Although you have not given much detail, my first hunch is that an airbnb would be more likely to generate more money for you, but that it will be more time consuming and hands on.

FYI, they inflate the costs on the warranties as well, depends on the year, make & model of the car but each one has a different base cost and I could charge whatever I got away with and the dealership profited the difference.

Would like recommendations on a reliable method to generate electricity without huge upfront cost. 

We’re trying to figure out how to avoid the short term gain tax implication of the sale since were in the highest bracket and that will basically eat into all of our profit.

I wish my thoughts were as profitable as @Jay Hinrichs!

Charlotte is a big city, rent to price ratios are generally less lucrative in cities and moreso in rural areas.The profitability rules for real estate don't work everywhere.

For example, if you want to generate a monthly cash flow of $3,000, then a good strategy to pursue is buying rental properties that generate cash flow until you reach that figure.

Many investors are adding value and generating 5-10 years worth of $100 monthly cash flows..in the 1st year of ownership. 

Will we be saying goodbye to our profit?

If the company complete the process of review in a positive way and is being announced that the landowner doesn't have enough money to pay for construction, then they look for lenders who can agree with the profitability of the project.
