The General Inspection is the most important inspection, always get one of these. Your general inspector will recommend any specialty followup inspections (Foundation, Mold, Chimney, Drainage, Roof, Plumber,HVAC) if they feel that they are warranted. For Houses I recommend Sewerline Inspections and Permit Reports too, and if it has a chimney, and chimney inspection also. If you smell mold or there is evidence of water damage or you have bad allergies, a mold inspection might be a good idea. Surveys and Geological Inspections are for hillside properties. Tree inspections and Soil Tests are for builders.
Some buyers are overwhelmed when they first receive their inspection report, these inspection reports usually average 30-40 pages. Keep in mind, that if the inspector doesn’t find anything wrong with the property- it looks they are not doing their job! An inspector is going to point out every single thing they find wrong with the property. Don’t be discouraged by the report, chances are it is still a good property.
Remember when I said houses aren’t perfect? Minor things such as cracked sidewalks that might be a trip hazard.
