, the sentence would be different.

Both 〜てもらう and 〜てくれる can describe someone doing something beneficial, but the viewpoint is different.

• 〜てくれる focuses on the giver doing something for the speaker
• 〜てもらう focuses on the speaker receiving that favor

Here, 早めてもらった presents it from the speaker’s side: I got them to move it earlier.

A rough comparison:

• 不動産屋が時間を早めてくれた
  = The real estate agent moved the time earlier for me.

• 不動産屋に時間を早めてもらった
  = I got the real estate agent to move the time earlier for me.

Both can work, but てもらった fits especially well when the speaker requested it.

Usually, yes.

〜てもらう often suggests that the speaker requested, arranged, or caused someone to do something for them.

So this sentence strongly suggests:

• the speaker contacted the real estate agent
• asked about changing the appointment
• the agent agreed and moved it earlier

It does not just mean the agent randomly changed it on their own.

Because Japanese often omits subjects when they are clear from context.

In English, you would usually need something like:

• I contacted the real estate agent...
• They moved the viewing time earlier...

In Japanese, those can be left out if the listener can understand them from context.

So here, the omitted roles are roughly:

• I contacted the real estate agent
• the real estate agent moved the time earlier for me

This kind of omission is extremely normal in Japanese.

The て-form itself does not show tense the way a final verb does. The tense of the whole sentence is determined by the final verb, which here is もらった.

So:

• 連絡して = contacting / after contacting
• もらった = received the favor (past)

Together, the whole sentence is understood as past:

• contacted the real estate agent and got the viewing time moved earlier

This is very common in Japanese: earlier actions in a chain often appear in て-form, and the final verb carries the tense.

Yes, it is very natural.

It sounds like everyday spoken or written Japanese describing a practical real-life situation.

A more polite version might be something like:

• 不動産屋に連絡して、内見の時間を早めてもらいました。

That is the same sentence with ました style politeness.

So the original sentence is natural and casual/plain, while もらいました makes it polite.
