1. Swapping homes for temporary periods, usually at the same time and usually for holidays (vacations). As 'home exchange' has been used to describe this type of service for at least 60 years, this is still what is most commonly associated with the phrases, 'home exchange', 'house swap' (and variations) - and is what this blog (and Home Base Holidays) is all about. 2. Swapping council houses (property owned by and rented from local authorities) or privately owned homes permanently. This is a common practice in the UK and a number of sites cater for both types of exchange. 3. Part exchange an old property for a newly built home. This is an incentive that house builders sometimes use to encourage sales of new homes. 4. Permanent swap of homes rather than selling. This seems to have become very popular in the USA especially due to the slow down in the housing market. A number of sites have sprung up to offer this service recently, to match people who want to sell their homes but are unable to find buyers with others in the same situation. 5.
