Advice for potential house swappers.

DO . . . .

Be open minded about where you want to holiday. By ruling in places that are slightly off the beaten track you'll find matches more quickly.

Put away any items you might be anxious about, whether valuable for monetary or sentimental reasons. Putting them in a room and locking the door is perfectly acceptable, once you explain why the door's locked.

Make sure your car insurance policy covers the new driver.

Let the neighbours know what's going on. Not because you want them to snoop on your behalf (they will anyway) but because it's nice for your guests to have someone they can call on if stuck.

Swap with a family with children close to the ages of your own. Not only will there be toys but you'll be less anxious about letting your own run loose.

DON'T

Oversell your house. As in all transactions, it's best to under promise and over deliver.

Be insecure about whether yours is a des res or not. Be honest, put up the details and let them decide.

Hold out for the five-bedroom Florida villa with twin pool if you're offering a two up two down in Phibsborough. It can happen, but you'll have a higher take rate if your expectations aren't too high.

Rule out apartments. If you're looking to stay in a European city, you're more likely to get a swap if you'll stay in one.

Be afraid to ask as many questions as occur to you. By keeping up a constant flow of - usually - e-mails, you'll get a good feel for the family you are swapping with.
