The inspection also educated me on things like water heater codes (exhaust was out of code tolerance and there was major floor rot due to a leaky tank) as well as signs of water damage I wasn't familiar with.

Many might see the septic tank as an advantage avoiding a separate sewer bill that runs ~$40 - $50/month.I am really surprised there isn't some type of subsidy or program to help out homeowners that meet certain criteria in this predicament.

But Before you accept an oil tank "as is" I'd do a careful assessment.
