Trenton has a massive air base which offers steady good playing jobs, so the economy of the town seem to be stable. 

Plumbers routinely do an air pressure test on the water lines, if freezing pipes are an issue.

One such property was sold in 2010 for $141,000, and had new roof, new siding, new windows, 2 new full baths, new kitchen, new 200 amp electric service, and new heat and central air. 

I currently serve in the Air force Reserve and am a full time Nursing student at South Alabama University in Mobile.

From personal experience most just pull their ARVout of thin air.

I'm active duty Air Force, debt free and I'm looking to invest in rental property in Memphis.

Getting Real With Our Budgets:I think most people just randomly pick a budget number out of thin air and say "I have $X to market".

If your lines are indoor in well-insulated space, I'd still go with the higher R-value stuff- why not spend a few extra bucks if it'll help reduce the risk of freeze-burst damage, which can be extremely costly?

I visited some folks near Phoenix that moved from here, they bought a very nice double wide and the park was a bit of a country club, golf, tennis, indoor pool, pretty nice, except they had no grass.

For instance, I believe the AIR lease calls for capital improvements to be amortized over 12 years and the tenant to pay not more than 1/144 of the cost each month.
