You are aware of the POTENTIAL problems;  are there things you can do to make it better, like ensuring water runoff is not making it worse.  

Most water intrusion is due to improper drainage and can be addressed simply by ensuring the gutters are in good repair, have downspouts and extensions and also make sure that the soil is graded away from the foundation.

Easy to install, looks great, easy to clean, wears well and holds up to water.

My first few inspections were helpful to help understand building systems and routine maintenance schedules (don’t have to worry about that stuff when you’re a renter.)Sadly inspections afterward, for investment properties, only turn up obvious items that’s hard to miss if you personally walk the property looking in the nooks and crannies.Rot, poor wiring, improper framing, water leaks, etc that are behind the walls is when I’ve gotten into trouble.

Most surface owners here make money through damage payments from the mineral owners, by leasing the property for cattle grazing, selling fresh water for oilfield operations (groundwater is tied to surface estate in TX), or building commercial facilities (man camp, RV parks, etc) depending on accessibility.
