Some great ways of making residual income or passive income is to invest in real estate and rent out homes to people as everyone needs a home and a lot of people will pay you good money to rent out a home.
Other good ways of making residual income are, open a high yield savings account, invest in stocks and bonds, try affiliate marketing or peer to peer lending and write a book or write an e book and sell it online.
You can also make a good residual income by creating youtube videos and make income from the advertisements on those videos or create a blog and monetize the blog with ads such as media.net, Adsense or sell your own ad space.
If you get enough website traffic to your blog you can earn $50.00, $100.00, $200.00, $300.00 and even $1,000.00 per day from Adsense, Media.net or affiliate adverts or selling your own products.
I make around $500.00 to $600.00 per day from Adsense alone and get around 2 million visitors to my blog per month.
It took me around 8 years of blogging consistently though to get to that level of traffic and make the $500.00 to $600.00 per day.
For the first 2 years I barely made $1.00 per day but after very hard work and not giving up I now make more than my day job ever made me and I work less hours.
