I paid 30 dollars for the deposit and pay monthly rent.
What I want to write is "this apartment costs 30 dollar for the deposit, and I pay monthly rent(, which means I don't have lots of money.)"
I know in English we try to keep the tense in the sentence, but here, it's obvious that I paid the deposit in the past, and I still pay monthly rent since the apartment isn't mine.
Is it okay to write like this? I also tried to start the sentence with "the apartment costs...", but I wasn't sure if it's gonna work in English. Or could you tell me a better option?
