Sell your parking area

If you live in an area where parking is expensive yet have got an empty parking space in your driveway, you could rent it on a monthly basis. Online parking marketplaces will allow you to list your space in their databases, and set a monthly price for it. You can also set restrictions on use if you're likely to need the space yourself during the weekend or at certain times of year. So, if you don't use your driveway, and you live in a built-up area, you might just be sitting on a tidy little earner.

How much? You should be able to take just slightly less than the going parking price in your area. Spaces in London generally go for around £200 per month, though security is also a factor in determining price.
