How it works
Intervac offers a free 20-day trial membership and charges an annual membership fee of US$100.
Members create a profile with information and photos of themselves and the residence they have to swap including amenities such as automobile use, the size of their family, the dates and length desired, and the destination desired. Members can then search for houses that fit their desires or wait until they are contacted by others. Like most homestays, terms of the stay are negotiated in advance.

History
Intervac was the first home exchange network, founded in 1953 in Switzerland by several teachers that wanted to travel internationally with a limited budget during their summer vacations.
