Whether you are finding a house to move into straight away or following on from living in halls of residence my only advice would be;
FIND YOUR HOUSE AND PUT YOUR DEPOSIT DOWN EARLY.
As much as it's probably one of the most serious things you may have done in your life, sorting out your housing early is extremely necessary, and I cannot stress this enough, as you do not want the added pressure of finding a house as well as trying to juggle increasingly difficult and time-consuming work.
Furthermore, when leaving finding a house until the last minute you will end up living somewhere unpleasant and where you are unhappy. Fact.
Make your life easy, and at least start viewing houses around christmas, then you have months ahead of you if you need to buy furniture/save up money etc, it just makes your life a lot more simple.
