In the last 10-15 years, buyers have hired home inspectors to look at the homes that they are thinking about purchasing. (Prior to that, some might have had one of their relatives look at the house and they would surely find all kinds of issues!)
The first thing a buyer needs to do is find a “qualified” inspector who can not only inpsect the home, but also teach the buyer about the systems in the home. This should include recommendations for maintaining the systems as well as possible upgrades.
The purpose of the inspection is to make sure that the house does not have any structural problems, health issues, mechanical conditions that compromise the working condition of items, or safety conditions.
If possible it is a good idea for buyers to attend the inspection so that they can converse with the inspector at the house about the systems and structure. The first hand information can be priceless especially for first time home owners.
Once the inspection is complete the buyers will have an opportunity to accept the property in its condition, or negotiate with the seller to repair/replace items that are of concern. Just a word of caution, though. It’s not a good idea to ask the seller for silly things, like replacing the batteries in garage door openers. The only thing that will accomplish is a rift between the buyer and seller. Sometimes the sellers aren’t even aware of some of the problems that may be found. Most buyers and sellers can come to an agreement on items that are discovered in the home inspection.
