Four-Point Inspection Explained: What You Need to Know

Whether looking to buy a new home, preparing to sell your home, or navigating real estate and property management professionally, you’re bound to stumble upon the term “four-point inspection.” Sounds quite technical, doesn’t it? What is a four-point inspection, anyway? In this article, we’ll cover everything you need to know and more.

Understanding the Basics of a Four-Point Inspection

At its core, a four-point inspection is a specialized examination of four essential components of a residential property. These include the roof, electrical and plumbing systems, and HVAC (heating, ventilation, and air conditioning) system. The inspection aims to provide an overview of these critical areas and assess their condition, functionality, and safety. The job is usually done by licensed professionals, like home inspectors or engineers (the detectives of the home inspection world).

While some of this maintenance and repair work can land on the pricier side, it’s crucial to have a solid understanding of the fundamentals (including realistic checklists and repair costs associated with the crucial home systems).

Breaking Down the Average Maintenance and Repair Costs

Roofing: The roof is a home’s first line of defense against weather elements. Regular inspections can help catch issues like leaks, missing shingles, or other damage that might lead to costly repairs if ignored. On average, minor roof repairs can range from $300 to $1,000, while more significant repairs or a roof replacement can cost anywhere from $5,000 to $10,000 or more, depending on the size and material of the roof.

HVAC Systems: Regular maintenance of your HVAC system can help ensure it operates efficiently year-round, providing a comfortable living environment. The average cost for HVAC maintenance is around $70 to $100 for a professional tune-up, while repairs can range from $150 to $2,000 depending on the severity of the issue. Replacing an HVAC system can cost between $4,000 and $12,000.

Electrical: Electrical systems are the backbone of modern homes, powering appliances, lighting, and more. Minor electrical repairs, like fixing a circuit breaker or updating outlets, can range from $100 to $500, while more extensive repairs or rewiring can cost between $500 to $4,000.

Plumbing: A well-functioning plumbing system is essential for supplying water and disposing of waste safely. Minor plumbing repairs like fixing a leaky faucet or unclogging a drain can cost between $50 to $450. More significant repairs like replacing pipes or fixing a sewer line can range from $500 to $4,000.

Importance of a Four-Point Inspection for Home Buyers and Sellers

For home buyers and sellers, a four-point inspection offers valuable insights into the condition of key systems within a property. This knowledge can help buyers make informed decisions and negotiate the terms of the transaction. Sellers, on the flip side, can address any little hiccups discovered during the inspection before listing their property. Doing this can polish appeal, potentially bolstering the market value and smoothing the path to a successful sale.

Relevance for Real Estate Agents, Insurance Professionals, and Property Managers

Real estate agents have a crucial role in guiding clients through the whirlwind of buying or selling a home. Knowing the condition of integral systems allows agents to accurately represent the property and manage client expectations. Insurance professionals benefit from a four-point inspection as it helps determine the insurability of a property. This can also illuminate any potential risks and appropriate coverage options. Property managers can use the findings of a four-point inspection to prioritize maintenance and ensure the safety and functionality of rental properties.

The Four-Point Inspection Process

During a four-point inspection, a licensed professional will thoroughly examine the roof, electrical and plumbing systems, and HVAC system. They will check for signs of wear and tear, damage, outdated components, code compliance, and any potential safety hazards. The inspector may also assess the age and condition of these systems to determine their remaining lifespan and functionality.

It’s important to note that a four-point inspection is not as comprehensive as a full home inspection. It focuses solely on the four designated areas, unlike a general home inspection that covers a broader range of aspects including structural integrity, pest inspections, and more.

Other Recommended Maintenance

Beyond the essential examination conducted during a four-point inspection, it’s prudent to consider other maintenance tasks to ensure a home is in tip-top shape. It’s advisable to perform regular checks on the foundation, windows, doors, and the exterior paint or siding for any signs of damage or wear. Here are a few suggestions for keeping things under control between inspections:

Window and Door Sealant: A high-quality window and door sealant can mend any leaks or gaps, ensuring better insulation and energy efficiency.

Extendable Gutter Cleaning Tool: Keep your gutters debris-free with an extendable gutter cleaning tool. It’s a safer and more convenient way to clean out gutters without needing a ladder.

Exterior Paint and Primer: When it’s time to touch up or repaint your home’s exterior, opt for a premium exterior paint and primer that can withstand weather elements and resist fading and peeling.

Additionally, scheduling routine pest inspections, cleaning gutters, checking the insulation, and testing the functionality of smoke and carbon monoxide detectors are also vital. Regular maintenance keeps a home safe and comfortable and helps avert expensive repairs down the line.

When to Call a Professional

While some minor maintenance tasks can be handled independently, there are instances when calling in a professional is necessary. Electrical issues, significant plumbing problems, roof repairs, and HVAC system malfunctions typically require professional expertise.


Furthermore, if you’re unsure about the condition of any systems within your home, scheduling a professional inspection is a smart decision. It’s always better to address potential issues sooner rather than later, and professionals have the knowledge and tools to identify and fix problems efficiently and safely.


Understanding the importance and the scope of a four-point inspection is crucial for anyone involved in the real estate sector. This applies whether you’re buying, selling, or managing properties. It provides a snapshot of a property’s condition, focusing on four critical systems. Moreover, being cognizant of other necessary maintenance tasks and knowing when to call a professional is integral to maintaining a property’s value. Not to mention ensuring safety and functionality. By staying proactive in these areas, you can navigate the real estate landscape with a more informed perspective and make better decisions regarding property transactions and upkeep.
