Xiaoyu reads her lease through at the agent's before signing. Two points are not in it, and a third depends on the landlady.
The agent
小雨，合同我已经打印出来了，你先看一遍。
Xiǎoyǔ, hétong wǒ yǐjīng dǎyìn chūlái le, nǐ xiān kàn yī biàn.
Xiaoyu, I have printed the contract out, read it through first.
Xiaoyu
好。上面写着租一年，到期可以再租吗？
Hǎo. Shàngmian xiě zhe zū yī nián, dàoqī kěyǐ zài zū ma ?
Right. It says a one-year tenancy. Can I renew when it expires?
The agent
可以。不过房东那个时候可能会涨一点儿房租。
Kěyǐ. Bùguò fángdōng nà gè shíhou kěnéng huì zhǎng yīdiǎnr fángzū.
You can. Though the landlady may put the rent up a little at that point.
Xiaoyu
除了房租以外，我每个月还要交什么？
Chúle fángzū yǐwài, wǒ měi gè yuè hái yào jiāo shénme ?
Apart from the rent, what else do I have to pay each month?
The agent
物业费两百，水和电按你用的算。
Wù yè fèi liǎngbǎi, shuǐ hé diàn àn nǐ yòng de suàn.
Two hundred in management charges, plus water and electricity on what you use.
Xiaoyu
这一条合同里没有。麻烦你把它写上。
Zhè yī tiáo hétong lǐ méiyǒu. Máfan nǐ bǎ tā xiě shàng.
That clause is not in the contract. Could you add it in, please.
The agent
没问题，我现在就把它加进去。
Méi wèntí, wǒ xiànzài jiù bǎ tā jiā jìnqù.
No problem, I will put it in right now.
Xiaoyu
押金是两个月。搬走的时候怎么退？
Yājīn shì liǎng gè yuè. Bānzǒu de shíhou zěnme tuì ?
The deposit is two months. How is it returned when I move out?
The agent
房子没被弄坏，押金全部退给你。
Fángzi méi bèi nònghuài, yājīn quánbù tuì gěi nǐ.
If the flat has not been damaged, the deposit is returned in full.
Xiaoyu
空调要是自己坏了呢？
Kōngtiáo yàoshi zìjǐ huài le ne ?
And if the air conditioning breaks down on its own?
The agent
不是你弄坏的，房东负责修。
Bùshì nǐ nònghuài de, fángdōng fùzé xiū.
If you did not break it, the landlady is responsible for the repair.
Xiaoyu
那还有一件事：我想养一只猫。她一同意，我就签。
Nà háiyǒu yī jiàn shì : wǒ xiǎng yǎng yī zhī māo. Tā yī tóngyì, wǒ jiù qiān.
Then there is one more thing: I would like to keep a cat. The moment she agrees, I sign.
把它写上, 把它加进去: the object moves ahead of the verb, and the verb takes charge of what is being done to it. It is the Chinese construction for saying you ACT on an object already known, and it always requires a completed verb: neither 把它写 nor 把它加 can stand alone. There has to be a 上, a 进去, a 了, something that says where the thing ends up.
除了房租以外 means "apart from the rent" here, and what follows adds to it (还要交什么). The same mould also serves to exclude, and it is the 都 or the 只 in the second half that decides: 除了房租以外都交了 means everything is paid except the rent. Without a 还 or a 都, the sentence stays ambiguous for a Chinese speaker too.
押金 is the deposit, usually two months, returned when you leave if nothing is damaged. 物业费 are the management charges, paid to the management company and not to the landlord: they cover the lift, the caretaker and the cleaning. They are almost never inside the advertised rent, and they are the first thing to ask about.
