It was a Snake with a Root Auger. 

They will just continue to complain and make a big deal out of everything, and will be a massive drain on your time and resources. 

hi jeremy. i would agree with bill. i would bet the downspout was draining right next to the foundation which is completely against the whole point of a downspout. you want to devert water away from the house, not dump huge amounts of water right next to the house......lol. i would have to say, from a home inspectors point of view, the water has probably eroded the soil beneath the footing and caused the footing to collapse, allowing the foundation to crack and collapse with it. you could get away with just tuck pointing it, but it will come back. the repairs could be extensive and expensive and jacking the house could be involved. it could also involve a small area of the footing/ foundation and allow you to rebuild just that area too. hard to say without actually being there. check with a local structural engineer and weigh the costs verses the value of the house. after all, thats what real estate investing gets down to. good luck to you

A tub with access to the drain pipe can be replaced in a few hours if everything goes right.

A single vacancy will drain funds quickly.

What condition are drain lines?

It basically is as it has a wood heater, running water, sewage drain, and electricity.

Ended up being a collapsed drain pipe.

I got cold feet after the inspection revealed issues in the bottom unit including the 2 gas space heaters not functioning (going into winter), the flooring caving into a sinkhole in the kitchen without the ability to determine cause, and all the drains outside leading to the sewer were collapsed causing fear of flooding.

I have a rental property that has a unique roof as seen below:Leaves clog this drain and the roof in the upstairs apartment leaks.
