@Bryan OttesonThe tenant has already been notified that the property will be rendered unoccupied upon closing.Do you still think he'll be up for signing anything?

If I were to invest out in the boonies and if something ever happened to the market (such as the only job source leaving town) or the some sort of catastrophic damage that happened to the house that the insurance didn't cover and basically render the land to the point that no one wants it, what would be the exit options.

If you are in CA, then the upcoming correction might render a fixer-upper less valuable in a few years than it would be now, unless you're looking at more of a live-in flip situation where you'd be in and out in a year or less. 

Umbrella policies seem to require the underlying dwelling fire to go up to a limit of at least 300K, so using that carrier would render the umbrella policy useless.

Though you may owe money for the appraisal or other services that were already rendered. 

Getting everyone under contract with a hypothetical rendering, getting the development approved, and partnering with a developer as a percentage partner. 

)Is it necessary to also provide 3D renderings for inside and out?

I may fill up your voicemail box and torment you endlessly, until you need to change your phone number, rendering all your signs useless.

Will the market change and render your projections obsolete?

Remember this is very rough and more like bubble diagrams and maybe a rendering or two that are low resolution.
