You have a nice house, but as others have said its a difficult market and you have to be realistic if you want / need to sell.
Is your price sensible ? Obviously its a bit over the stamp duty threshold which puts some off. But its only a couple of thousand in duty, could you offer that you paid that to the potential buyer ? I have seen a number of houses where they are offering to do this.
If you have a dog. Wash him, and wash the room and keep windows open for a few days. Even if you think he doesn't smell. He will.
I have a dog myself
but notice other peoples dogs smell in their homes. I went to view a footballers house the other morning. It looked lovely from the pictures but golly I had to hold my nose when we went into the kitchen !!
Agree with the comment on curtains, blinds open or roll them up to expose the maximum amount of light. And declutter, but i think this is less important in childrens bedrooms. I had a lol at all the remotes on the table !
I would stage your dresser in the kitchen a bit more. Interspace the books with the ornaments on all three shelves.
Put some lovely towels on the towel rail in the bathroom and DO NOT LET ANYONE USE THEM.
What are those ping pong balls on the kitchen table light for ?
Oh and make the conservatory more appealing as a room. Set it out with a table and put a newspaper neatly folded up on it to give the impression that you sit and leisurely read in there and its not the dog space !!
Good luck and let us know how you get on.
