I know on our pressure washer, there is a separate tank for soap.We normally just pressure wash with water, and its never left any type of hazzy/weird after substance!

Transmission shop that was a gas station across the street, makes me wonder about old gas tanks.

@Manley Woods- the age of the structure  doesnt  concern me  if I get a  solid inspection ...the more  concerning thing to me is the  systems in the  homes    ( furnace / pipes / sewer lines /  oil tank ? 

Quote from @Hector Serna: Quote from @Max Feinberg: @Hector Serna sounds like some of these things could be resolved/noticed before actually getting under contract  Looking for adviceThank you though For properties where the utilities are off, this can help you discover potential plumbing issues:At the home improvement stores, you should be able to find the fittings to make an adapter for connecting an air pressure tank or portable compressor to a hose bibb.

Do not worry about the age of hot water tanks, furnaces, - if you look at. big pictures, these are easy to replace.

A lot of people get nervous and tank a good deal and we could be missing something in translation here, but how hard did you have to work to get the deal? 

tanks, sam. unfortunately, on november 17th, i will be out of town. but keep me posted on the next one. i would like to attend

You have to stock it with water, empty the tanks, keep the batteries charged, replace the consumables, clean after every guest, etc.After accounting for delivery costs, parking costs, and personal time, it wasn't worth the hassle.

Hey Tank you @Mike D'Arrigo and @Jeff Schechter - really appreciate your insight on the subject. 

If not, then what happens when the market tanks (2007/08)?
