Selling a home can involve significant costs that must be considered before listing with a realtor. These costs include: - Discounts off the asking price (average 3%), real estate commissions (average 5%), and closing costs (2-4% of sale price). - Holding costs like loan payments, utilities, insurance, and yard maintenance over the estimated 4-6 month marketing period. - Additional marketing and repairs costs like appraisals, inspections, and fixing any issues buyers require. - The total cost to sell is the sum of all these expenses plus any mortgage payoffs and the realtor's commission, which determines the net proceeds from the sale.
