Preliminary House Inspection
The purpose of your personal inspection is only to eliminate those properties from consideration that have too many obvious deficiencies. It is not designed to take the place of a professional house inspection. If a house passes your initial "tests" (location, wants and needs, etc.) you will probably want to schedule a second showing where you can spend an hour or so doing an inspection of the house.

What to look for:

Foundation
Are there obvious cracks? Any apparent shifts in the foundation?
Roof
Does it appear new, old, or of an indeterminate age? What is the overall condition?
Evidence of leaks
Check inside as well as outside. Check all ceilings and areas around windows.
Basement or crawlspace
Is there dampness? Is there adequate insulation?
Attic
How does the interior of the roof structure look?
Quality and workmanship
In general and in any additions
Apparent energy efficiency
Does the house appear tightly sealed?
Electrical
Any obvious malfunctions?
Plumbing
Any unusual noises or malfunctions?
Appliance condition
What is the age and condition of the stove, dishwasher, refrigerator (if included), etc.?
Heating/cooling system
Does it seem to do the job heating or cooling?
Exterior
Is the house going to need repairs or paint soon?
Lot
Does the drainage appear good--and away from the house?
Lot
Are there any trees encroaching on the roof or foundation?
