Check what the deposit covers , make sure any damage/faults already existing are noted down so you don't get stung for them at the end of your lease .
If you decide to have a big party in advance , as opposed to just having a big party happen , remove or cover the carpets and take out all the furniture .
Check the utility meters (if the house is metered ) some landlords heavily fix them , alternatively wire the house to the nearest street light .
