Questions & Answers about yachin o harau kouza o kaetai node, ginkou ni ikimasu.

Why are there two を particles in this sentence?

Because they mark two different verbs:

• 家賃を払う = to pay rent
• 口座を変えたい = want to change the account

So the structure is:

• 家賃を払う modifies 口座
• then 口座を変えたい is the main idea before ので

In other words, the sentence contains a smaller verb phrase inside a bigger one:

• [家賃を払う] 口座 = the account used to pay rent
• その口座を変えたい = I want to change that account

So each を belongs to a different verb.

How does 家賃を払う口座 work? Is it a full clause?

Yes. This is a very common Japanese pattern where a plain-form verb phrase directly modifies a noun.

• 家賃を払う = pay rent
• 口座 = account

Together:

• 家賃を払う口座 = the account from which I pay rent / the account used to pay rent

Japanese does not need words like that, which, or used to here. The verb phrase comes before the noun and modifies it directly.

Other examples of the same pattern:

• 日本語を勉強する学生 = a student who studies Japanese
• 昨日買った本 = the book I bought yesterday
• よく行く店 = the store I often go to

So 家賃を払う口座 is very natural Japanese.

Why is it 変えたい and not just ?
