The Minnetonka Defect Library.
The defects that actually decide deals in the west metro — documented from the field, not a generic checklist.
The Minnetonka defect library documents the home defects we find most often locally — EIFS moisture, cedar shake, ice dams, Federal Pacific panels, aluminum wiring, polybutylene, and oak-wilt sewer-root intrusion — with causes, what we check, and why each matters.
