What Is the Biggest Red Flag in a Home Inspection? A Guide for Homebuyers

Nicolas Atchison • January 5, 2025

Buying a home is one of the most significant investments you’ll ever make, and a home inspection plays a critical role in ensuring that investment is sound. During this process, inspectors evaluate the condition of the property and identify potential issues. While many findings are minor or easily fixable, some red flags can indicate serious problems that could affect your decision to purchase the home.


So, what is the biggest red flag in a home inspection? While the answer may vary depending on the home’s unique circumstances, structural issues are often considered the most concerning. Let’s explore why structural problems top the list, other potential red flags to watch for, and how to handle them if they arise.

Why Structural Issues Are the Biggest Red Flag

The foundation and structural components of a home are essential to its stability and safety. Issues such as cracks in the foundation, sagging floors, or compromised support beams can indicate significant underlying problems. These are not only costly to repair but can also make the home unsafe for living.


Common Structural Red Flags:

  1. Foundation Cracks: Large or uneven cracks may signal shifting or settling that could lead to severe structural damage.
  2. Sagging or Bowing Walls: This can indicate compromised structural integrity due to water damage, poor construction, or foundation issues.
  3. Uneven Floors: Floors that slope or feel unstable may point to problems with the foundation or support beams.
  4. Sticking Doors and Windows: Difficulty opening or closing doors and windows could be a sign of foundation movement.


Other Significant Red Flags in a Home Inspection

While structural issues are a top concern, other significant problems can also raise red flags during a home inspection:

Roof Damage

  • A damaged or aging roof can lead to leaks, water damage, and costly repairs. Look for missing shingles, sagging areas, or signs of water intrusion in the attic.

Electrical Problems

  • Outdated or faulty wiring is a serious safety hazard that can lead to fires. Signs to watch for include aluminum wiring, overloaded panels, or amateur electrical work.

Plumbing Issues

  • Leaking pipes, low water pressure, or signs of water damage can indicate underlying plumbing problems. Sewer line issues, in particular, can be very expensive to repair.

HVAC System Concerns

  • An old or poorly maintained heating, ventilation, and air conditioning (HVAC) system can lead to inefficient operation, higher energy costs, and eventual replacement expenses.

Water Damage and Mold

  • Signs of water damage, such as stains, odors, or visible mold, can indicate ongoing moisture issues. Mold not only damages the property but also poses health risks.

Pest Infestations

  • Evidence of termites or rodents can indicate damage to the structure or insulation of the home. Pest problems often require immediate attention and mitigation.


What to Do If a Red Flag Is Identified

If your home inspector identifies a major issue, don’t panic. Here’s how to handle it:

  1. Request Further Evaluation: Hire a specialist, such as a structural engineer or roofer, to assess the extent of the problem and provide repair estimates.
  2. Negotiate with the Seller: Use the inspection report as leverage to ask for repairs, a price reduction, or credits to address the issue.
  3. Consider the Long-Term Costs: Evaluate whether the home is still a good investment after factoring in the cost of repairs.
  4. Walk Away If Necessary: If the red flag is too significant and the seller isn’t willing to accommodate, it might be best to look for another property.

When most people think of home inspections, they picture traditional site-built houses. But what about mobile homes or manufactured homes ? These types of properties are often overlooked when it comes to thorough inspections—and that’s a big mistake. At Local Pro Home Inspection , we specialize in inspecting all types of homes, including mobile and manufactured homes throughout Sonoma County and beyond. Whether you're a first-time buyer, a seasoned homeowner, or a real estate professional, here's why a mobile home inspection isn't just a good idea—it's essential. What’s the Difference Between Mobile and Manufactured Homes? Before diving into the inspection process, let’s clear something up: Mobile homes typically refer to homes built before June 15, 1976 , before the federal HUD code was implemented. Manufactured homes are built after that date and must meet HUD standards for construction, safety, and energy efficiency. Both types are built in a factory and transported to the home site, which creates unique structural and mechanical challenges that aren't present in site-built homes. Why a Mobile or Manufactured Home Inspection Matters You might be thinking, “It’s a smaller home… do I really need an inspection?” Short answer: YES! Manufactured homes can be just as complex—and in some cases, more complex—than traditional homes due to their construction methods and the way they're installed on-site. Here are some common issues we find during inspections: Improper tie-downs or anchoring – Vital for safety, especially in areas prone to high winds or seismic activity. Roof damage or leaks – Flat or slightly pitched roofs on many mobile homes can be leak-prone over time. Faulty electrical systems – Especially in older models that may not meet modern electrical safety codes. Plumbing issues – From outdated materials like polybutylene to poor drainage and hidden leaks. Foundation & skirting problems – Including soft spots, shifting piers, or moisture buildup in the crawl space. HVAC inefficiencies or hazards – Improperly installed or aging systems that can be unsafe or inefficient. Unpermitted modifications – DIY renovations can lead to serious safety concerns if not done to code. What’s Included in a Mobile Home Inspection? At Local Pro Home Inspection , we treat manufactured homes with the same level of care and detail as any other structure. Here’s what you can expect from our inspection: Structural Evaluation We check for shifting piers, cracks, moisture intrusion, and signs of deterioration in the support system or skirting. Electrical & Plumbing Systems We test outlets, check for proper grounding, inspect breaker panels, and evaluate plumbing lines for leaks, water pressure, and material type. Roof, Siding & Exterior Our inspection includes roof condition, gutter systems, siding, windows, doors, and decks or stairs attached to the home. Interior & Appliances We test built-in appliances, windows, doors, ceilings, floors, walls, and ventilation to ensure everything is functioning as it should. Crawlspace or Undercarriage One of the most important parts of a manufactured home inspection, we evaluate what’s going on underneath—where many problems like moisture, insulation damage, and pest issues can hide. Why Lenders Often Require Mobile Home Inspections If you're financing a manufactured home purchase, many lenders will require a home inspection or even a HUD foundation certification to verify that the home meets certain safety standards. Skipping the inspection could mean delays in closing—or worse, unexpected costs down the road. We work with buyers, sellers, and agents to make the inspection process smooth and transparent so you can move forward with confidence. Why Choose Local Pro for Mobile & Manufactured Home Inspections? We’ve inspected homes in parks, on private land, single-wides, double-wides, and everything in between .

Final Thoughts: Don’t Skip the Inspection Mobile and manufactured homes offer a great path to affordable homeownership, but they come with their own set of risks and quirks. A professional home inspection gives you the peace of mind you need to move forward confidently. Whether you’re buying, selling, or just want to understand the condition of your home, Local Pro Home Inspection is here to help. 📞 Ready to Schedule Your Inspection?
