What’s the first thing to do when selling your home?

I think it's always good to get an experienced agent in right away.  Sure, you can get rid of the clutter first and organize the closets, but an experienced agent can let you know what else should be done and that way you can budget your time and money.  An agent knows what buyers are looking for and may be able to tell you what improvements (or fixes) will generate the most return but, more importantly, also help you sell for the highest price
