Does anyone know the best place to sell an existing franchise? My brother in law has a fresh fast food restaraunt that he wants to sell and I did not know the best place to advertise the business for sale.

Most franchises have rules about selling your franchise i.e. cant advertise the name of the franchise, you must give the franchisor the right of first refusal etc. I would check the UFOC for specifics but I would go to the franchisor first

If there are forums like this one that are focused on the franchises niche you may want to explore that if not I would advertise on BizBuySell - The Internet's Largest Business for Sale Marketplace or one of the other online business for sale classifieds sites.

Some Franchisors help you sell the franchises but I think your best bet as the previous post explained is to put it up for sale online or if you do not feel comfortable dealing with potential buyers - find a business broker.

Business brokers get up to 10% of the purchase price and in my experience they provide little value I would try to sell it yourself and use escrow.com or some other similar service to protect your investment.
