Depending on how bad is the foundation state (how many inches you have to correct), is very possible the sewer line will disconnect/break in the horizontal portions.

I took off for the weekend and really disconnected from everything.I look for Tax sale lists =, which is going to be a small subset of the regular properties with delinquent taxes.  

The manager told me the owner of the park had required all of the home disconnect all waste water except toilets from the septic because the leach fields were failing.

That is the quickest way to get someone to disconnect right away, find out first and foremost if they are still living at the property you are calling in reference do, find out if they have three minutes to talk, and then find out as much information about the house as possible, leading to would they be interested in selling if you could come to terms on price, and close by setting an appointment to go out and look at the house.

@Owen D.Rally must of been giving them away too cheap because the number is disconnected :) Took a bit of calling around but I already found one guy, Better Living Appraisal Services in CB, which will do it for $500. 

If you don't want to flush 32 times, disconnect the supply hose from the tank and let it run into a bucket.  

Because if you're buying a new one, that means you're disconnecting the old and reconnecting the new.  

I'm in the process of buying a foreclosure that had the main circuit breaker (disconnect) stolen.

You have a disconnect with your goal right there.

Listings never show the corroded broken pipes in the attic, the sagging roof and squirrel chewed soffit, missing water heater or disconnected toilet.
