صاحبخانه گفت که اگر اجاره را به موقع پرداخت کنیم، خوشحال میشود.

صاحبخانه means landlord or landlady—literally something like owner of the house. In everyday Persian, it is commonly used for the person who owns the place you rent.

You may also see it written as صاحب‌خانه with a half-space. Both refer to the same word.

که often means that and introduces a clause after verbs like said, knew, thought, and so on.

So:

• گفت = said
• گفت که ... = said that ...

In Persian, که is very common in this kind of sentence, much like that in English.

را marks a specific direct object.

Here, اجاره را means the rent as the thing being paid.

So:

• اجاره = rent
• اجاره را = the rent (as the object of the verb)

In Persian, when the direct object is definite or specific, را is usually used.

به موقع means on time, punctually, or at the proper time.

So:

• اجاره را به موقع پرداخت کنیم = we pay the rent on time

It is a very common expression in Persian.

After اگر in this kind of future or uncertain condition, Persian often uses the subjunctive form.

So:

• پرداخت کنیم = that we pay / if we pay

Here it expresses a condition: if we pay the rent on time.

The form is built from:

• پرداخت = pay (verb base used here)
• کنیم = we do

Together, پرداخت کنیم functions as we pay in this conditional structure.

In Persian, verbs usually show the subject through their endings, so subject pronouns are often omitted.

For کنیم:

• -یم marks we

So پرداخت کنیم already means we pay, and there is no need to add ما unless you want emphasis.

The subject is understood to be صاحبخانه.

So the sentence means that the landlord will be happy.

Persian often leaves out repeated subjects when they are clear from context. After mentioning صاحبخانه at the beginning, the sentence does not need to repeat او (he/she).

Literally, خوشحال می‌شود is something like becomes happy or gets happy.

But in this sentence, because it follows an if clause, English usually translates it more naturally as will be happy:

• اگر ... پرداخت کنیم، خوشحال میشود
  = If we pay ..., he/she will be happy

So the Persian present form often corresponds to a future meaning in English, especially in conditional sentences.

Yes. They are the same word.

• می‌شود is the more standard spelling, with a half-space.
• میشود is a common simplified spelling in informal typing.

Both are read the same way and mean the same thing here.

A rough breakdown is:

• صاحبخانه گفت = the landlord said
• که = that
• اگر = if
• اجاره را = the rent
• به موقع = on time
• پرداخت کنیم = we pay
• خوشحال میشود = he/she will be happy

Persian typically puts the verb at the end of the clause, so learners often notice that the sentence structure feels more verb-final than English.

Persian often does not need a separate future marker in everyday speech when the meaning is already clear from context.

In conditional sentences like this one, the present form can naturally express future meaning:

• اگر ... پرداخت کنیم، خوشحال میشود
  = If we pay ..., he/she will be happy

Although Persian does have a future construction, everyday Persian very often uses present forms instead.

A common transliteration would be:

sâheb-khâne goft ke agar ejâre râ be moghe' pardâkht konim, khoshhâl mishe.

A few pronunciation notes:

• صاحبخانه: the kh is like the sound in German Bach or Scottish loch
• را is often pronounced ro in everyday speech, even though it is written râ
• می‌شود / میشود is often pronounced more like mishe in conversation

اجاره most commonly means rent or rental. Depending on context, it can refer to:

• the rent payment
• renting something
• a lease/rental arrangement

In this sentence, because it is something being paid, it clearly means the rent.

Yes.

This version is already quite natural. But you might see small differences:

More standard writing:

• صاحب‌خانه گفت که اگر اجاره را به موقع پرداخت کنیم، خوشحال می‌شود.

More conversational speech:

• صاحبخونه گفت اگه اجاره رو به موقع بدیم، خوشحال می‌شه.

In the conversational version:

• صاحبخانه → صاحبخونه
• اگر → اگه
• را → رو
• پرداخت کنیم → بدیم (give/pay in a more everyday way)
• می‌شود → می‌شه

So the original sentence is grammatically good and fairly neutral, but spoken Persian often sounds simpler and more relaxed.
