If you live near one of the venues for the Ryder Cup you could earn money by renting out your home for the duration of the tournament.
The venue for the 2012 Ryder Cup is the Medinah Country Club in Chicago, Illinois. The venue for the 2014 Ryder Cup is Gleneagles in Scotland.
If you go to Ryder Cup Accommodation you will find a site where you can list your home for rent. At the time of writing this (Sept 2011) the site is already receiving visitors looking for accommodation for both events, so now is a great time to add your home to the site.
