When people in Franklin start looking for a private investigator in Franklin, TN, the first question is usually the same: "How much will this actually cost me?" It's a fair one, because no one wants surprises when emotions and money are both on the line. Whether you're facing a child custody case or trying to confirm infidelity suspicions, understanding how private investigator services in Franklin, TN are priced helps you set realistic expectations and invest wisely in getting the truth.


How Much Does It Cost to Hire a Private Investigator in Tennessee?


In Tennessee, private investigators in Franklin, TN typically charge between $75 and $150 per hour, depending on the investigator's experience, the complexity of the case, and the technology involved (like GPS tracking or specialized surveillance equipment). Many reputable agencies offering private investigator services in Franklin, TN, including The Dillon Agency, may request a retainer between $1,500 and $2,500 to begin work. Simple background checks or address verifications can be billed as flat rate services ($100–$300), while complex surveillance cases, such as infidelity or child custody investigations, can range from $400 to over $1,000 in total.


These fees reflect not only hours in the field but also legal compliance, report preparation, video documentation, and testimony if needed in court.


The Local View: Why Costs for a Private Investigator in Franklin, Tennessee Vary


Franklin isn't Nashville... but our cases often spill over there. That means a private investigator in Franklin, Tennessee handles a mix of suburban discretion and metro level complexity. If your case involves multiple locations (say, a spouse who works in Nashville but lives in Williamson County), that travel time factors into your hourly cost. Fuel prices, mileage, and surveillance time all add up... but so does the peace of mind of having a licensed Tennessee private investigator handling your case legally and discreetly.


Think of hiring a private investigator in Tennessee like hiring an attorney or mechanic: you're paying for experience, equipment, and accuracy. In smaller towns, you might find "discount PIs," but that discount can cost more later if evidence isn't collected properly or doesn't hold up in court.
