If you have to close , first install a 275 gallon above ground tank away from the underground tank.  

I read that the new models use about 10 gallons per wash, while those old school top loaders (called agitators) can use to to 40.

Usually pay around $900 installed around here for 40 GALLON gas, which to me seems reasonable.

Include oil in your lease "up to xxxx gallons annually".

My wife and I bought gallons and bottles of water for all 3 tenants so they could at least have a drink and brush their teeth.

Economists say about 65 dollars a barrel is optimum where the oil businesses can still make money but the gas pump prices to consumers are not too high.If the barrel pricing goes really high again then it can make a boom for oil industry areas such as certain parts of Texas but have a much larger negative affect on the rest of the country with per gallon gas prices too high.Example where I live in GA 87 octane is about 2.18 a gallon.

If you need to replace a septic tank it's about $4k for a 1000 gallon.

If you can do some sweat equity like repainting or replacing carpet with laminate/luxury vinyl planks you could boost the value and desire ability for a couple thousand dollars. 5 gallons of paint is like $120 and covers several rooms.

It's about 50% off per gallon if not more, and they keep track of my colors.
