How to price your home correctly?
For this, you should enlist the help of a reputable listing agent. Don't choose your cousin's sister-in-law, for example, who dabbles in real estate. You'll fare much better if you select an experienced real estate agent who sells a fair number of listings, preferably in your neighborhood.
Your agent will analyze comparable sales and prepare an estimate of value often called a CMA, for comparative market analysis. It is OK to compare the Zestimate at Zillow but note the variances your agent will point out because your listing agent should have the experience and education to provide you with a more accurate opinion of value.
