38 Rent out your stuff You can rent pretty much anything now, although space is still the most profitable "item", says Birtles. "Rent your driveway on parkatmyhouse.com if you live somewhere popular, or your possessions from a baby bath to your lawnmower on sites likerentnotbuy.co.uk and Zilok ," she advises. "Currently there are more items on offer than requests to lease things, but it's worth a try."
