A 4-point inspection is a limited insurance underwriting inspection covering exactly four systems: roof, electrical, plumbing, and HVAC. Florida insurance carriers commonly require one before binding or renewing a policy on a home once it reaches a certain age, most often somewhere between 20 and 40 years old depending on the carrier, with 30 to 40 years being the most common threshold and some carriers, including Citizens Property Insurance Corporation, starting as early as 20 years. There's no Florida law that mandates it; it's an insurance-company requirement, and it exists because older homes carry a materially higher risk of roof failure, outdated wiring, aging galvanized or polybutylene plumbing, and worn-out HVAC systems. Unlike a full home inspection, a 4-point doesn't grade cosmetic condition or every system in the house, it's a narrow pass-or-fail risk check that an insurer uses to decide whether to write the policy at all, and a failing report can genuinely stop a sale if the buyer can't get insurance bound.

- Florida law doesn't require a 4-point inspection. It's an insurance carrier requirement, and it typically kicks in once a home reaches somewhere between 20 and 40 years old, with 30 to 40 years being the most common threshold and Citizens often starting closer to 20.
- It exists because older homes carry more risk of aging roofs, outdated or unsafe wiring (like knob-and-tube or aluminum branch wiring), old galvanized or polybutylene plumbing, and worn HVAC systems, all of which drive claims.
- A 4-point inspection is narrower and cheaper than a full home inspection, typically $75 to $150, and it's usually ordered specifically because a carrier requires it, not out of general curiosity about the home's condition.
- A failing 4-point report can genuinely kill a deal. If a carrier won't bind a policy on the home as-is, a buyer using financing usually can't close, since a lender requires proof of insurance before funding.
What is a 4-point inspection?
A 4-point inspection is a limited, insurance-focused inspection that looks at exactly four systems in a home: the roof, the electrical system, the plumbing system, and the HVAC (heating, ventilation, and air conditioning) system. It's performed by a licensed home inspector, contractor, or in some cases the insurer's own inspector, and the results go on a standardized form that the insurance company uses to decide whether it's willing to write, renew, or continue a policy on the home. Unlike a general home inspection, a 4-point isn't trying to catalog every issue in the house. It's answering one specific question for the insurer: is this home's core risk profile acceptable to insure as-is?
Why Florida insurers require this on older homes
There's no Florida statute that mandates a 4-point inspection. This is entirely a carrier-driven underwriting requirement, but it's an extremely common one. Most insurance companies start requiring a 4-point inspection somewhere in the 30 to 40 year age range for a home, and that threshold is the most typical benchmark cited across Florida carriers. Some carriers set the bar lower, and Citizens Property Insurance Corporation, the state's insurer of last resort, is often cited as requiring one closer to 20 years old. The exact cutoff varies by company, but the pattern is consistent: the older a home gets, the more likely a carrier is to want documented proof of its core systems before agreeing to insure it.
The reasoning is straightforward risk management. Roofs wear out and become more likely to leak or fail in a storm as they age. Older homes may still have electrical systems that were acceptable when built but are now considered unsafe or obsolete, including aluminum branch wiring, knob-and-tube wiring, or federal pacific panels that carriers specifically flag. Plumbing installed decades ago may be galvanized steel or, in some homes built in a certain era, polybutylene, both of which are prone to corrosion, leaks, and the kind of water damage claims insurers actively try to avoid. And an HVAC system nearing or past its expected lifespan is more likely to fail and, in some cases, contribute to water damage from a failed condensate line. None of these are hypothetical concerns for an insurer, they're exactly the categories that generate real claims, and the 4-point inspection is how a carrier gets ahead of that risk before writing the check.
How a 4-point differs from a full home inspection
A full home inspection, the kind most buyers order during their due diligence period, is comprehensive. It looks at structural elements, appliances, windows, doors, drainage, attic, crawl space, and dozens of smaller items, and it's meant to give the buyer a complete picture of the home's condition so they can negotiate repairs or walk away if something serious turns up. A 4-point inspection is much narrower by design. It only reports on the roof, electrical, plumbing, and HVAC, and it's typically graded in simpler terms, essentially whether each system is in acceptable condition and roughly how much useful life it has left, rather than a detailed inventory of every observation. A 4-point is also usually cheaper, often in the same $75 to $150 range as a wind mitigation inspection, and faster to complete, since the inspector isn't examining the entire property. The two inspections serve different purposes and different audiences: the full inspection is for the buyer, the 4-point is for the insurer.
Why a failed 4-point inspection can actually kill a deal
This is the part every new agent needs to internalize, because it's where a 4-point inspection stops being a formality and starts being a real threat to a closing. If a home fails the 4-point, meaning the roof, electrical, plumbing, or HVAC system is flagged as high-risk or beyond acceptable condition, an insurance carrier may decline to write a policy on the home as-is. Some carriers will offer conditional approval if specific repairs are made and verified, such as replacing an outdated electrical panel or re-piping galvanized plumbing, but that takes time and money that isn't always built into the transaction timeline. If a buyer is financing the purchase, the lender requires proof of homeowners insurance before funding the loan, no exceptions. A buyer who can't get a policy bound, whether through a standard carrier or Citizens, simply can't close, no matter how much they want the home or how solid their financing otherwise looks. This is why an experienced agent treats an older home's age as a signal to raise the 4-point question early, ideally before an offer is even written, rather than letting it surface for the first time during underwriting with a closing date already on the calendar.
What a new agent should actually do with this
On any listing or any buyer's target property that's approaching or past 25 to 30 years old, it's worth asking directly whether a recent 4-point inspection exists, or flagging early that the buyer's insurance agent should run one as soon as possible after going under contract, not the week before closing. For a seller, having a current, passing 4-point report available up front, much like a wind mitigation report, removes uncertainty for a buyer and their lender and signals that the home's core systems have already been vetted. For a buyer's agent, making sure this gets ordered early, alongside the general home inspection, protects the client from discovering an insurance-killing problem only after they're deep into the transaction, emotionally and financially invested, and running out of time on their financing contingency.
What actually happens after a failing report
A failed 4-point inspection doesn't always mean the end of the road, but it does mean the clock starts running against the transaction timeline. Depending on what specifically flagged, a homeowner may be able to get conditional approval from a carrier by completing targeted repairs, such as replacing an outdated electrical panel, updating aluminum wiring at the connections most prone to overheating, re-piping galvanized or polybutylene plumbing, or replacing a roof that's too far past its expected service life. Each of those fixes takes real time and real money, and none of them happen instantly, which is exactly why discovering a 4-point problem late in a transaction is so damaging. A buyer who's already past their inspection contingency, with an appraisal ordered and a closing date on the calendar, has far less room to negotiate repairs, extend timelines, or walk away cleanly than a buyer who finds out during the first week under contract. Sellers of older homes are often better served getting ahead of this entirely, either by ordering their own 4-point inspection before listing or by being upfront about the home's roof and system ages so a buyer's agent can plan around it from the start.
