There is a surprising variety of things you can do to learn extra money for very little money. Options include acting as an extra in movies, donating blood (or sperm or eggs), taking care of the house, or taking care of people’s pets.

The chances of earning money in these ways will vary depending on where you live. For example, the rules about donating blood etc. vary from country to country, but in many places you can earn a useful little extra income this way.

The house session is another option in certain areas. In some cities there is an emerging market of people willing to live in their own home if they have moved temporarily or are having difficulty selling the home. This usually means you can live rent-free for a period. You may be expected to show potential buyers around and obviously move in on short notice. Other ways to live rent-free could be taking a seasonal job at a ski resort; again, not a great source of income, but certainly good for avoiding expenses.

Pet sitting and dog walking are also useful ways to earn some extra cash. Many people will pay you to walk their dogs during the day or to visit and feed their pets while they are on vacation. Again, this is a useful way to earn some extra money on a small investment, the main cost being to take out proper insurance.

If you’re looking to earn extra money and can’t afford to invest too much, there are a variety of ways you can earn extra income. These are often related to where you live, so the options will vary from country to country, but one thing is for sure: the internet is worldwide and is used to make a lot of money with little to no investment. This can be done by capitalizing your money from the comfort of your home.
