You are asking the right questions and that makes you smarter than a lot of the home owners out there right now. As a buyer, it comes down to what do I have to do to that house to (a) make it liveable and (b) go with my stuff. If you have blood red or neon orange walls, paint them a soft neutral color. It will make the house look and feel expensive, brighter and bigger. (Light colors expand a room while dark colors visually shrink any space.) Then, I won't have the added expense of having to paint that orange and purple striped room that will clash with my black leather couch. Move big pieces of furniture away from windows. You want to seller to walk up and look out the window. It's inviting and makes the seller feel like they are home. Position a minimal amount of furniture in each room because that makes them appear expansive. Store the rest of it and pack away any clutter on shelves, bookcases, your collection of 1000 CD's, etc. I can visually any room as empty with white walls and picture my furniture there. On the other hand, carnation pink jetted tubs, red sinks, plaid carpets and purple walls will send my husband rushing out of the house. The poor guy can't visuallize the house as ours which is why we haven't purchased yet.
The other issue is price. With all of the tools out there, buyers can easily find out that Albuquerque home prices have dropped 17% in the last 12 months. Don't make your house the highest price per square foot in your neighborhood. Honestly, if I had to sell in today's market, I would make my house neutral, turn-key ready and price it 5% below the lowest price per square foot house in the area. (Ignore the ones that are a wreck).
