I wouldn't know where to start

The process of selling a house doesn't have to be complicated and by cutting out the estate agent you could even speed things up and avoid misunderstandings as you can negotiate directly with your buyer without going through a third party. In a nutshell, here's what to do:-

1. Register with Behoused, upload your property details and pay your one-off fee
2. When someone is interested in your property they will contact you directly
3. Arrange and conduct your own viewings and negotiate a price and included fixtures and fittings directly with the buyer
4. Once a sale is agreed, exchange solicitor/conveyancer details with your buyer
5. Your solicitor should handle the rest of the process and will confirm to you when you have been paid for your property and when you have to hand over the keys and vacate
6. If you are buying another property, your solicitor or conveyancer will integrate the purchase so the whole process runs smoothly

Negotiating a price is probably the point that will concern most private sellers so it's important that you have in your mind the price you are prepared to accept and you stick to it.
