Would your family member be willing to watch a program on television? There are some very good ones on this subject. One of them is called "sell this house"on A&E and the other is called "Real Estate Intervention",on HGTV Everything your relative needs to know is in these programs. If they don't have cable they are also available online.
I know it's hard to be direct about repair things and clutter. There are also books on the subject that will help.
I would push the selling agent for some feedback. Can they not pack up or clean up most of the toys? As far as the closets put a note in the listing offering a 100 or so in concessions for the closet doors. Better yet for approximately 500 they could offer a home warranty. That goes along way with buyers from the standpoint it puts their minds at ease on buying an older home. American Home Shield has a good program but, investigate for yourself whom you would use. They pay nothing up front and the money comes out at closing. Better yet once registered the home is covered even while it is for sale. So if something goes wrong before it is sold it is still covered.
Coldwell Banker Triad
1. Try to declutter the house. When people visit the house and they the mess, it's an instant turn off.
2. Perhaps the seller can advertise the property on craigslist.org or any other sites or newspapers that will bring more visitors.
3. Hassle the agent to provide more feedback. The agent must follow up after every showing and provide feedback to the seller. It's their job.
4. Hire a professional stager. Stagers can do wonders to properties that don't sell.
5. You can always lower the price.
Hopefully these tips will help.
