One risk I see is in my area oil prices being low is a bad thing.  

When the collateral is crops growing or to be grown, timber to be cut or minerals or the like (including oil and gas) or accounts subject to subdivision (5) of Section 9103, in the office where a mortgage on the real estate would be recorded.

Oil tank problems

When market went down and oil went to $25  a barrel my unit went unrented for 3 months.  

Flat pure white on the ceilings, eggshell on the walls and a semi-gloss latex or satin (if you can) oil on the trim/doors/cabinets for durability and easy clean up. 

No stink will stand up to the hardwood being sanded down, filled, sealed with oil-based polyurethane, and then refinished with another two coats.

Two coats of oil based KILZ over the entire house including the ceilings and floors in some rooms and ripping out all of the old carpet/flooring solved the problem.

We are right in the tumultuous Oil market , but also have a popular University and Airforce Base.

Also I think certain commodities look reasonable now like oil and gas.

He could have invested a major stake in oil and gas operations allowing him to write off the majority of his investment in the first year.
