When is a retaining wall needed (with pics) ?

[Jordan Thompson]

Good morning BP!

I’m considering purchasing a duplex but noticed some un-retained land next to the driveway that looks suspicious. A power pole is about 2-3 feet or so behind the top, and I think the septic tank is 10 ish feet behind that.

The property seems like a good deal; over 8% CoC return and low $300/ month of pure cash flow but that could be gone quickly with this problem.

Any experience stories or advice from the experts?  

Thanks!
