@Isittimenow sure. I read loads and loads on the internet and Pinterest about it, and it really does work! There's a poster on this thread called @Handsoffstrikesagain who does staging for a living who also gave me some really good tips and introduced me to the picture site Desenio. I spent £300 on framed prints as my walls were so so bare, and now they look stylish, and I can take the pictures with me to the new place.
Depersonalise your house by taking down any personal pictures, and replace with the neutral framed prints mentioned before.
I ruthlessly decluttered the whole house, so that anything which didn't belong on a particular surface was binned or went to the charity shop.
In the front room, my bookshelf only has books on, and my shelves now have candles, stylish vases and indoor plants spaced evenly out, instead of junk from all over the place.
I staged the dining room with pictures, a reading corner complete with statement armchair, 2 feature cushions, a throw and lamp. For the professional pictures I also put plates and wine glasses on the table to "sell the lifestyle".
I got a new bookcase for the DC's room (IKEA £50) and cleared out all the toys for the pictures and the viewings. Luckily my parents live nearby, so anything we couldn't fit in the house went to them for "temporary" storage.
In the bedrooms I bought some extra cushions (inserts from IKEA are £10 each) plus covers to set on the beds, plus some cheap throws to put at the end of the beds.
In the bathroom I cleared everything away (shower gels, toothpaste, sponges, shampoo etc) and then cleaned it until it sparkled, as no-one wants to think about using someone else's bathroom.
Two weeks beforehand, I threw some seeds on the garden to plump up the grass and look more green. I also bought a rattan garden set from Wayfair for £130 so people could imagine themselves sitting out there having a drink.
Every mirror, window and glass surface I cleaned with Windowlene to make them shine.
Come back and let us know how it goes!
