This is because I'm concerned that even though the things in the house I can see look great things like the electrical, plumbing, or the foundation may need major repair if not immediately relatively soon. 

We have had a pipe burst during the cold winter months, the roof needed to be replaced (thankfully covered by our insurance), and some issues with electrical, which hasn't been majorly updated since it was built in 1973. 

Of course not, but required items such as electric, water, gas, and plumbing all need to be in working order.

Quote from @Aaron Wolman: I would call the companies (gas/water/electric) to get estimates, or an estimator out there.

Less electricity, no chemicals needed (drain easily and have the proper systems for it), and can have  the same effect. 

The property next to me is a 1 acre lot, it has a Well, Septic and Power, but no structure.

. - So, that leaves electric & gas.

I agree with Nathan (don't forget to price running extra water, sewer and electrical lines).  

The city is among a number of nodes for Tesla suppliers popping up throughout the Austin metro as a result of the so-called "Tesla effect" — which is shorthand for the trend of electric vehicle suppliers flocking to the region in response to Tesla's mammoth presence in eastern Travis County, where it has a gigafactory and headquarters.

So you would spend around $25-$30k a month (this was 15 years ago) on police details and require union gate and non union gate if you had non union workforce as well.In DC area, the utility providers are a huge challenge, whether getting permanent power, or water/sewer service etc - good luck.
