A home inspection isn't just about identifying problems with the house. It is identifying the problems and finding a solution for it. Some common mistakes made by home buyers are not researching the inspector, not attending the inspection, not reading the inspection report and not getting a presale inspection.
1. Not researching the inspector
Too many buyers and sellers take whatever name is recommended without doing research. You want a certified professional who stays current. You're looking for an inspector who can analyze the home's strengths and weaknesses -- then explain them.
2. Not attending the inspection
Attendance may not be mandatory, but it's a good idea. Simply reading the inspection report isn't enough for most homeowners to get the full picture. A good inspector can give you an estimate of how much money you'll need to put into repairs and upgrades and talk about how well that fits your budget.
3. Not reading the inspection report
Too many buyers and sellers just glance at the inspection report. You need someone who uses "clear, concise" language in person and in written reports. A knowledgeable pro will state simply what's wrong with the house and what it will take to fix.
4. Not getting a presale inspection
Many sellers elect to leave the presale inspection to the buyers but that's a mistake. When the buyers get an inspection (and if they're smart, they will), the sellers will have little time to complete repairs and keep the sale on track. But if sellers have the home inspected before putting it on the market, they have more time to get repairs done, he says. With the extra time, they can shop around and control costs. You should find an inspector long before you have (or make) an offer.
