From Offer to Closing: The Real Estate Agent’s Guide to Septic Systems

Septic systems may not be glamorous, but for properties without

municipal sewer service, they are critical infrastructure. As a real estate

agent, your understanding of septic systems can directly influence

property value assessments, buyer confidence, and the overall success of

a transaction.

This guide will walk you through everything—from the basics of septic

systems to handling inspections, documentation, repairs, and closing—

so you can navigate these transactions like a pro.

1. Understanding Septic Systems

Septic systems are self-contained wastewater treatment solutions,

essential for homes in areas without centralized sewer service. They

require proper design, installation, and maintenance to function

effectively.

Why it matters for agents:

You can better advise clients on property value and maintenance needs.

You’ll help prevent costly failures that could derail a deal.

You’ll guide buyers toward certified professionals for thorough

inspections.

Pumping vs. Inspection – Know the Difference:

Pumping removes sludge and is routine maintenance.

Inspection is a full evaluation of the system’s health, required for a

smooth transaction.
