A common misconception is that you have to put down 20% of the purchase price.

Many Airbnb guests will want common utilities unless it is in a remote are where you go as a sot to sleep while hiking the area. 

On the other hand, you might find a common reason that a few of your potential investors are not investing that might change your own thoughts on the deal.

Can you then advertise the land to resell to another buyer (cash) for $120k and then pay off the original seller, and pocket the $20k?

The most common is leaning on your agent for their expert advice.

First, I looked at the most common solutions: Quickbooks, Stessa, Digb, RentRedi and finally went with Stessa because it was free.

The property is placed in service when you first advertise the property for rent. 

It's expected and common for MTRs to have utilities included.

IE its common in so many areas that the 500k home in Wis sits on a 75k or 100k lot and 300 to 400k is the cost to construct say at 150 to 200 a foot..
