@Erik Dofelmier- likely priced to high ...maybe lower the upfront deposit from 3 mos to 2 mos ...renters will want to see the  product before  spending energy / time and money 

I'm also curious how much it costs to prepare the land and install plumbing, electricity, and concrete (driveway, walkways, patios).I'd love all the insights I can get from anyone that has experience doing this.

"wets" likes water, storm, sewer, and "dries/dry" like gas, electric, etc.

On top of that, you have other costs, such as permit, water, electricals, sewage system, etc... 

Each one has exciting new projects on the horizon, like a minor-league baseball stadium in Spartanburg, South Carolina, entertainment districts in Huntsville, Alabama and Alpharetta, Georgia, and even economic development, like electric vehicle manufacturing in Bowling Green, Kentucky.FULL STORY

Electricity being cut off way to often because of failing trees.

Some of my leases need to be updated, including increasing security when increasing rent; putting in clear violations (such as tenants using electrical heaters, which is a fire hazard); having a reliable attorney ready should any legal issues arise.

I also wouldnt worry about the electrical drain unless you are converting it to an MTR and paying electricity. 

Overhead door location and height, width and depth of space, bathroom locations and electrical and plumbing rough-ins etc.

The unit is a 2 bed 1 bath with a 20 gallon electric water heater.
