Buying a Home With Well and Septic in Tennessee

Most homes in the busier parts of Middle Tennessee connect to public water and sewer. Plenty of others, especially as you move away from city centers, do not. If you are looking at a property with a private well and a septic system, the buying process has a few extra steps.

None of them are complicated, but they take time and they should be planned for early. Here is how I walk buyers through it.

Why a well and septic system change the process

With public utilities, a city or utility district maintains the system and you pay a monthly bill. With a well and septic system, the equipment is on the property and the upkeep is the owner’s responsibility.

That means two more systems to understand before you commit. A standard home inspection usually does not go deep on either one, so you will likely want separate evaluations. Your inspector or the relevant specialists can tell you what falls inside their scope.

Also, whether a home is on public sewer or septic depends on the exact address. Two houses on the same road can be set up differently. Confirm it for each property rather than assuming.

Septic systems: what to ask and what to check

Start with the seller’s paperwork. In Tennessee, sellers complete the residential property condition disclosure, or file an exemption. Read it carefully for anything about the septic system, past repairs or drainage problems. It is a starting point, not a replacement for your own inspection.

Then consider a dedicated septic inspection. Common questions include:

• Where are the tank and the drain field, and are they accessible?
• What condition is the tank in?
• Are there signs of backup, standing water or slow drains?
• Is there a record of pumping or repairs?

A sewer scope, which is a common add-on for homes on public sewer, does not take the place of a septic evaluation. They address different systems.

You may also hear the term perk test, which is a soil evaluation tied to how well the ground absorbs water. It comes up most with vacant land or new construction, and sometimes when a system’s capacity is in question. Septic rules and who handles permits and records can vary by county, so ask the local office that covers the address what is on file. I am happy to help you figure out who to call, but I cannot tell you what a given system will or will not pass.

Well water: testing before you commit

With a private well, there is no utility testing the water for you. Well water testing during a home purchase is how you learn what is actually coming out of the tap.

A few practical points:

• Hire a qualified professional or lab to collect and test the sample, and ask what the test covers.
• Ask about the well’s age, depth and pump, and whether the seller has maintenance records.
• Ask how much water the system produces, since flow can matter as much as quality.
• Read the results with the person who ran the test. If something is flagged, ask what treatment or repair involves and what it costs.

Radon testing is a common add-on to a standard inspection. The EPA’s radon information is a good place to read up on how testing works and what the results mean, and you can talk with your inspector about whether it makes sense for the home.

I do not recommend specific inspectors or labs. Ask for licensed or certified professionals, and compare more than one.

Check the location, the county and the paperwork

County lines matter here. Spring Hill, for example, includes parts of both Williamson and Maury counties, so services, schools and taxes can differ by address. Murfreesboro is in Rutherford County and Columbia is in Maury County, and neither is in Williamson County. If you are shopping across several towns, the office you call for septic records may change.

For any home you are serious about:

• Look up the parcel on the Williamson County property search or the equivalent for the county it sits in.
• Confirm with the local government whether public sewer is available at the address. The City of Spring Hill site is one starting point for that area.
• Verify school assignment with the school district and property taxes with the county. Both depend on the exact address.

The termite and wood-destroying organism (WDO) inspection is also commonly requested by buyers and lenders in Tennessee, so plan for it alongside the well and septic work.

Fit it into your timeline and budget

Each extra inspection adds scheduling. Septic and well evaluations may need separate appointments, and lab results take time. If you are working against an inspection deadline in your contract, ask your agent to line these up as soon as your offer is accepted.

Budget for them too. Closing costs typically run 2 to 4 percent of the purchase price, plus earnest money and moving costs, and specialty inspections come on top of that. If a test turns up a problem, repair or treatment costs are a negotiation point, and your agent can help you think through your options.

As for the wider market, here is a recent snapshot. In Spring Hill, the median sale price was $508,284 as of 2026-08-31, down 4.1% from a year earlier, with 4.1 months of supply (Redfin, rolling 3 months). Months of supply of 4 to 6 is generally considered balanced. The 30-year fixed mortgage rate was 7.28% for the week of 2026-10-01 (Freddie Mac via FRED). These numbers describe past activity, not what will happen next, and they will not tell you anything about an individual property.

If you are financing, ask your lender whether they have any requirements related to private wells or septic systems, and get that answer early. The CFPB Owning a Home guides explain the loan process in plain language. You can also run payment scenarios with the mortgage calculator, and look at the market data for the I-65 corridor to compare towns.

Next steps

A well and septic home is not a reason to skip a property, and it is not a reason to rush. It just means a few more questions and a few more appointments.
