I am looking to supplement my income with real estate investment.

Our long term goal is to be able to supplement our income using rental properties.

Hawkins II and I have decided to become a real estate investor, so that I can supplement my income, where I would like to make an extra $75,000 a year.I am currently located in the Lawrenceville, Georgia area.

You can use Everbooked and AirDNA to get high level estimates for your ADR and Occupancy rates but in the end, I usually like to supplement (especially if I'm getting serious about a property) with good old fashion legwork with calls to local property management companies and review of nearby listings on Airbnb/VRBO.  

If you want to learn more about landlording and taxation and liability (LLC) - here are some books to get you started on this: for accounting and taxes - Every Landlord's Tax Deduction Guide (make sure to get the latest edition) (and you can supplement that with Deduct It!

LIQUIDITY EVENT: Good segway here, but depending on the deal, some investors can receive a good chunk of their principal during a REFi or Supplemental Loan event.

Would you recommend just going down to a mobile home park over a weekend and inspecting the homes myself or can I also get a property inspector on top of that to supplement my own inspection?

At the second meeting, the park owner may take into account the information on comparable parks provided by the committee, may supplement the information provided to the committee at the first meeting, and may modify his or her position, but the park owner may not change the information provided to the committee at the first meeting.

Hehas made a good "supplemental" income from this.

Then after I do leave, I can start flipping since I'll have more time and also the supplemental income from the rentals.
