I am considering selling the rental cabins individually and retaining the house. 

I would start looking at your network and explore where you can grow in this area with likeminded individuals. 

Land has always intrigued me, so I wanted to learn a little more about purchases large tracts of land (ag, farms, timber, etc.) as another investing strategy.With BP being such a wealth of information and helpful people, I thought I'd post this to see if anyone could recommend books, podcasts or individuals to connect to.Thanks!

Their powers are granted by the state in each individual charter.

@Marshall Shen On a single family house, unless you are renting individual rooms you won't have utility expenses. 

For example, the way NH does things,  pre TCJA it was more expensive for a high income tax individual to pay out profits as a dividend from their SCorp, than it was to just pay the employment taxes and pay it out as wages.

I am very aware of prohibited transactions and disqualified individuals. 

There are many kinds of hard money companies and individual lenders, there are no "standard" HMLs. 

If they are good, and they protect your asset, collect your rent and manage all of the Maintenance for a reasonable price they are worth it if you have a decent size portfolio. 1-5 units is manageable by an individual.

I know you mentioned duplex so one side can help pay your rent, but if you own a single family and rent out individual rooms, you can do just as well, or better, and have more options.I have a wife and daughter, and my wife isn't down with the idea, but when I was younger that is what I did and it paid for my housing and living all though college.
