Worth the investment?
According to Investopedia, Remember that an inspection is:
Not the sole determinant for buying a house. Maybe you’re willing to make some renovations to the house with these problems. The inspection will help you determine exactly how many you’ll need to do.
Never free and clear of problems. An inspection will always find a problem with a home. Even new home constructions will have minor issues that need to be addressed.
Not about getting all the fixes done. No seller is going to fix everything for you. They may negotiate on some of them, but expecting a resolution of all issues is unreasonable.
