I have some basic ideas of what I would like in mine, underground oil tanker scan, septic tank check, setback measurement, etc.

When I converted a property from oil heat and hot water to gas, I asked the gas company about whether tankless would be a possibility.

We had a tankless on the oil furnace and I was always running out of hot water.

i live in oil country, and when the boom busted, i ended up in a better paying job then i was making in the oil service company that i was a mechanic for, but the properties realy havent dropped in price yet, though i did find some excellent priced land, 50% off everywhere else around here.  

I am not an electrician, but was able to navigate the swap from oil hot water boiler to electric baseboard heat. hopefully you find this helpful and relevant. 

Unfortunately I've been laid off with the slow down in the oil market.  

This one is ideal if you have to share what you do with someone who may be skeptical of business or capitalism ( I use this if they are serving vegan food, humus and smell of patchouli oil)...Congrats on your success housing others and .....Best of luck.

Oil, gold, diamonds, wood and other natural resources were stolen from the earth and sold for lots of money.

Same thing with Oil.

Balloon" framing (1920's I believe).Radon.Plaster and lathe instead of sheet rock (pre 1950's) or plaster and wire mesh variations (50's) more solid than sheetrock but a real b*tch to repair or demo if you're remodeling.You've got Galvy plumbing but also need to look out for other kinds of outdated plumbing like clay sewer lines (pre-1930's, prone to collapsing, bellies, root intrusion), cast iron (1950's, often rusted and/or cracked by now), and PB (polybutylene, gray-colored water pipes, 1980's, prone to rapid degradation and subsequent bursting, mostly gone by now).Buried Oil Tanks-- Do you have those there?
