Whether you go no-name or brand, I think one of the things that sells a house is staging.
People will always find negatives for your home, whether it be location (close to a main road, freeway... or cemetery), lack of 3CWG, small lot, school district etc so you want to give them less things to QQ about.
A properly staged (and decluttered/depersonalized) home will have an impact on a buyer just like the new homes do. And "decluttered" doesn't mean remove all the furniture and just have clean empty rooms, model homes don't do that. People like to see what a space can be used for.
For example, when we sold our 4-br home, the downstairs room was an office. Our stagers (paid for by IrvineRealtor) made it into a bedroom to show that it was a 4-br home and that it could be used as the infamous FCB-in-law suite.
So whichever route you go, unless you live the Pottery Barn/Renovation Hardware lifestyle, make sure you stage your home.
