I must admit, I want to see a house 'presented' as a viewer.
When we sold, we had a major declutter and stuck all the boxes in the attic. We also never had the following on show:
Hoover, dustbin, ironing board, iron, ironing basket, toiletries, coats, shoes, bags, mop and bucket, washing powder etc
This usually involved shoving all the coats/shoes into the boot of the car before a viewing and taking the larger things (like the bin) into the garage. The garage was rammed but viewers only asked to see it on a second viewing and of course, they didn't mind it being rammed as it was obvious we were moving.
The other thing was, I always removed all the towels and toiletries in the bathrooms and replaced them with new (white) towels and nice toiletries I kept in a 'viewings box'. It was a pain in the neck at first but I became very adept at setting the house up and we sold to the second couple who viewed (total of five or six viewings) for almost the asking price.
If you're serious about selling and want a good price, I'd recommend going to town on presenting the house. Deffo no cardboard boxes on show!
