The pictures aren’t great, but as others have said the video walkthrough shows you’ve outgrown/filled the house.
Since you want to move anyway, now is the time for a huge declutter.
If you want to keep everything, box what isn’t needed now, keep the prettier and most needed things, box the rest, label & stack neatly to one side of the garage.
First picture should be if the house, otherwise many disregard the listing thinking you have a ugly exterior and are hiding it
Floorplan
Clear your hallway.
You’ve got coats hanging in two spaces, and boxes of shoes as well as the shoe bench.
Hang coats go under the stairs and put all shoes you use daily in the bench
Fix and paint your kitchen ceiling, it looks like you had a leak or moved spotlights
Replace/repaint the fridge cupboard door.
Remove all kid stuff and everything from the top of cupboards.
Add flowers, fruit, anything lifestyle-y that doesn’t scream ‘I have 3 kids and have run out of room’.
Upstairs bathroom needs mould removing from ceiling.
Then something to blend the brown aqua panels in, rather than making them the feature.
I’d change the blinds to wood, remove mismatched towels, one laundry basket, squeegees, toys, cleaning products & add plants
Clear the landings.
Box up all the books
Remove the bookshelves to the garage.
The two smaller units look broken anyway.
All this on the small landings says you’ve run out of room elsewhere.
Make the kids beds and try to clear as much as possible in their rooms off the floor and walls. Remind them they can get it back once you’ve moved.
Particularly clear under beds & tops and sides of wardrobes. Bin bag has to go
Clear the stuff off the shelves in master bedroom & at a push add back a couple of items like perfume. You’ve got a Philadelphia pot there ;)
Have a look at some other listings near you, particularly show homes and see how they style them.
Aim for similar.
You want your photos to jump out as clean, beautiful, aspirational living from a picture the size of a matchbox on someone’s phone.
Your home isn’t bad.
It just looks lived in & loved.
And that doesn’t sell quickly.
How you live when selling should be like you are expecting demanding family/royalty to visit.
When we last sold with smaller kids, we hired a storage unit, and every viewing shoved everything that wouldn’t fit in a cupboard somewhere in the car (including the cats beds, drying laundry) whenever we had a viewing, and usually went for a drive. Don’t overfill your fitted wardrobes as viewers do like to open anything that is staying!
