Don't buy anything with an oil tank that you haven't had a soil test done.

I'd suggest taking a look underneath to see what's going on. 

Should I first write one paragraph in english and underneath the paragraph translate in spanish or should I have one side of the page in english and other side of page translated in Spanish?

Justin, Both of any of the following scenarios could have happened:1- There was a long term leak under the slab (either clean water or sewer leak, or both) that have cause the foundation to settle, and thus cause even more damage to the rest of the pipe lines.2- The settlement of the foundation due to non-leak reasons (such as bad soil mechanics) might have caused the pipes to break or crack.3- Lifting the foundation causing the pipes crack.4- Combination of all aboveI have had this property for a few weeks, so it has been out of my control.The lowest quotes I have got for fully replacing the sewer line and clean water line is about $13.5K for a 1800 SF house.My deductible is about $2500 if the insurance would cover it.

Now, it seems that the sheathing underneath is probably rotten and at the least the porch will need a new roof. 

It seem the soil lateral force pushing the foundation wall into the house.

@Hattie Dizmond foundation issues in the DFWarea is something I have notice growing up here and I know the soil shifts just never applied it to real estate.

Part of this was because I†trusted†him enough to follow through with the contract, which would end next year, but the other half was that I didn’t expect this to happen underneath my own ears.

Here in the Dallas area, our soils tend to expand and contract as moisture changes, so foundation problems are quite common.

I believe there is a wooden roof underneath and they put Asphalt over it..
