As John stated, people expect a closet in a bedroom. Regardless of whether or not one is technically required for it to be considered a bedroom, you ought to put one in nonetheless. This is a huge plus for a room and something that can be very inexpensive to add. When potential buyers go into a room without a closet, they tend to think, "What is this room supposed to be?" You don't want to do renovations and skip out on this important step! Another 'plus' you may want to consider is the actual design of your closet-to-be. Think about what sort of problems you may have had with closets you've had in the past. Either there was a lot of wasted space on the top of closet, too much hanging space with a lack of any shelving, etc. Consider designing your closet to be efficient for the people of the 21st century who tend to have lots of clothes and in a woman's case, LOTS OF SHOES AND HANDBAGS! Just remember to keep your materials of good quality, but not to 'overspend' on these upgrades as you want to be sure you get back a minimum of 100% return on your investment. Good luck!
