I always find it is a good idea to keep up to date with property news both good and bad. Here are some useful links for you to browse which I will add to as and when I remember
Daily newspapers Althought they mean well they are in the business of selling newspapers and not necessarily the truth http://www.rics.org/ Royal institute of Chartered Surveyors
http://www.property-tax-portal.co.uk Very good site for property tax information. Property Portfolio Software provides solutions to help self managing landlords get better organised when managing multiple properties.
