We compiled real rate data from Nashville PI firms, Tennessee marketplace platforms, and national cost benchmarks to build the most complete pricing reference available for hiring a PI in the Nashville area. Every number below is sourced and current as of early 2026.
1 How Much Do Nashville PIs Charge Per Hour?
Nashville private investigators charge $65–$150 per hour for most services in 2026. The Tennessee statewide range is $65–$125/hr, while budget-conscious options on Thumbtack start at $60–$70/hr. Specialized team operations can reach $225/hr.
| SERVICE LEVEL | HOURLY RATE | SOURCE |
|---|---|---|
| Budget / Thumbtack Nashville | $60–$70 | Thumbtack (2026) |
| Tennessee typical range | $65–$125 | Premier Protection & Investigations |
| Nashville single investigator | $145 | Gene Phillips Inc. |
| Second investigator (surveillance) | $65 | Gene Phillips Inc. |
| Special Ops team (3 operatives) | $225 | Gene Phillips Inc. |
| National average (2026) | $85–$225 | Salazar Investigations |
The wide range reflects both investigator experience and service complexity. A straightforward database lookup might bill at the lower end, while active surveillance with specialized equipment commands premium rates. Tennessee’s relatively low cost of living keeps Nashville PI rates 15–30% below major coastal cities, where rates regularly exceed $150/hr.
2 What Does Each Type of Investigation Cost?
Costs vary dramatically by service type. A basic background check starts at $100, while a complex custody investigation can exceed $8,000. Here’s what Nashville-area consumers should expect to pay for the most common PI services in 2026.
| INVESTIGATION TYPE | TYPICAL COST | SOURCE |
|---|---|---|
| Background check (basic) | $100–$500 | NowPI, Axeligence, Talo |
| Background check (comprehensive) | $500–$1,500 | NowPI, Axeligence |
| Full US background (Nashville firm) | $250/name | Gene Phillips Inc. |
| Skip trace / debtor locate | $600–$1,200 | The Dillon Agency (Nashville) |
| Missing person locate | $500–$2,500 | The Dillon Agency (Nashville) |
| Infidelity / domestic | $1,500–$5,000 | Salazar, NowPI, Axeligence |
| Surveillance (full day) | $600–$1,600 | Axeligence, Talo, Bark.com |
| Child custody investigation | $3,000–$8,000 | NowPI |
| Process serving | $75–$250/attempt | NowPI, Talo |
| Social media research (Nashville) | $85/name | Gene Phillips Inc. |
| Current address research (Nashville) | $75/name | Gene Phillips Inc. |
Infidelity and custody cases top the cost chart because they require the most surveillance hours. A standard infidelity case typically involves 15–30 hours of observation across multiple sessions, each billed at the investigator’s hourly rate plus expenses. Custody investigations are costlier still because they often combine surveillance with background research, witness interviews, and documentation suitable for Tennessee family court.
3 Nashville PI Rates Are 15–30% Below the National Average
The South Atlantic region (which includes Tennessee) averages $75/hr for PI services, compared to $105/hr nationally and $125–$135/hr in the Northeast and Pacific regions. Nashville’s lower cost of living directly translates to lower PI rates.
| REGION | AVERAGE RATE | RANGE |
|---|---|---|
| Nashville / Tennessee | $65–$125 | $60–$150 |
| South Atlantic (incl. TN) | $75 | $68–$125 |
| East North Central | $68 | $55–$200 |
| West South Central | $93 | $75–$110 |
| Pacific | $125 | $90–$175 |
| Middle Atlantic | $125 | $55–$150 |
| New England | $135 | $100–$175 |
| National average | $105 | $50–$225 |
The regional advantage doesn’t mean Nashville PIs are less capable — many firms here are staffed by former FBI agents, retired law enforcement, and military veterans with the same skill sets as coastal investigators. The rate difference reflects Tennessee’s lower overhead, not lower quality. When evaluating a Nashville PI, focus on licensing, experience, and case specialization rather than just the hourly number.
4 Retainers, Flat Fees, and the Costs Nobody Mentions
Beyond the hourly rate, expect a $1,500–$5,000 retainer upfront plus mileage ($0.55–$0.85/mile), vehicle rental ($85/day), and potential court testimony fees ($150–$500/appearance). Always get a written fee agreement before work begins.
| ADDITIONAL COST | TYPICAL AMOUNT | SOURCE |
|---|---|---|
| Retainer (standard cases) | $1,500–$5,000 | Salazar, NowPI |
| Retainer (complex cases) | $5,000–$10,000 | NowPI, Axeligence |
| Mileage reimbursement | $0.55–$0.85/mile | NowPI, Axeligence, Talo |
| Vehicle rental (Nashville) | $85/day | Gene Phillips Inc. |
| Court testimony | $150–$500/appearance | Salazar Investigations |
| Rush / weekend premium | 25–50% surcharge | Axeligence |
The retainer model is standard across Nashville PI firms. Gene Phillips Inc. requires individual clients to establish a “dollar authority” — a pre-approved spending cap — before any work begins, with invoicing against that cap. This gives you cost control, but it means you should budget for the retainer before your first consultation. If the retainer isn’t fully used, reputable firms refund the balance.
Three expenses consistently surprise first-time PI clients: mileage charges on surveillance that covers a large geographic area, vehicle rental when the investigator needs an unfamiliar car to avoid detection, and court testimony fees if the case goes to trial. Ask about all three during your initial consultation.
5 How Much Does It Cost to Find Someone in Nashville?
Locating a person through a Nashville PI ranges from $300 for a basic search to $5,000+ for complex multi-state cases. The Dillon Agency, a Nashville firm, published detailed tier pricing for locate services in November 2025.
| SERVICE | COST | TIMELINE |
|---|---|---|
| Basic locate search | $300–$800 | 1–3 days |
| Skip tracing / debtor location | $600–$1,200 | 3–7 days |
| Missing person (active case) | $1,000–$2,500 | 1–3 weeks |
| Complex / multi-state search | $2,000–$5,000+ | 2–4 weeks |
The Dillon Agency notes that the total cost depends on four factors: case complexity, how much information you can provide upfront, time sensitivity (rush cases cost more), and scope of the investigation. If you can give the PI a last known address, phone number, or social media profile, you’ll save significant hours — and money — on the locate.
For skip tracing specifically, Nashville PIs often work with attorneys on debt collection and civil litigation matters. The 3–7 day turnaround and $600–$1,200 price point makes PI skip tracing competitive with commercial skip-trace services, especially for cases where public databases have come up empty.
