What are the best passive income sources that don't require an initial investment?

There are several passive income sources that don't require an initial investment, including:

Writing an ebook: You can write an ebook on a topic that you are passionate about and sell it on platforms like Amazon Kindle Direct Publishing, Barnes & Noble Press, or Smashwords. Once you have published your ebook, you can earn passive income from the sales.

Creating an online course: You can create an online course on a subject that you are knowledgeable about and sell it on platforms like Udemy or Skillshare. Once you have created the course, you can earn passive income from the sales.

Renting out a room on Airbnb: If you have an extra room in your house or apartment, you can rent it out on Airbnb and earn passive income from the bookings.

Investing in dividendpaying stocks: You can invest in stocks that pay dividends, which are a portion of a company's profits that are paid out to shareholders. Over time, the dividends can provide a source of passive income.

Creating a YouTube channel: You can create a YouTube channel and monetize it by running ads on your videos. Once you have built up a following, you can earn passive income from the ad revenue.

Investing in a highyield savings account or CD: You can earn passive income by investing in a highyield savings account or CD, which offer higher interest rates than traditional savings accounts.

It's important to keep in mind that even passive income sources require some level of effort and work upfront. However, once you have set up the source of passive income, it can provide ongoing income with minimal ongoing effort.
