Owners are able to list their personal contact information, but I believe there is a stipulation that the contact must be local to the property4.

How would they get to any of these subsurface rights with 1/8th acre lots and barely 20 feet in any direction between any houses and any roads. 

I was told to go find someone to partner with, but would rather partner with someone who has already paid and they can take my part out of the earnings directly.

No, more specifically deals found through networking with local real estate professionals, finding pocket listings, direct mail, etc.

Like others in the post, interest income is portfolio income.What you can do is invest a self directed IRA/roth and put this money into notes.

The second home loan guidelines directly state "The Borrower must keep the property available primarily (i.e., more than half of the calendar year) for the Borrower’s personal use and enjoyment"This means that you can only book it out on STR platforms for half of the year (50% max occupancy), which really sets a cap on your max income. 

You can probably identify the builder of the subject property by contacting the City of Gatlinburg - they will have this information on file.Purely from an investment standpoint, building a cabin from scratch is by far your most expensive way to invest in the Smokies right now.

Tenant name, contact information, and address2.

@Jeff Hines - go with a direct lender and spread that $150K over multiple properties. 

Over 1 month with 124 Zillow potential tenant contacts, the property manager report showed no leads from Zillow and couldn't find tenants.
