When you put your offer in to the seller, one of the conditions should be that you have the right to a favorable home inspection report.
To ensure that you hire the right inspector, talk to your real estate agent, ask for recommendations, then make sure that the inspector is certified (at the moment, the home inspection industry is not regulated or licensed). Ask the inspectors how many inspections they have completed and what type of report you will receive. Also confirm how long it will take to receive the final report.
Buying a home is a significant investment and life event. The more you can learn about your potential purchase, the better. Don’t get caught blind-sided for the sake of $400 to $500!!
