Home Inspection Red Flags

Real Estate

In a real estate transaction, the home inspection is the last big step before you make your final negotiations to close the deal. You can see the finish line, but there is still some work to do before taking a victory lap.


Most things that come up on inspection reports are common, manageable, and leave room for additional negotiations. However, as a seasoned realtor, there are a few major red flags I look out for to help guide my clients to make informed decisions.


Crawl Space Issues

There are specific crawl space issues that are red flags if they show up on a home inspection report. High moisture levels within the crawl space are a big concern, as they can lead to mold growth, wood rot, and attract pests. Inspectors may identify water damage, indicating potential leaks or inadequate drainage systems. Structural issues such as sagging or uneven floors could also indicate problems within the crawl space, such as compromised support beams or improper foundation construction. Poor ventilation can contribute to moisture-related problems and compromise air quality, while the presence of pests or pest damage may suggest a need for pest control measures.

A Bad Roof

It's no secret that replacing a roof is a significant investment, so many potential buyers have questions about the roof’s condition. The roof needs to be structurally sound. If it hasn't been replaced in more than 20 years or shows serious signs of damage, proceed with caution. Aside from the expense, a compromised roof may lead to costly repairs and potential water damage, making it a crucial aspect to scrutinize during the inspection process.

Structural Problems

This one is the biggest red flag of them all! A solid structure is the backbone of a home, and any issues in this department can have far- reaching consequences. Not only do structural problems jeopardize the safety of the home, but they can cost tens of thousands of dollars to repair. A cracked foundation or a load-bearing wall that's in bad condition can signify signs of something serious. Also, keep an eye out for cracks in the basement floor or the home's exterior that are larger than half an inch. Misaligned door frames, windows, slanted front steps, and misaligned doors and windows can also be signs of structural issues.

HVAC Concerns 

During a home inspection, various HVAC (Heating, Ventilation, and Air Conditioning) issues can also be expensive red flags for prospective buyers. Outdated HVAC systems may be flagged for potential replacement or significant repairs, impacting both comfort and energy efficiency. Additionally, ductwork problems, such as leaks or poor insulation, can increase energy bills and compromise indoor air quality. Inadequate maintenance or dirty filters may signal a lack of proper care, potentially leading to reduced system lifespan and performance issues. Unusual sounds or odors during the inspection may indicate underlying problems with the furnace, air conditioner, or ventilation components.

Windows (Broken Seal)

Broken seals on windows can be a significant red flag during a home inspection, as they often indicate potential issues with insulation and energy efficiency. Window seals are responsible for keeping out moisture and preventing air leaks, contributing to the overall thermal performance of a home.

When seals break or fail, it can lead to moisture infiltration, causing water damage, mold growth, and compromised indoor air quality. Additionally, broken seals allow for the escape of conditioned air, leading to decreased energy efficiency and increased utility costs. During an inspection, inspectors may identify fogging or condensation between window panes as a clear sign of a broken seal.

Cupping Floors

Cupping floors are the final red flag to watch out for on a home inspection report. Cupping occurs when the edges of floorboards become higher than the center, creating a concave shape. This is often associated with excessive moisture absorption, leading to wood expansion and warping. In a home inspection report, cupped floors may indicate water damage from leaks, poor ventilation, or high humidity levels. Moisture-related issues not only compromise the aesthetic appeal of the flooring but can also lead to more severe problems, such as mold growth and structural instability. Addressing the underlying causes of cupping is crucial to prevent further damage and maintain the integrity of the home's foundation and flooring system.


Don’t Panic! Massive Red Flags Are Rare

A comprehensive home inspection is a critical step in the home-buying process that offers buyers valuable insights into the property's condition. With over 20+ years of experience , not all of the red flags on this list are deal-breakers. Sometimes, these issues can be easily fixed for a great price, and, on rare occasions, they are enough to make the deal fall through.
