The Operating Systems, Lower Level, Interior and Exterior Inspection sections are EXTREMELY condensed versions of those found in our home inspection book: Home Inspection Business From A to Z
Real Estate Appraisers are not required to be home inspectors. However, I will include these sections anyway to give you some basic details about home inspections.
Check the bathroom walls and floors for any structural problems or settlement cracks. Check the condition of the bathroom wall and floor coverings. Most houses have ceramic tile floor coverings and part of the walls may have tile coverings. In some houses you'll find carpeting on the bathroom floors. Carpeting isn't used very often because of the possibility of it getting wet. Lift up a corner of the carpet to see what's underneath. Sometimes there are cracked and damaged tiles or water stains.
Press on some tiles, especially in the bathtub and shower area to see if any are loose. Check to see if the tiles need to be caulked between the joints to help prevent water leaks behind the walls. Some shower and tub areas are made of a premolded plastic and fiberglass material. Check these for any cracks and proper caulking around the edges.
Check the condition of the bathroom sink area for any cracks or loose sections. Make sure the drain stop mechanism in the sink is working. Often they won't be. Test any bathroom ventilation fans for proper operation. See if there's at least one electrical outlet and that it has Ground Fault Circuit Interrupter protection. Sometimes in older houses there won't be any grounded outlets in the bathroom which is an inconvenience and safety hazard.
Check the water pressure and drainage. There are usually local guidelines about what the minimum allowable water pressure should be, but generally, most houses will always meet the minimum criteria. After running the water for a few minutes check to see if the sink and tub drain properly. Sometimes they'll drain very slowly and need to be unclogged.
