500 is more than enough for such small apartment, so don't worry you can find nice one within the budget ...and no you dont have to pay 1 year in advance ...most common rent in Jordan is monthly or every 3 months
Also for you Gina you can place your offer in the appropriate place which is the housing section in the green banner above the page.
I must say that your electricity and water bills are more expensive then what I have to pay for. For a family of five I pay electricity around 15 dinar (in the winter a bit more) a month and water 4.5 dinar for three months.
If the water bill is up to 30JD for such an apartment and one person then there is definitely something wrong unless you have a swimming pool and fill it every day. When I used to live in the capital it was less than 6JD every three months. Consumption normal like every day showers, washing machine, kitchen stuff etc... Now I pay up to 25 and am shocked. I was told its because of one water hour for 5 Apartments. They just split the costs put the consumption has not become more and I was not happy with this. Next time I will definitely rent only with own water hour cos this is redicilous. I paid electricity up to 4 JD, now between 6 and 8 for two people.
Just i want to add, it depends on Consumption, whether big family or single person, but what ghina mentioned is very high costs for a normal flat. She should, as Primadonna said:
