How to find a buyer for a house that needs a lot of work.

[Jeff Haak]

I am hoping to get a few suggestions on how to go about finding the right buyer for a house that family members are looking to sell and needs quite a bit of work.  At this point the owners are just looking to get out of the house and downsize to something more manageable, but need to sell this in order to do so.  Would the best route be to get a local real estate agent to sell the house, or would selling it without one possibly be a better option? 

Just to give everyone an idea of the scope of work needed, it includes new siding, roof, plumbing, extensive electrical work, full gut bathroom and kitchen, possible mold issues, and a few other smaller issues. The house is 2000 soft, 4 bedrooms, 2 bath with just under an acre of land.

Any suggestions on how to go about this would be greatly appreciated.
