Think a whole-house inspection is enough?

Due diligence: it’s a fancy way of saying that a homebuyer should not depend on the word of the seller (even though, legally, the seller must reveal all known defects in the home) but has an obligation to thoroughly investigate the property. The due diligence period typically runs from the time the purchase contract is signed until a date mutually agreed upon by the buyer and the seller.

Due diligence is something far too many homebuyers take lightly and it’s a pity. Not only will the process ensure that the home is in acceptable condition, but proof that you performed thorough due diligence will be required should you end up in court with the seller.

Any home may be hiding an expensive secret and it’s up to you to get it to spill the beans. Following you’ll find a few of the more common home inspections buyers perform during the due diligence period.

The whole-house inspection

Call this one the mack-daddy of inspections; it’s the one the real estate industry insists must be performed. Carried out by a professional, all of the home’s systems will be checked, from the HVAC to plumbing and electrical. Remember, however, that this is a visual inspection. The inspector cannot tell you what might be hiding behind the walls or in areas of the home’s system that aren’t visible to the naked eye.

The inspector will also make note of potential problems – those that may occur in the near future. Examples of this include faulty grading of the landscaping and possible moisture intrusion.

“Conditions at a home for sale can change radically in only a day or two, so a home inspection is not meant to guarantee what condition a home will be in when the transaction closes,” claims Nick Gromicko and Kenton Shepard of the International Association of Home Inspectors (InterNACHI) “It’s not uncommon for conditions to change between the time of the inspection and the closing date,” they conclude.

The organization offers an excellent resource about what to expect from a home inspection on its website.

Pest inspection

Some creepy crawlies are benign – staying put in their hiding places, causing no problems. Others, however, can wreak enough havoc to bring a home crumbling down around its occupants. These are wood-boring insects, such as powder post beetles, carpenter ants and termites. Then there are the fungal organisms that cause rot in the home’s timbers, which may eventually turn brittle and decay into powder.

Unless you know what to look for, evidence of a pest infestation and even the damage caused by these pests can be difficult to find. The fix, when caught early, is far less expensive than if the problem is left to fester. Most homeowners in the U.S. spend between $237 to $847 for termite control service. An extensive infestation, however, can be substantially more expensive to cure.

Well and septic tests

Purchasing rural property comes with a whole different set of considerations. Typically located far from city services, the drinking water is supplied via a well and sanitation from a cistern or septic system.

Since problems with both are almost impossible to ascertain to the non-professional, an inspection is always a good idea. The typical septic system inspection includes pumping out the system so that a visual inspection of the tank and distribution box can be performed. The inspector will look for signs of decay, including missing or broken parts. Americans typically pay between $280 and $523 to have a septic tank pumped. The price can be as low as $200 or as high as $900, according to

Often, a percolation test (also known as a “perc test”) will be performed. The results will determine if the soil is adequately absorbing water which, in turn, tells the inspector if the lines are functioning properly.

Since the national average cost of well pump repairs is nearly $770, but may run as high as $2,000, if the home of your dreams’ primary water source is well water, it makes sense to have the system thoroughly checked before agreeing to go through with the purchase. Faulty pumps can cause the motor to stall or run continuously and low water pressure.

You’ll also want to have the water quality tested. Contaminants obviously pose a risk and you won’t necessarily see, taste or smell their presence. Your lender may require the tests but if it doesn’t, hire a professional. The U.S. Environmental Protection agency suggests that you have the water tested for nitrates/nitrites, coliform and pH. You may also want to look for copper, arsenic, radon and lead. Get more information from the EPA online, here.

Indoor air testing

Many homeowners routinely check the air in their homes in the winter for radon, an odorless, colorless radioactive gas. It enters the home through cracks and, as mentioned above, well water. Concentrations of the gas are naturally higher in the winter, when homes are buckled up tight against the elements.

Radon is a carcinogen and, in fact, is the second leading cause of lung cancer in the country, according to the National Cancer Institute.

Furthermore, the U.S. Surgeon General urges that all homes be tested. Testing can be performed with DIY test kits or by professionals. Mitigation, on the other hand, requires the help of a professional.

Lead-based paint

Homes built before 1978 were typically painted with products that contained lead. If you have small children, it is imperative that you determine if the home you hope to purchase has lead-based paint.

This is because, according to the United States Department of Housing and Urban Development, the absorption of lead into the body, either by breathing the dust or ingesting paint chips (which small children often do), may lead to damage to the liver, brain and other vital organs.

The EPA requires that homeowners disclose potential lead problems to buyers but not all homeowners are aware of what’s in the paint on their walls. So, if the home was built prior to 1978, be safe and have it tested for lead-based paint. You can learn more about this toxic paint on the EPA’s website.

Of course, these are not the only optional tests you may wish to have performed on the new home. If you suspect structural problems, consult with an engineer. Roof not up to snuff? Call a roofing professional. Due diligence is not only your legal obligation and helps protect your pocketbook, but it is important to your family’s health and safety as well.
