Like many people in the UK, I've recently registered to use a fantastic service which makes Land Registry house prices available. The service is provided by NetHousePrices and, essentially, it allows you to type in the name of a post code or street and find out what price people paid for properties that match the search criteria. The most recent update from the site is that the service will now be provided free for the foreseeable future which is a major boon. So, if you want to find out what a house last sold for check out the site. I could actually see this kind of site having a real effect on house prices. For example - if you turn up to view Number 7, Acacia Avenue and it's for sale for £350,000 you might feel a little squeamish about paying that if you can do a quick search and find out that it was bought for, say, £180,000 about 4 years ago. I know, I'm a dreamer...
