I am due to move house in a few weeks time. The property has had several previous owners and was lately used as an investment property occupied by students. Would it be wise to change the outside door locks as soon as we move in?

This is probably something that very few purchasers actually do as they rely on the integrity of their sellers who themselves will presumably have regarded their own security as paramount.

However, when you think about it you have no idea who may have had access to keys at any time and, while the fact that you are purchasing a former investment property will make this point more obvious, it is technically an issue that should be considered by all buyers.

The answer is, of course, should be that to ensure your security you should always consider changing the locks.
