Underground Oil Tank Removal (Test results came back negative and it's in the front yard under grass)2.

@Jay Hinrichs Sooo, my rainforest killing, kicking grammy out of her house, loan shark you!!

Assuming I own all the excavation equipment and can install all the septic tanks myself. 

:) I don't mind learning from failures, but first project tanking would really be a major setback, even financially.Many thanks in advance!

Sun hits the panels, glycol gets hot and goes to a storage tank inside, then into the radiant floors.

Environmental health indicated that the septic tanks are 4/6 1987 and 2/6 2001 but there is sewer to fall back on

You are not only jumping into the deep end, but into shark-infested waters, during a hurricane.

Maybe in the beginning a 1 star can tank you, but over time, if you have an average very close 5 on a 5 star system you will be fine.

Properties in SF and Seattle are tanking as we speak, but sellers are just taking their houses off the market, leaving supply low.Should I give up and just buy whatever the asking price is and let it eat half my income?

Water heaters, softeners, toilet tanks, and anything else in the house that holds water. 2.
