Use Hardiebacker or Durock cement board.

Normally, you have cement foundation that goes above ground, then the siding starts, so it doesn't rot. 

My plumber removed the pipe from underneath the house and it looked like the tenant poured cement down the drain.

I was already doubtful I had any claim under the title insurance policy and this has just cemented that. 

@Theresa HarrisGrab a $4 bottle of Concrete glue from the hardware store, squirt half it in the water you’re using to mix with the dry cement.

Is letting his dog go upstairs and **** all over the attic (we have pictures)We don't want cement poured down our toilet or anything, but we NEED to move in this place.Should we file for eviction right away or let him live there till he leaves in Octoberish (but what will my dad do?)

It sounds like your situation is easy to remedy with vinyl cement patch and waterproofing paint.I am not sure courts would consider water in the basement a habitability issue.

And painting the garage door white, gives you a nice clean left-to-right consistency across the house.I was thinking it would look nice to paint the red cement porch area black, and the window trim black, too.The black blob over the garage door is supposed to be a large black really cool light fixture. 

This summer I will power wash and paint the foundation cement out front as it’s chipping away.

For instance, in CA when it starts to rain, you will often be invaded by these tiny ants we call cement ants - they usually live under sidewalks or cement porches, and when their ant condos get flooded, they invade your home.
