There are a lot of good real estate agents selling homes. The popular idea is that the agent that sells the most houses would be the best agent to sell yours. You need to find an agent who is easy to contact. Do they answer the phone when you call them or do you have to wait 4 or more hours to hear back from them. Do they have assistants that you actually work with. Wouldn't it be better to work with an agent than an assistant?
Most buyers want to see all the houses that fit their criteria. They eliminate houses that don't have enough square footage, large enough dining areas, bedrooms, and bathrooms. Photos help sell homes, but information to keep them interested is price and data. A real estate agent needs to make sure all categories are filled out on the listing if possible. Sometimes they aren't allowed access to measure the house (a tenant occupied house where the tenants are left as much privacy as possible.) Location is another important feature. A location close enough to schools for the children to walk, good access to shopping and freeways is a plus. Most people want quiet and private. If there is a way to add privacy that helps. Some times the market changes seasonally. There are typically more buyers looking when the weather warms up so they don't have to move in rain or snow. Some buyers have to sell their homes before they can buy, that translates to a 2 month lag waiting for someone who has an offer on their property before they can seriously start looking and making offers. Get your house ready to sell before you put it on the market. Some people have a hard time visualizing a house they way they would like it if it needs a few things.
When I think of your question, I often wonder if the house is ready to sell. Is there something that would make the sale time take longer?
