Inspection problems that derail NOVA transactions cluster around HVAC systems over 15 years old, roofs over 20 years old, evidence of water intrusion (especially basements), Federal Pacific or Zinsco electrical panels, and polybutylene plumbing in homes built 1978–1995. If your home has any of these, order a pre-inspection before listing. This eliminates surprises, lets you disclose intentionally rather than reactively, and prevents the appraisal-gap negotiations that kill deals under departure pressure.
