One of the most common questions asked by people selling without an agent is “How do I value my property?” Start with your minimum and preferred price. Ironically, an estate agent often comes up with a similar figure.
The Land Registry and many free sites give you the selling price of similar properties in your street that have sold recently. Try www.houseprices.co.uk.
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.
Talk to your neighbours – they may have recently changed their mortgage provider and will have had a valuation carried out.
Ask an estate agent they will be happy to give you their opinion (and try to sell you their service).
