“Ron Sierra was very professional and did a great job. When buying a home you want to make sure the home is safe and that you are aware of any issues with the house that need to be fixed. Ron went through the entire home inspection thoroughly. He explained what he would be looking for, what should be fixed and what was the most important things to take care of.
