Before you buy a home, one of the things you should do is to have the home checked out by a professional property inspector. Buying a home is expensive enough as it is - why would you choose to fork over another $300 or more if you're not required to?

The Pre Purchase Inspection Contingency
A pre purchase inspection is important in that it can be used as a contingency in your purchase offer. This contingency provides that if significant defects are revealed by a pre purchase inspection, you can back out of your offer, free of penalty, within a certain timeframe. The potential problems a home can have must be pretty serious if they could allow you to walk away from such a significant contract.

The inspector should note:

• whether each problem is a safety issue, major defect, or minor defect
• which items need replacement and which should be repaired or serviced
• items that are suitable for now but that should be monitored closely

A really great inspector will even tell you about routine maintenance that should be performed, which can be a great help if you are a first-time homebuyer.

The following list will give you a general idea of what to expect.

Exterior
• Exterior walls - The inspector will check for damaged or missing siding, cracks and whether the soil is in excessively close contact with the bottom of the house, which can invite wood-destroying insects. The inspector will let you know which problems are cosmetic and which could be more serious.
• Foundation - If the foundation is not visible, and it usually is not, the inspector will not be able to examine it directly, but they can check for secondary evidence of foundation issues, like cracks or settling.
• Grading - The inspector will let you know whether the grading slopes away from the house as it should. If it doesn't, water could get into the house and cause damage, and you will need to either change the slope of the yard or install a drainage system.
• Garage or carport - The inspector will test the garage door for proper opening and closing, check the garage framing if it is visible and determine if the garage is properly ventilated (to prevent accidental carbon monoxide poisoning). If the water heater is in the garage, the inspector will make sure it is installed high enough off the ground to minimise the risk of explosion from petrol fumes mingling with the heater's flame.
• Roof - The inspector will check for areas where roof damage or poor installation could allow water to enter the home, such as loose, missing or improperly secured shingles and cracked or damaged mastic around vents. He will also check the condition of the gutters.

Interior
• Plumbing - The home inspector will check all faucets and showers, look for visible leaks, such as under sinks and test the water pressure. He or she will also identify the kind of pipes the house has, if any pipes are visible. The inspector may recommend a secondary inspection if the pipes are old to determine if or when they might need to be replaced and how much the work would cost.
• Electrical - The inspector will identify the kind of wiring the home has, test all the outlets and make sure there are functional ground fault circuit interrupters (which can protect you from electrocution, electric shock and electrical burns) installed in areas like the bathrooms, kitchen, garage and outdoors. They will also check your electrical panel for any safety issues and check your electrical outlets to make sure they do not present a fire hazard.
• Heating, ventilation and air conditioning (HVAC) - The inspector will look at your HVAC system to estimate the age of the furnace and air conditioner, determine if they function properly and recommend repairs or maintenance. An inspector can also give you an idea of the age of the home's ducting, whether it might have leaks, if your home has sufficient insulation to minimise your energy bills and whether there is any asbestos insulation.
• Water heater - The home inspector will identify the age of the heater and determine if it is properly installed and secured. The inspector will also let you know what kind of condition it is in and give you a general idea of how many years it has left.
• Kitchen appliances – The inspector will sometimes check kitchen appliances that come with the home to make sure they work, but these are not always part of the inspection. Be sure to ask the inspector which appliances are not included so that you can check them yourself.
• Laundry room - The inspector will make sure the laundry room is properly vented. A poorly maintained dryer-exhaust system can be a serious fire hazard.
• Bathrooms - The inspector will check for visible leaks, properly secured toilets, adequate ventilation and other issues. If the bathroom does not have a window and/or a ventilation fan, mold and mildew can become problems and moisture can warp wood cabinets over time.

After the Inspection
Once you have the results of your pre purchase inspection, you have several options.
• If the problems are too significant or too expensive to fix, you can choose to walk away from the purchase, as long as the purchase contract has an inspection contingency.
• For problems large or small, you can ask the seller to fix them, reduce the purchase price, or to give you a cash credit at closing to fix the problems yourself - this is where a home inspection can pay for itself several times over.
• If these options aren't viable in your situation (for example, if the property is bank-owned and being sold as-is), you can get estimates to fix the problems yourself and come up with a plan for repairs in order of their importance and affordability once you own the property.
