What international proprety selling site is the best?

So i need a good site for selling a proprety worldwide, where i can advertise the propreties for free. Under good site i mean mostly visited and free ads.

I recommend you post the ads different Local classifieds sites . if you want to post ads in USA then post on craigslist and back page other classified site available on net. if you want post ads on Canada then Kijiji best for you. you can post adds free.
