Looks as though you've gotten some wonderful advice here already! I have a few thoughts about your questions. Of course, I'm sure that your Realtor has discussed pricing the home competitively, presenting it in excellent condition, and making sure it's got the best photographs and video tour possible; That's the minimum in a buyer's market.
I work with homeowners and Realtors to present homes in their best light, and increase buyer appeal. In my experience, the smaller houses in a neighborhood usually sell to down-sizers or small families who want to be in a neighborhood of larger homes, but don't want a large home for themselves. I have helped many clients maximize their smaller home, to appeal to a larger pool of buyers (all the while keeping in mind who will be looking for a home that size.) Appealing to the down-sizers and families on the way up is very similar. Your goal is to make your home seem larger by eliminating any extraneous furnishings or decor, as well as simplify your decor to make the home seem easy-care for a young family or retirees.
I'm sure that I can offer more suggestions and ideas if you'd like. Feel free to contact me directly, or respond here. I love what I do and am always happy to help out.
