This is just a short message to inform you of the typical issues found in most home inspections. You may want to take a look around your home now to prevent these items from becoming an issue in your home inspection.
Faucets and Pipes
That leaky pipe may not really bother you, but the home inspector will find it!
Cracked glass or leaking window seals are not acceptable to most buyers.
Ground Fault Circuit Interrupters (GFCI’s)
These should ALL be in working order. To test them, just push the ‘test’ button. This will turn off power to the outlet. Plug in an appliance to make sure it worked (no power to the outlet). Press the reset button and the appliance should now work. Older houses may not have GFCI’s, but if yours does, they should work.
Check for leaks and crack in the toilet bowls. Make sure nothing is loose.
Creative Wiring 
If you’ve been inventing your own wiring system out on the patio or in the garage, this can be a negative issue. Most buyers are fearful of exposed wiring. Wiring should be in a conduit, and/or junction box. Remove any exposed, exterior, extension cords, or “do-it-yourself” wiring.
Air Filters
Change them!  Dirty air filters affect the performance of the heating/cooling system. Consider having the unit serviced and cleaned so that it will operate at its highest efficiency.
Any missing shingles or cracked tiles should be replaced. Any flashing that needs resealing should be resealed. 
All doors should latch properly, and lock if a lock is installed. You will need to provide a key for each lock at closing.
Pool Equipment
Pool equipment should operate properly. No leaking pipes or valves please.
Sprinkler Systems
If the valves are leaking or heads are broken, the inspector will find it.
If you use the services of a professional pest control company, you may want them to take a look.
