Tax Lien vs Note Investing

[David New]

I'm looking to start investing somewhat passively on the side of my normal day to day job. I've been intrigued by the idea of note investing and tax liens. Has anyone here have experience with both? What are the pros and cons to each? Does one offer better returns than another? Is one more suited to do part time than another one would? 

I have been looking at a handful of courses online for each but wanted to determine which route I would like to go first. Any feedback someone could give me would be appreciated.

Here are some of my thoughts which people can addd too

Note investing:

Pros:

1. year round in states you prefer

2. Many aspects, firsts, seconds, performing, non performing, seller financing, hard money lending.

3. Greater opportunity for higher profits

Cons:

1. Not passive

2. Need to build a team

3. Systems intensive and higher overhead

4. Higher risk

5. Licensing

Tax liens:

Pros

1. Passive

2. Less volatile

3. Low barrier entity

Cons

1. At mercy of jurisdiction for sales

2. Very high competition

3. Cannot be done online in every location
