May I offer my two cents worth?? I am a realtor and owner in a well known Seattle Real Estate office. I've been in the business for over 15 years and I'm going to be blunt. Remember, I'm just trying to help - don't take my words personally.
First of all; the kitchen, dining room and bedroom look excellent! Very well decorated, your taste in furniture is very nice and it shows in the pics very well!!
The living room is much too crowded. You definately need to box up the videos, cd's, etc around the TV. In fact, it's barely acceptable to have a TV in the room unless it's in a cabinet that closes so you can't see it unless you have it open to watch. If a cabinet will work in your new home perhaps now is the time to buy one. Over half the furniture in the living room should be put into storage.
The other negative, as others have stated, is that there is no usable back yard.
That being said - any $$ you put in now will probably not bring up the value of your home enough to cover the costs. A professional stager can cost lots of money - as much as replacing flooring in the bath+. Your home is not going to sell for that much more, if any. I would recommend a stager if you needed it but honestly you have good taste in furniture, your home is clean - why spend the extra $$?
Listen to your realtor - lower the price accordingly. In fact, I would look at the multiple or drive around your neighborhood. Which realtor has the most listings in your area?? give them a call and have them do a Market Analysis. Just because you have a signed listing does NOT mean you have to stay with your current realtor. BUT BUT BUT - if your current realtor has been giving you good advice all along and you're not following it (lowering the price, etc) then you should just start listening to your realtor.
I'm sorry if I sound like I'm tsk, tsking but your home is only worth what a buyer is willing to pay. Not what you think it should be worth. Big hugs and best of luck!!! The perfect buyer is on their way, be ready with a good price and a good showing!
