If you're considering selling, the estimated sales price of your home would depend on a large number of factors - the neighborhood, condition, sq ft, number of bedrooms, number of bathrooms, size of the garage, etc.

I (or any other Realtor) could provide you with a free, Comparative Market Analysis (CMA). A CMA is an estimate of your house's value to suggest a selling price. It would compare your home with comparable properties in the area including properties that have sold and closed within the last 12 months, active listings, pending sales and expired sales. Please note that a CMA is not an appraisal.
