This is why you see people trying to board aircrafts with everything from peacocks to snakes!

I opened the cleanout and the house was backed up, so I had a plumber snake it.

@Yeng Hawj From the home of the Thundering Herd...Anyway, odds are you and the "buyers" (quotes intention) might have very different views on the "market value" of your property. 

It seems that my options are:a) Cut the tree down but apparently this is not a guaranteed fix to stop future flooding;b) Snake the line every couple of months and cut and clear the tree roots from the line; here too this is not a guaranteed fix to stop future flooding; orc) Repair the entire sewer line .Has anyone dealt with this type of problem before?

I also got a quote from them to snake a main sewer drain and it came in very high.

Can't recall their snakes but they seem to show up whenever I said "San Diego sucks for investing" :)Personally I have all my stuff in houston.

I hope this doesn't sound like snake oil.

Toss it and install a new one for $100 after snaking the drain line.Or spend more than that on chemicals like drano and wait for it to gradually wear out to a point that you can pour in buckets of water to move the waste to the drain.

As a mentor myself, I am disgusted by these "snake oil salesmen" who fly in to sell a program of some sort and don't know the market and more importantly do not provide actual mentoring or guidance of any kind.
