The aroma will make the buyers feel welcome. If you're present when the house is shown, do not apologize for the appearance of your house. After all, it's being lived in. Let the agent answer any objection - it's part of the job. Have ready your receipts for electricity, water and gas usage for the past 12 months.
Silence is golden.
Let the real estate agent discuss price, terms and other factors with the buyers. The agent is qualified to conduct negotiations that lead to a favorable outcome for both parties. A little money goes a long way. Your cooperation in making cosmetic repairs increases everyone's interest level and enthusiasm and will help you close the sale.
