NAS Lemoore is only growing, which means more active duty and civilians moving to the area.

A lawless place inhabited by a dreaded figure of mewling terror or obscure kakon: the diabolically clever professional tenant whose one maniacal goal in life is to get ultracheap or free housing by preying on their innocent, helpless landlord.

Instead I would either do something generic like finance or business which are both solid options for obtaining a high paying civilian job, or I would learn computer programing, SEO or something similar. 

The Army has the Civilian Skills Program that you can do during your last 120 days in the service.

After meeting with the commune inhabitants, paying them each $100 for the work they did (they actually got a lot of stuff out of the woods), we walked the site with the contractor.

I came to say the same thing many others are saying.IRC 121 only applies to the part of the house hack that you inhabit as your primary residence for at least 2 of the last 5 years at the date of sale. 

That would work but it hasn't been rehabbed and its inhabitable in its current condition. 

My job for the past 4 years has been an ER nurse with the majority of it as a civilian in Columbus, Ohio.

I just informed him that the lease was terminated and the unit was not inhabitable. 

Honestly, I'd like to sell the place but the inhabitants are not the best at keeping the property presentable - and are not responding to my calls.
