Below is a housing guide for students going to London.
University accommodation (住所) offices
     Many university accommodation offices have their own list of registered landlords (房东). Others also
provide information on accommodation agencies and other housing organization. The advantage of using
your university accommodation is that you can get support if you have a problem. The disadvantage is that
they are unlikely to have enough registered landlords to house all their students.
Property papers: Loot and Renting
     Loot is an important source (来源) of information about private housing for co-renters. The offers are
from private landlords, agencies and individuals looking for other co-renters. They also have a website:
www.loot.com. The advantage of using Loot is that there are some excellent bargains. The disadvantage
is that there is no quality control over the offers.
Renting is another useful paper. The offers in this paper are mainly from accommodation agencies. Their
website is at www.renting.co.uk.
Accommodation agencies
     The majority of rented accommodation in London is probably advertised through accommodation
agencies. The advantage of using accommodation agencies is that you will have access to a large number
of accommodations. A good agent will listen to your requirements and can save you time in looking for the
right accommodation. The disadvantage is that they will make a range of charges to potential renters.
Noticeboards
     Around the universities you will find a number of noticeboards where offers of accommodation will
be posted. These will either be from landlords or from students. Some universities will also have online
noticeboards where students can advertise to other students. Advertisements from students can be an
excellent way to find accommodation. However, advertisements from landlords can be problematic.
Word of mouth
     Some of the best housing in London is never advertised but is passed on from one group of students
to another by word of mouth. It might be that you can find out about good offers from final year students.
However, don’t suppose that just because you have found out about housing from a friend it is necessarily
going to be better than that found through any other source.
Family
     Faced with the very high rents charged in London, some students and their parents will consider
buying as an alternative. In some cases this might be a good choice.
