Dogmom, if you can - hire a cleaning company to do a really thorough deep clean of your place, including cleaning the carpets. Your house needs to be sparkling.
Then if your interior paint is more than 5 or so years old, repaint everything in nice neutral colors. (Not just beige - could be a light sage green or pale yellow, especially in the bedrooms. It just shouldn't be any color that would scare anyone.) Paint all trim white semi-gloss.
If you have any wallpaper borders, take them down.
Look at your lighting, especially any lights in the entryway, dining room, and eating area in kitchen, if you have that, with a very critical eye. If they are builder's originals, replace with something better. Can be from Lowe's or H.D., doesn't have to break the bank, just something to update what you have.
Is your stove absolutely pristine? The deep-cleaning company can clean it, or you can do it yourself, but a yukky stove will really turn off the buyers.
Plus, as stated above, you need to show the dining room as a dining room. People really need to see proportion and scale, so you need a table and at least 4 chairs in there, six if there's room.
Plan on spending a certain amount to do these updates. It's a case of "it costs money to make money."
Get the dogs groomed, clipped short, and deodorized, which might help with the shedding, if that's an issue.
Has your realtor shown you a comp sheet of what the competition is selling for? (Not just "asking prices," you need to see "sold" prices.) You really need to know that to know that your price is in the ballpark. It doesn't matter what you paid for it or how much profit you hope to make. It's only worth what a buyer will pay for it. You have to make your house stand out from the competition at the same price point.
Good luck with it. It can certainly be a frustrating process these days.
Incidentally, "Audi B" that I've mentioned in another thread has moved here to the Outer Banks from Ohio. We were chatting about where she lived here, and it turns out she and her husband are renting because they couldn't sell the Ohio place. The Ohio place has now been on the market for about a year.
Ouch to paying rent and mortgage BOTH
I laughed hard at this one. I had this exact same experience. My agent was frantically trying to txt me to let me know an agent was bring someone over. Luckily I had a towel around me when I stepped out of the shower. The girl with the agent blushed scarlet. She ended up buying the place. Not sure if this situation had anything to do with it???
