Answer:
The rent and utility bills
Explanation:
Rent is the biggest recurring cost you have to pay each month if you rent a private house. The rent is usually paid at the beginning of a new month, in some cases in advance for the whole period of rent.
Utility bills that you have to cover include gas, electricity, water, a TV licence, internet, and some community services such as garbage disposal, cleaning of communal areas or gardening for example.
Some of the utility bills can be paid quarterly or even yearly, most of them, however, need to be paid on a monthly basis.
