However, it is important that you do this in the proper way, or else you can potentially become a snake oil salesman like so many others out there.The premise is, obviously, to control real estate deals(greatly discounted deals) through a purchase and sale agreement and then resell the home or assign the contract to an end investor, allowing you to make a profit.

Once a septic company looks at it, you should be able to easily tell whether a plumber with a snake could do that kind of damage or not.I'm still not sure if insurance would cover a failing tank/field, but at least you can determine what specifically caused the failure.And be careful spending much money on new insurance. 

I got a plumbing company to come snake it out and they did a camera view and saw that the connection from PVC to the City Drain has a short clay pipe still there...thus with the ground shifting the PVC no longer drains clear to the City Drain.

Along with animal pee, feces and even snakes in the basement.

Every time I play with snakes....Thank you for bringing to light the pain (not to mention the thousands and thousands of fees) to optimize ones ROI through equity harvesting, equity-stripping, leveraging your assets or whatever the latest 'sophisticated' way is to grow.  

I can do the basic stuff myself (patch walls, replace doors, fix faucets, snake drains, etc.) 

Snake oil is snake oil.  

Land of gators, snakes and people I am starting to dislike.

We has him snake the line and he said there was no blockage and we should call the county.

I generally interview a lot of candidates and I verbally decline/weed out those who just on the surface would not qualify (smoker, guy with 15 snakes, person trying to re-negotiate the rent down, someone asking me if an eviction will be a problem or if I plan on calling their last landlord, or asking about a payment grace period).
