Your best deals, but the most work, will come from properties not formerly listed as for sale. Contacting the owners of abandoned or run-down properties might uncover a deal without the hassle of competition from other investors. Once you have the address of a property, find your county assessor’s page on the internet for ownership information. The assessor’s page will have other useful information like previous sales and house characteristics.
If you have specialized knowledge in a certain topic, you can put together an online course to teach others. For example, if you have experience in real estate investing, you can create an online course “Real Estate Investing 101”. The benefit of an online course is that once you create the course material, you can sell it to as many people as you want.
