Offer got accepted in the south east suburb of Colorado. Inspection & Appraisal pending. The house doesn’t have Sump Pump installed and is facing NE with backyard sloping towards the house. The slope is currently hold by the retaining walls and covered with gravel stones. There are Sewage Valve Control, walking trails and houses on the top of the backyard slope.
What are the chances of getting basement flooded, water running towards the house during heavy rains and snow, standing water in lawn, soil erosion due to wind and precipitation due to sloppy backyard?
