For uppers, shimming can still be required, such as behind the steel support rail if the wall is horizontally wavy, or at the bottom of the cabinet if the plastic spacer they include isn't thick enough. 

Is that from a patio set? 

Inside solutions like French drains, sump pumps, or plastic inside waterproofing might be fine for that 25-year storm, but the water is already getting in and damaging the foundation.

It already has a concrete patio and is relatively private.

Only painted the interior of the big house, the small house for new wiring, central hvac, and a new kitchen which allowed the laundry to be inside instead of on the back patio.

I noticed most of my tenants had bbq grills but no patio furniture.

Major items in the renovation include:Level floors, Lay new peel and stick vinyl throughoutRemove wall heater from bedroomRe-sheetrock in living room to smooth out wall (tie control thermostat wires in wall to provide power on roof)Install new plumbing runs throughoutInstall new drain lines where applicableInstall water line and in-wall box for refrigerator ice makerInstall new tubInstall new tile shower surroundMove over all light switches away from door trimRun wire to two new living room lights, install three way switch outside of bedroom and exterior patio doorInstall new light and wall switch in bedroom closetMove bedroom door 6-7 inches to the south to allow construction of half wallDemo existing living room closet and construct half wall (replumb gas and electrical as required)Demo kitchen cabinets, pantry and counterInstall sheet-rock over water damaged hardboard in bathroom and bedroomsInterior Paint throughoutInstall new bathroom vanityInstall new bathroom lightInstall new kitchen lightInstall new cabinetsInstall new granite counter topsInstall new AC registers (bedroom and bathroom)Install new toiletInstall three (3) new six-panel doors (bedroom, closet, bathroom)Install new outlets and coversInstall new switches and coversAgain, my four estimates for this work range from $14,000 to 25,000 and would complete in 2-3 weeks.

Have them regrade and put rock/plastic around the foundation to shed water away.

From your first picture there is a plastic pane that slides into place so that it can stay closed/locked and keep the dog (or other animals) from climbing in and out.

Is the exterior basement wall covered in plastic wrap?
