Start with your minimum and preferred price. Most estate agents often come up with a similar figure.

• Do some research locally. Find out what similar properties have sold for in your area. Ideally, ask a neighbour who has recently bought or sold.
• Search for similar properties on the Internet to get guide prices.
• Talk to your neighbours - they may have recently changed their mortgage provider and will have had a valuation carried out.
• If you are still not sure, ask an estate agent - they will be happy to give you their opinion (and try to sell you their service).
