Even just a clay liner is fine which I see a lot in 40s-60s houses. 

You can draw each wall manually or simply take pictures with your phone or tablet of each corner and it will draw the walls automatically.

Shoot 70 out of 100 clays on a sporting course when everyone else is shooting 50-60 2 weeks ago. 

Check box gutters and consider hopping over them when you do a roof replacement. check the sewer line because it was probably clay and if no one replaced it's probably cracked/collapsing. 

I manage rental property and use Eric Clay all the time.

@Melanie Parkham we have a lot of old homes in Milwaukee, 60-120 years with clay tile sewer laterals.

And even from there, laying tile can be a ~$10/psf endeavor for cheap tiles to ~$100/psf for handmade clay tiles and labor.Now somewhat real numbers: we are currently in a about 3,300 rehab down to studs.  

These issues are a lot more common with homes built after WW2 in the 1950s and 60s - the basements were machine dug and deeper, which allows for more force from expansive (clay) soilds.

I remember an engineer telling me that there was rock on the west side of 35 and victorian clay soil on the  east.

@Clay S, The IRS is not concerned with the number of properties or TIC syndications or DSTs you buy (other than the statute limitations of the 45 day list).
