Hi
Just my opinion. The upstairs is really lovely! It looks modern, fresh and wouldn't need any work to make it somewhere comfy to live while you wait to put your own personality on the place as a new buyer.
But downstairs doesn't meet the same standard. The outside has no kerb appeal, the dated interior downstairs is a let down and some of the work needed would put me off like the stairs.
Upstairs looks lovely but downstairs doesn't match up and the back garden looks small too.
As a buyer, i'd be adding up costs to do the following:
-Replace dated orange tiles on fireplace in front lounge (and wallpaper)
-Make stairs more secure
-Change kitchen tiles and counters
-Make conservatory floor warmer
-Does wood cladding need to be replaced from garden pics?
-Small garden and not attractive
In your shoes, i'd start with kerb appeal. Even some potted plants and flowers to make it more welcoming because the pebble dash is unattractive compared to both neighbouring properties.
Add some warmth to the front lounge like a vase of flowers in the fireplace. That room also looks like it has no purpose. Should it be a dining room? Can you stage it better?
Declutter the main lounge a bit more as you can't really do anything else. Its nice enough as is and you probably don't want to go to the expense of adding a back board to the stairs.
Your kitchen on one hand has nice units but the tiles and counters make it look dated IMO. Could you add white or cream accessories to help neutralise all that brown and orange? Hide the fruit and don't use yellow flowers as these clash.
I'd put a white or cream rug down in the conservatory and stage it better. It looks cold and unused.
Could you declutter the paved section of the garden for another photo and add some bright flowers and potted plants to the grassed section? Maybe repaint the cladding as well?
Good luck with your sale.
