Thank you for your question. From a lising agent's perspective my ideal seller/client is the owner of the property that will communicate without being hostile due to the market conditions. Take the information provided to them by the listing agent regarding the price and condition of the homes currently on the market with similar amenities such as location, bedrooms, baths, condition and lot size ect. competing with seller's property as well as what is currently under contract and sold within the last 4 months objectively. Understand that the prices of those home determines the pricing of the home going on the market.
When the property is on the market, make the home accessible, if agents can not get into to show the home, there are so many homes currently on the market agents will just pass up showing a home that is difficult to show.
Have the home ready at all times to be shown, clean, neat, landscaped and lighted. if the listing agent makes recommendation as to what would help, take the advice and get it done, like painting or removing some furniture.
When your listing agent presents an offer, do not get upset. Hear your agent out then give your concerns. Your agent should listent to you also. The buyer should be qualified and your agent should make sure of it. Lots of times the initial offer is a starting point to open negotiations. Negotiate wth the buyer through your agent. Don't just say no or no counter.
When you have a contract you agreed to, follow through, keep your end of the contract. If you signed the contract stating you were going to take care of things, do it in a timely fashion and have the home ready for the closing on the date you agreed upon. When a seller does not line up movers or make arrangements for the buyer to get into the property in time for the closing, that is frustrating to the buyer which trickles down to the listing agent.
Above all, keep in mind, not all agents are the same. There are good honest hard working real estate agents out there doing great jobs, wokring long hours, saturdays, sundays and holidays keeping thier clients best interest at heart.
