Who Pays for a Perc Test? Buyer vs. Seller Responsibility

Written by John Kakanis | Jun 27, 2025 11:15:00 AM

Learn who typically pays for a perc test when selling land in Florida and how it can impact your land sale. Know what to expect and how UNITY simplifies the process.

Who Pays for a Perc Test—Buyer or Seller?

It Depends on the Deal Structure

There’s no hard rule that says either party must pay. Instead, it depends on the type of transaction and the expectations set between buyer and seller.

Let’s break down the most common scenarios:

1. Traditional Land Sales (With a Realtor)

In a standard listing situation, the buyer typically pays for the perc test as part of their due diligence before closing. They often want to confirm the land is buildable before proceeding.

2. Investor or Direct Buyer Transactions

In cases where a landowner sells directly to an investor (like UNITY), the buyer may cover the cost—but only after an initial agreement is in place. UNITY, for example, handles due diligence and may pay for testing if we decide to move forward with the deal.

Tip: If you’re working with a direct buyer, always confirm whether they intend to do a perc test and who will cover the cost. Some buyers may cancel their offer if a test fails.

3. Seller-Initiated Testing (To Increase Market Value)

In some cases, sellers may choose to do a perc test ahead of listing to make the land more attractive or justify a higher asking price. This gives potential buyers peace of mind and can make your lot stand out.

Should You Perc Test Your Land Before Selling?

It depends on your timeline and goals.

You might want to order a perc test yourself if:

  • You’re selling in a competitive market

  • You want to increase the asking price

  • You’ve had buyers back out due to unknown septic potential

However, testing can cost between $300 and $1,000 depending on the county and the complexity of the site. It’s not always necessary—especially if the buyer is doing their own due diligence.

How UNITY Handles Perc Testing?

At UNITY, you won’t need to arrange your own perc test. If we move forward with an offer on your property, we handle the due diligence, including testing if needed. We’ll review soil maps, prior records, and—when necessary—order testing through our local partners.

That said, if a perc test fails or indicates the land isn’t suitable for a septic system, it may affect the final offer—or halt the purchase altogether.

This is why we always review environmental and utility factors before closing. Our goal is to give you a fair, informed offer based on your land’s actual usability.

What to Know Before Moving Forward

Whether you’re a buyer or a seller, here are some helpful tips:

  • Check with your local health department to see if perc testing is required in your area.

  • Ask your buyer (or their agent) if they plan to do a test before closing.

  • Don’t commit to testing unless necessary. In many direct sale situations, it’s better to wait until there’s a serious buyer.

  • If you’re unsure, reach out. UNITY’s team can help you understand if testing is likely to come up based on your parcel and county.

FAQs

Q: Do I need a perc test before selling land?
A: Not always. If the buyer is doing their own due diligence, they may handle it. However, a perc test can help you market your land as buildable.

Q: How much does a perc test cost in Florida?
A: Costs range from $300 to $1,000 depending on the location, size of the property, and type of testing required.

Q: Will UNITY pay for the perc test?
A: If we’re buying your land and decide to proceed, we’ll handle due diligence—including testing if necessary—as part of our evaluation process.

Q: What happens if the land fails the perc test?
A: If your land doesn’t pass, it may not be eligible for a septic system. This could lower its value or make it harder to sell for residential use.

Q: Can I sell land that fails a perc test?
A: Yes, but it may be sold for non-residential use or require alternative septic solutions. UNITY can still evaluate your land and provide an honest offer based on its condition.
