@Jordan Whitworth, in a normal situation, I would say you're on the right path.

We normally purchase land like yours and lease them out to the solar developer, but we have been gathering data and tools necessary to identify top-tier land.

It looks like the previous owner extended the deck to twice it's normal size because they had to add a wood slab to keep the power service lines from dangling down (separate hazard issue that I'm worried about).

I normally forbid tenants from operating a business from a residential property.

I still get some vendors that mail me paper invoices or have our accountant/bookkeeper scan in documents however at this time I outsource my bookkeeping and I'm guessing they despise scanning as much as I do as they normally do not do it and I have to micromanage it to make sure bills get paid timely. 

People with lower incomes have less savings so it only takes one car repair and your rent's late.

I have read here that there's a risk during an eviction conflict that the tenant can make a payment you would not accept normally.

@Ramon Mota  It's really the same as a normal RE transaction except you provide the financing and not a bank.The buyer gets title and ownership and you place a lien on the property, securing your interest. 

We see the Car there everyday and night and the new person brought me last months rent.On top of that we are now smelling Cigarette smoke through the walls since they ”moved in.”What should I do?

The costs are Exactly the same as buying any other property.....all debts and liens need to be paid off at closing along with your normal closing costs.
