Positives:
Bathroom
Kitchen
Bedrooms
Negatives:
The outside with the pebble-dash/render looks awful and jars with the house next door. I know you can't do anything about it, but it will put people off as they will wonder what it is hiding.
Brown Windows against the pebble dash/render I'm guessing they are UPVC so you can't do anything about them either, but they do make the place look dull.
Could you get some colour at the front of the house? Plants in pots, some of those long planters along the front wall? Anything to make it not look so bleak.
Decide which of the two rooms is the living/TV watching area and stage accordingly.
Stage the other as an eating area/study area/play area.
Get a nice rug on the floor of the conservatory and stage it as something - place to sit in comfy chairs, listen to music, play, eat - make it look like an area you use not just a strange dumping ground. It looks cold and uninviting.
Outside - sort out the peeling paint on that white wooden wall. Re-arrange the rabbit hutches and outside furniture it looks a bit muddled and squashed and not a place someone would want to sit outside. Can you store whatever is under the tarpaulin somewhere else? It would free up some space.
The garden area is a mess, why oh why have you got photos like that? The cardboard abandoned by the bin, the bins all over the place? What is that at the end of the garden beside the gate? It looks odd. Try and clean the walls with green mould on them, cut the grass and get some pots with flowers in. Have new photos without the bins, wheelbarrow and rubbish on show.
