Realtors’ Guide to Selling a House With a Septic System

Serving King County WA

Many homes in King County WA rely on septic systems instead of city sewer connections. While they’re common and reliable when properly maintained, septics can raise questions for buyers and sellers who aren’t familiar with how they work.

In King County WA, septic inspections are required before a home sale can close. But selling a house with a septic system doesn’t have to be stressful.

Puget Sound Septic has helped realtors, buyers, and sellers navigate the septic inspection process. Knowing what to expect (and partnering with the right septic professionals) can help you close deals faster and keep everyone happy.

How to Alleviate Concerns for First-Time Buyers

As a realtor, you can help ease buyers’ worries by providing education and reassurance.

  • Start by explaining how septic systems work in simple terms. A septic system treats wastewater right on the property. Solids settle in the tank while liquids flow out to the drain field and are absorbed into the soil.
  • Emphasize the importance of the required inspection. Let buyers know that a professional will thoroughly check the system before they commit to the purchase.
  • Connect them with trusted local experts. When buyers know they have a reliable septic company to call for questions, maintenance, and future inspections, they can feel more confident about their purchase.

How to Promote a Property With a Septic System

Some realtors worry that having a septic system might make a property harder to sell. In reality, a well-maintained septic system can be a selling point, especially when you know how to present it.

  • Highlight the benefits of septic ownership. Unlike city sewer connections, septic systems don’t come with monthly sewer bills. Homeowners have more control over their wastewater management and aren’t affected by municipal sewer issues.
  • Showcase the home’s maintenance history. If the seller has kept records of regular pumping and inspections, share this information with potential buyers. A well-documented maintenance history shows that the system has been cared for and is less likely to have problems.
  • Get the inspection done early. By completing the septic inspection before listing the home, you can confidently tell buyers that the system is in good condition.

Why Realtors Should Get an Inspection Before Listing

Recommending a septic inspection before the home hits the market prevents surprises, builds buyer confidence, and saves time.

Finding out about a failing septic system during the closing process can derail a sale. Since real estate transactions move fast, waiting until the last minute for an inspection (and then scrambling to address any issues) can cause the deal to fall apart.

When you can show buyers a clean inspection upfront, it removes a major source of uncertainty.

Common Questions From Home Buyers

Is a septic system safe?

Absolutely. Septic systems have been used for decades and are a safe, effective way to manage household wastewater.

How do I know if the septic system is working properly?

By getting an inspection performed. A professional septic inspection checks the tank, drain field, and distribution box to make sure everything is functioning as it should.

What happens if the inspection finds a problem?

If issues are found, the seller is typically responsible for making repairs or negotiating with the buyer.

How often will I need to maintain the system?

Most septic systems need to be pumped every three to five years, depending on the size of the tank and household usage.

Common Questions From Home Sellers

Do I really need an inspection before selling?

Yes. In King County WA, septic inspections are required before a property can change hands. The inspection must be completed before closing, and the buyer must receive the full Time of Sale Inspection Report along with any comments from Public Health.

Who pays for the septic inspection?

In Washington state, the seller is responsible for paying for the septic inspection.

What if my system fails the inspection?

A failed inspection can delay or even cancel a sale. Depending on the issues found, you may need to repair or replace parts of the system to meet code requirements. You could also negotiate with the buyer to share repair costs or lower the sale price.

How long does a septic inspection take?

Most inspections take between 30 minutes and a few hours, depending on the size of the system and any issues that come up.
