Paid upfront, shouldn't have. House been on the market for 7 months. Only 3 viewings, more booked but mysteriously cancelled and a rediculous offer almost seems it was just to get their stats better. Paid an extra £300 as advised for them to do viewinga, but have ended up doing 50%of them myself! Being an ex London estate agent I took the punt thinking I just need to get it on rightmove. And the viewings will flow. If you don't live in London don't use YOPA. get a local estate agent that can show your property to people even if they didn't request to see it.
