Some costs are relatively straightforward to check. For example, you can find out what the rateable value of the premises are, and ask for quotes for building insurance.
Ask to see the previous owner's bills for utilities. Estimate whether your own bills are likely to be higher or lower. Check whether there is any service charge and if so how it is calculated.
The most variable costs are usually for maintenance and repair. Your survey (see 12) should provide guidance on this.
