When your real estate agent comes to your home to perform the CMA, look at the meeting as an opportunity to explore the questions you have.  Share what you’re trying to get out of your renovation plans and ask him or her what they think. Be sure to ask your agent to, what value they think your renovation will add to your apartment’s value. It may surprise you to learn that while some renovations, like a new bath or kitchen add substantial value, others, like adding or subtracting walls may not and may even lower value of your current residence. Thinking of adding a three hundred bottle wine cave? An alcoholic buyer may see that as the first thing he needs to remove. You get the picture.
