I'm a newbie with 0 deals and I know bandit signs are effective.

Now I read this one: https://www.vox.com/2017/6/1/15724252/lebron-james... that basically says him being in Cleveland helps jobs within a couple miles of the stadium, and further out had no effect at all.2.

My wife and I own and self-manage several rentals in the local area.

Remember that Real Estate agents are self-employed so it is up to you to build your business.

My wife and I are making the leap into real estate investing but obviously we have questions. 1) Currently, to obtain funds for investing would it be more effective to create a LLC business or try to raise funds as an individual?

Often a Self Directed IRA (SDIRA) is presented as a better retirement and/or investing vehicle, especially for its ability to invest in real estate.

Does either way effect the interest rate of the loan? 

However, I've been self-employed since 2010. 

We are looking into how to put to use our IRA and ROTH IRA funds through Self Directed IRA investing, in either notes or rental properties.

You will then need to decide how to manage the property (self vs professional PM) but that should be included in your analysis.I am house hacking now but plan on moving out when my time is up so I can begin cash flowing.Best of luck!
