1. Roof and Exterior Coverings

The roof is a mobile home's primary defense against the elements, making it a critical first stop on any comprehensive mobile home inspection checklist. Unlike traditional site-built homes, many mobile homes feature lower-pitched roofs with specific materials like metal panels or specialized membrane coatings. These systems require a keen eye to spot potential failures that could lead to catastrophic water damage and compromise the home's structural integrity. This inspection involves scrutinizing the entire roofing system, from the surface material and seams to the flashing around vents and skylights.

In West Tennessee, the combination of heavy rainfall, high humidity, and occasional severe storms puts immense stress on mobile home roofs. A common issue we see is rust-through on older metal roofs, particularly along seams or where fasteners have loosened. For shingled roofs, moss and algae growth can trap moisture, accelerating deterioration and leading to leaks that may not be immediately visible from inside. Ignoring these small signs can result in costly, widespread problems.

Actionable Inspection Tips

To properly assess the roof's condition, follow these steps:

• Systematic Visual Scan: During daylight hours, walk the perimeter of the home and look for obvious signs of damage such as missing shingles, dented metal panels, or sagging areas.
• Check Seams and Flashing: Pay close attention to the seals around vents, pipes, and the edges of the roof. This is where most leaks originate. Look for cracked sealant or gaps.
• Interior Water Signs: Inside the home, check ceilings and the corners of closets for water stains, discoloration, or peeling paint. These are tell-tale signs of a roof leak.
• Know the Lifespan: Ask about the roof's age. Most mobile home roofing materials have a lifespan of 15-25 years. If it’s nearing the end of its life, budget for a replacement.

Given the complexities and safety risks, a professional evaluation is often the wisest choice. You can explore a deeper dive into common roofing issues unveiled by home inspectors to better understand what a professional looks for. A small investment in a thorough roof inspection can save you thousands in future repairs.

2. Plumbing System and Water Lines

A functional plumbing system is essential for a home's livability, and in mobile homes, the system has unique characteristics that demand a thorough review. Unlike site-built homes with rigid copper or PVC pipes often housed within conditioned spaces, many mobile homes utilize flexible PEX or polybutylene tubing running through the underbelly. This design makes the plumbing more susceptible to freezing, physical damage, and deterioration, making it a crucial component of any mobile home inspection checklist. This inspection covers everything from the water supply lines and fixtures to the drain system and water heater.

In West Tennessee, while our winters are milder than in northern climates, unexpected cold snaps can still freeze unprotected pipes in the crawlspace, leading to bursts and significant water damage. Another common issue is the presence of older galvanized steel or polybutylene "Quest" pipes, which are known to degrade over time, causing low water pressure and a high risk of leaks. Identifying these materials early can prevent a future plumbing catastrophe and expensive repairs.

Actionable Inspection Tips

To properly evaluate the plumbing system's condition, follow these steps:

• Test Water Pressure and Drainage: Turn on all faucets and flush all toilets simultaneously. Note any significant drop in pressure, which could indicate undersized or clogged pipes. Check how quickly sinks and tubs drain.
• Inspect Under Sinks: Look in the cabinets under every sink for signs of past or present leaks, such as water stains, warped wood, or active drips. Ensure each drain has a proper P-trap to block sewer gases.
• Check the Water Heater: Look for signs of rust or leaking around the base of the water heater. Note its age (usually on the manufacturer's sticker) and test to ensure it produces adequately hot water.
• Verify Freeze Protection: Look at the underbelly to see if water lines are insulated or if heat tape has been installed. This is a critical preventive measure, even in our climate.
• Inquire About the Septic System: If the home isn't on a city sewer, ask for the septic system's maintenance records, including the date it was last pumped.

The complexities of mobile home plumbing, especially issues hidden in the underbelly, often require a professional eye. You can discover more about frequent plumbing issues found during inspections to understand what a professional looks for. A detailed plumbing evaluation is a non-negotiable step to ensure your new home is safe and sound.

3. Electrical System and Wiring

The electrical system is the nerve center of a mobile home, yet it often harbors hidden dangers that a standard visual check might miss. While manufactured homes follow standardized electrical codes like the NEC, their unique construction and the prevalence of older models in the market necessitate a specialized inspection. This part of the mobile home inspection checklist focuses on the main panel, wiring type, outlets, switches, and critical safety features like GFCIs. A faulty electrical system is not just an inconvenience; it's a significant fire hazard.

In West Tennessee, we frequently encounter older mobile homes with outdated and potentially hazardous electrical components. Homes built before the late 1970s may still contain aluminum wiring, which requires special connectors to be safe and is a known fire risk if improperly handled. Another common issue is "double-tapping," where two circuits are connected to a single breaker designed for one, creating an overload risk. These are critical findings that directly impact the safety and insurability of the property.

Actionable Inspection Tips

To properly evaluate the electrical system's safety and functionality, use this checklist:

• Test Outlets and GFCIs: Use a simple outlet tester to check every outlet for proper wiring and grounding. Press the "test" button on all Ground Fault Circuit Interrupter (GFCI) outlets, which should be in kitchens, bathrooms, and outdoor areas, to ensure they trip correctly.
• Inspect the Electrical Panel: Open the main panel and look for signs of trouble like discoloration, rust, a burning smell, or overcrowded wiring. Check for any breakers that are warm to the touch.
• Identify Wiring Type: If possible, safely identify the type of wiring. The presence of solid-strand aluminum wiring is a red flag that requires immediate professional assessment.
• Look for Amateur Work: Be wary of exposed wires, poorly secured outlets, or unconventional wiring setups. These often indicate unpermitted, DIY work that may not be up to code.

Due to the inherent risks, a detailed electrical inspection is best left to a professional. You can discover more about the common electrical problems found during home inspections to understand what a certified inspector looks for. A thorough evaluation ensures the home is safe for your family and prevents unexpected, costly repairs down the road.

4. HVAC System and Ventilation

The heating, ventilation, and air conditioning (HVAC) system is the heart of a mobile home's comfort, controlling temperature and air quality year-round. This part of the mobile home inspection checklist is crucial because these homes often utilize compact, self-contained units specifically designed for smaller spaces. Proper function and maintenance are essential for both efficiency and inhabitant health. An overworked or failing system can lead to high energy bills, poor air quality, and expensive, unexpected repairs.

In West Tennessee's climate, with its sweltering, humid summers and chilly winters, an HVAC system is a non-negotiable necessity. A common issue we encounter is deteriorated or disconnected ductwork running through the crawlspace, which causes significant efficiency loss and can introduce moisture and pests into the airflow. Another frequent problem is an undersized AC unit that struggles to keep up on hot days, running constantly without ever properly cooling the home.

Actionable Inspection Tips

To thoroughly evaluate the HVAC system, follow these key steps:

• Test Both Systems: Turn on the heat and the air conditioning separately (regardless of the season) to ensure both functions operate. Listen for unusual noises like grinding or squealing.
• Inspect Ductwork: If accessible, check the ductwork in the crawlspace for tears, crushed sections, or disconnected joints. Ensure it is adequately supported and insulated.
• Check the Age: Locate the manufacturer's label on the indoor and outdoor units to determine their age. Most mobile home furnaces last 15-20 years, while AC units last 10-15 years.
• Verify Airflow: Walk through the home and feel the airflow from each vent. Weak or non-existent airflow in certain areas can indicate a ductwork blockage or leak.
• Review Maintenance Records: Ask the seller for any service history. Regular professional maintenance is a strong indicator of a well-cared-for system and is essential for longevity.

5. Foundation and Structural Support System

Unlike traditional homes, a mobile home’s entire structural stability relies on a specialized foundation and support system. This undercarriage, consisting of a steel frame, piers, and tie-downs, is the unsung hero that keeps the home level, stable, and safe. A failure in this system can lead to severe issues, from sloping floors and binding doors to catastrophic structural collapse. A thorough inspection of the foundation is non-negotiable and a critical part of any mobile home inspection checklist.

In West Tennessee, the clay-rich and often moist soil can cause support piers to sink or shift over time, creating uneven pressure on the home's steel frame. We frequently find rusted-through metal piers and deteriorated wooden blocks that have lost their integrity due to prolonged ground moisture. These conditions can compromise the home's level, leading to significant and costly long-term damage if not addressed promptly.

Actionable Inspection Tips

To properly evaluate the foundation and support system, get underneath the home (if safe) and follow these steps:

• Check for Level: Place a long bubble level on the floor in multiple locations inside the home, especially near exterior walls and down the center marriage line. Any significant deviation indicates a potential support issue.
• Inspect Piers and Blocks: Look for cracked, crumbling, or leaning support piers. Ensure blocks are properly stacked and shimmed. Verify that piers are spaced correctly, typically no more than 8-10 feet apart.
• Examine the Steel Frame: Scan the I-beams for excessive rust, corrosion, or any signs of bending or twisting. Pay close attention to the outriggers extending from the main beams.
• Verify Tie-Downs: Check that the home is properly anchored with tie-downs. Look for loose, rusted, or broken straps and ensure they are securely fastened to both the frame and ground anchors.
• Assess the Underbelly: Inspect the vapor barrier (the plastic sheeting under the home) for rips, holes, or sagging areas, which could indicate moisture problems or pest intrusion.

The undercarriage is a complex and often hazardous environment. For a definitive assessment of the structural supports and foundation, a professional inspection is the safest and most reliable path. Understanding the condition of the foundation is key to protecting your investment.

6. Walls, Insulation, and Moisture Control

The walls of a mobile home are more than just partitions; they are a critical system for structural support, insulation, and moisture management. This part of a mobile home inspection checklist focuses on the integrity of the interior and exterior walls, the effectiveness of the insulation, and the presence of any moisture that could lead to mold or rot. Mobile homes often have thinner wall cavities than site-built homes, making them more susceptible to temperature fluctuations and moisture problems if not properly sealed and insulated.

In West Tennessee's humid climate, inadequate ventilation and poor vapor barriers can quickly lead to condensation inside wall cavities, causing unseen damage. We frequently discover soft spots around window and door frames where water has intruded, compromising the wall panels. Another common issue is hidden mold growth in closets or behind furniture, which poses a significant health risk and indicates a persistent moisture problem that must be addressed.

Actionable Inspection Tips

To thoroughly evaluate the walls, insulation, and moisture control, use these targeted steps:

• Feel for Temperature Differences: On a cool day, run your hand along interior walls. A wall that feels noticeably colder than others may have missing or settled insulation.
• Inspect for Water Stains and Damage: Look for discoloration, peeling paint, or bubbling wallpaper, especially under windows, near the floor, and in corners. These are classic signs of water intrusion.
• Check Inside Cabinets and Closets: These enclosed, dark spaces are prime areas for mold. Use a flashlight to inspect corners and back walls for any signs of fuzzy growth or musty odors.
• Press on the Walls: Gently press on the wall surfaces, particularly around windows and doors. Any sponginess or give can indicate that the underlying material has been damaged by moisture.

Given the hidden nature of many insulation and moisture issues, professional tools like a moisture meter or thermal imaging camera are invaluable for a conclusive assessment. A comprehensive inspection can reveal problems that are invisible to the naked eye, protecting your investment and your family's health.

7. Windows and Doors

Windows and doors are more than just entryways; they are crucial components of a mobile home's thermal envelope and defense against water intrusion. Unlike site-built homes, mobile homes can experience unique stress during transportation and setup, which often compromises the seals and frames of windows and doors. An inspection of these elements involves checking for proper operation, airtight seals, and signs of water damage, which are vital for energy efficiency and preventing moisture-related problems.

In West Tennessee's humid climate, failed window seals are a prevalent issue, leading to condensation between panes and reduced insulating properties. This trapped moisture not only obstructs the view but signals a breach that increases energy bills. We frequently find deteriorated weatherstripping around doors and cracked caulk around exterior window frames, creating easy pathways for drafts and rainwater. These seemingly minor issues can lead to significant interior wall damage and mold growth if left unaddressed.

Actionable Inspection Tips

To thoroughly evaluate all windows and doors, follow this systematic approach:

• Operate Everything: Open and close every single window and door. They should operate smoothly without sticking or requiring excessive force. Check all locking mechanisms to ensure they engage securely.
• Inspect Seals and Glazing: Look closely at the rubber or vinyl seals around the glass. Search for cracking, brittleness, or gaps. For double-pane windows, check for fogging or moisture between the panes, a clear sign of a failed seal.
• Search for Water Intrusion: Examine windowsills, the floor, and walls directly below and around each unit for water stains, peeling paint, or soft spots. These are definitive indicators of a leak.
• Check Weatherstripping and Caulk: Ensure weatherstripping on all exterior doors is intact and creates a firm seal when closed. Inspect the exterior caulk around window and door frames for any signs of cracking or separation from the siding.

Because these components are so integral to the home's performance, a professional eye can spot subtle signs of failure that might otherwise be missed. A complete mobile home inspection checklist will always prioritize these potential points of failure to protect your investment.

8. Kitchen Appliances and Cabinetry

The kitchen is often the heart of the home, and in a mobile home, its functionality is paramount. A thorough inspection of the kitchen appliances and cabinetry is a key part of any mobile home inspection checklist, as these components are subject to daily wear and can be costly to replace. Mobile homes frequently utilize compact or specialized appliances designed for smaller spaces, which can present unique challenges for repair or replacement. This assessment goes beyond a simple visual check, involving functional tests of each appliance and a detailed examination of cabinets and countertops.

In West Tennessee's humid climate, we often see moisture-related issues affecting kitchen cabinetry, such as warped particleboard under sinks from slow plumbing leaks or delamination of countertop surfaces. Furthermore, older mobile homes may have original appliances that are inefficient or nearing the end of their service life. Identifying these issues upfront allows a potential buyer to budget for necessary upgrades or repairs, preventing unexpected expenses after moving in.

Actionable Inspection Tips

To accurately evaluate the kitchen's condition, follow these steps:

• Test Every Appliance: Don't just look; operate everything. Turn on all stove burners, test the oven, run the dishwasher (if present), and check the microwave. Verify that the refrigerator and freezer are cooling to the proper temperatures (below 40°F for the fridge, around 0°F for the freezer).
• Inspect Cabinets and Countertops: Open and close all cabinet doors and drawers to check for proper alignment, smooth operation, and secure hardware. Look under the sink for any signs of water stains, mold, or active leaks. Carefully examine countertops for cracks, chips, burns, or water damage, especially around the sink and faucet.
• Check for Proper Ventilation: Ensure the range hood or ventilation fan above the stove is functioning correctly. Proper ventilation is crucial for removing smoke, grease, and moisture, which helps maintain indoor air quality and prevents damage to surrounding surfaces.
• Document Brands and Ages: Note the brand, model, and approximate age of each major appliance. This information is valuable for researching potential repair costs, finding replacement parts, or determining if they are nearing the end of their expected lifespan.

Given the potential for hidden plumbing leaks and electrical faults with aging appliances, a professional inspection is the best way to uncover underlying problems. An expert can identify issues that are not immediately obvious, providing a clear picture of the kitchen's true condition.

9. Bathroom Fixtures and Conditions

Bathrooms in any home are high-moisture zones, but in the compact design of a mobile home, they are particularly susceptible to issues that can escalate quickly. A thorough check of bathroom fixtures and conditions is a non-negotiable part of a mobile home inspection checklist. This step involves more than just flushing a toilet; it's about identifying hidden water damage, poor ventilation, and electrical hazards that can compromise the home's safety and structural soundness. From the subfloor beneath the tub to the exhaust fan in the ceiling, every component demands careful scrutiny.

In West Tennessee's humid climate, inadequate bathroom ventilation is a primary cause of persistent mold and mildew growth. We often find exhaust fans that are either non-functional or, worse, vent directly into the crawlspace or attic instead of the exterior. This traps moisture where it can rot structural components and degrade indoor air quality. Another common issue is soft spots in the subfloor around the base of the toilet or along the edge of the shower, a clear sign of a slow, long-term leak that has weakened the underlying materials.

Actionable Inspection Tips

To properly assess the bathroom's condition, follow these steps:

• Test All Fixtures: Run the shower, tub, and sink faucets to check for adequate water pressure and proper drainage. Listen for gurgling sounds that might indicate a venting problem.
• Inspect for Leaks and Damage: Check for proper caulking around the tub, shower, and sink. Feel the walls and floor, especially around the base of the toilet and tub, for any softness, sponginess, or discoloration that points to water damage.
• Verify Ventilation: Turn on the exhaust fan to ensure it operates correctly. If possible, confirm that it vents to the outside of the home, not into an enclosed space. Look for signs of mold or mildew on the ceiling and in corners.
• Check Electrical Safety: Ensure that electrical outlets located within six feet of a water source are GFCI-protected. Test these outlets to confirm they are functioning properly.

A musty odor in the bathroom is a significant red flag that should never be ignored. Given the potential for hidden moisture damage, having a professional evaluate the space is crucial for uncovering problems that may not be visible to the untrained eye.

10. Flooring and Subflooring Integrity

The flooring system in a mobile home is more than just a surface to walk on; it’s a crucial structural component. Unlike site-built homes with deep foundations, mobile home floors are built on a steel chassis with wood joists and particle board or plywood subflooring. This construction makes them particularly susceptible to moisture damage from plumbing leaks, high humidity, and poor underbelly ventilation, which can lead to soft spots, rot, and even catastrophic failure. A thorough inspection of the flooring and subflooring is essential for assessing the home's safety and long-term stability.

In West Tennessee’s humid climate, moisture is a constant threat. Inadequate vapor barriers in the crawlspace or slow plumbing leaks can saturate the subfloor, causing it to weaken and decay over time. We frequently encounter severe rot under bathrooms and kitchens, where a small leak from a toilet or sink has gone unnoticed. These issues not only create an unsafe walking surface but can also compromise the floor joists, requiring extensive and costly repairs that are a key part of any complete mobile home inspection checklist.

Actionable Inspection Tips

To properly evaluate the flooring and subflooring, follow these steps:

• Perform a "Gravity Test": Carefully walk across every square foot of the home, paying close attention to how the floor feels. Note any areas that feel soft, spongy, bouncy, or excessively sloped.
• Check High-Risk Areas: Focus on floors around toilets, bathtubs, sinks, dishwashers, and water heaters. Look for discoloration, peeling vinyl, or other signs of water damage on wood floors and other surfaces.
• Inspect from Below: If accessible, use a flashlight to examine the subfloor and floor joists from the crawlspace. Look for dark stains, fungal growth, or wood that appears damp or crumbly.
• Verify Levelness: While some minor settling is normal, significant slopes or unevenness can indicate foundation issues or severe structural decay in the floor system.
