In most cost-vs.-benefit analyses, a dressed-up entry door is the best possible improvement that sellers can make. But don't go too far -- you don't want to hang the high-end, leaded-glass version on the jamb unless you're in an upscale neighborhood.

Like a new entry door, a brand-new garage door also tops the list of improvements that will help your home make an excellent first impression.

A couple of factors work against making a big production of a deck: You won't get anything close to a dollar-for-dollar return, and some buyers might want to do something else with that outdoor space.

This type of deck will return more of your cost while creating a good impression of how life can be lived in your backyard.

Your home's exterior is something the buyers will register before they see anything else about the house. In this case, higher end is better, and it will bring a good return.

No one will fault you for failing to install a $5,000 granite slab for your countertop. You'll get back some of the money you put into an expensive kitchen remodel, but not as much as you'd like.

If you have a very dated kitchen, go ahead and update the cabinets and replace the appliances. But it's OK to choose the more affordable Kenmore oven over the Viking.

By all means, break out some oil and scrub up that wood. But don't pull out the cabinet boxes -- that can be pricey, and you definitely won't get your money back.

This is a relatively inexpensive fix that can draw attention away from that '80s track lighting and give buyers the impression that your home is up to date.

This is an easy, fun addition that helps buyers envision how well their stuff can fit into the space.
