I'm a big fan of value-add opportunities, whether it's buying something currently undervalued & fixing it up to my standards, or buying something that has additional income opportunities that have yet to be incorporated. 

Another option would be working with private lenders to see if they're open to your idea should you need additional funding. 

Here is a list of what adding ADUs in my CA market is typically a poor RE investment:1) The value added by the ADU addition is often significantly less than the cost of adding the ADU.

There had been a recent addition of, call it, Landlord LLC.

In addition to other tax strategies like a cost segregation study on the fully rented out house.

If you want to add it to places like affordablehousing.com then that gives you more exposure.  

- Are there any resources / you tube vidoes/ or additional BP Videos I should be looking at- If anyone is so kind, would anyone be able to give me a tutoring lesson for any hour, and if so, I am willing to throw a little money for their time.

In addition to that, platforms like HomeAdvisor or Angi are great for finding vetted professionals, and local builders associations or the Greater Beaumont Chamber of Commerce may have directories or recommendations. 

It's simple interest income (unless you do it in an IRA).

Pay attention to the duration.DM me if you want additional thoughts.Jeff
