     Home exchanges are not new. At least one group, Intervac, has been making such an arrangement

easier since 1953. But trading online is gaining popularity these days, with several sites in operation,

including Home Exchanges. Founded in 1992, with about 28,000 listings, this company bills itself as the

world's largest home exchange club.

     The annual fee is usually less than US$100. Members can access thousands of sites for apartments,

cottages, urban homes and farms around the world. Original contact is made through e-mail, with the

following communication usually by phone. Before a match is made, potential swappers tend to discuss a

lot.

     However, the concept may sound risky to some people. What about theft? Damage? These are

reasonable causes for concern, but equally unlikely. As one swapper puts it, "Nobody is going to fly across the ocean or drive 600 miles to come to steal your TV. Besides, at the same time they're staying in your

home, you are staying in their home."

     Exchange sites recommend that swappers discuss such matters ahead of time. They may fill out an

agreement spelling out who shoulders which responsibilities if a problem arises. It does not matter if the

agreement would hold up in court, but it does give the exchangers a little satisfaction.

     Generally, the biggest complaint among home exchangers has to do with different standards of

cleanliness. Swappers are supposed to make sure their home is in order before they leave, but one

person's idea of "clean" may be more forgiving than another's. Some owners say if they come back to a

less-than-sparkling kitchen, it may be inconvenient but would not sour them on future exchanges.
